Every year, scammers cook up new ways to trick people, and 2025 was no exception. Over the past year, our anti-phishing system thwarted more than 554 million attempts to follow phishing links, while our Mail Anti-Virus blocked nearly 145 million malicious attachments. To top it off, almost 45% of all emails worldwide turned out to be spam. Below, we break down the most impressive phishing and spam schemes from last year. For the deep dive, you can read the full Spam and Phishing in 2025 report on Securelist.

Phishing for fun

Music lovers and cinephiles were prime targets for scammers in 2025. Bad actors went all out creating fake ticketing aggregators and spoofed versions of popular streaming services.

On these fake aggregator sites, users were offered “free” tickets to major concerts. The catch? You just had to pay a small “processing fee” or “shipping cost”. Naturally, the only thing being delivered was your hard-earned cash straight into a scammer’s pocket.

With streaming services, the hustle went like this: users received a tempting offer to, say, migrate their Spotify playlists to YouTube by entering their Spotify credentials. Alternatively, they were invited to vote for their favorite artist in a chart — an opportunity most fans find hard to pass up. To add a coat of legitimacy, scammers name-dropped heavy hitters like Google and Spotify. The phishing form targeted multiple platforms at once — Facebook, Instagram, or email — requiring users to enter their credentials to vote hand over their accounts.

In Brazil, scammers took it a step further: they offered users the chance to earn money just by listening to and rating songs on a supposed Spotify partner service. During registration, users had to provide their ID for Pix (the Brazilian instant payment system), and then make a one-time “verification payment” of 19.9 Brazilian reals (about $4) to “confirm their identity”. This fee was, of course, a fraction of the promised “potential earnings”. The payment form looked incredibly authentic and requested additional personal data — likely to be harvested for future attacks.

The “cultural date” scheme turned out to be particularly inventive. After matching and some brief chatting on dating apps, a new “love interest” would invite the victim to a play or a movie and send a link to buy tickets. Once the “payment” went through, both the date and the ticketing site would vanish into thin air. A similar tactic was used to sell tickets for immersive escape rooms, which have surged in popularity lately; the page designs mirrored real sites to lower the user’s guard.

Phishing via messaging apps

The theft of Telegram and WhatsApp accounts became one of the year’s most widespread threats. Scammers have mastered the art of masking phishing as standard chat app activities, and have significantly expanded their geographical reach.

On Telegram, free Premium subscriptions remained the ultimate bait. While these phishing pages were previously only seen in Russian and English, 2025 saw a massive expansion into other languages. Victims would receive a message — often from a friend’s hijacked account — offering a “gift”. To activate it, the user had to log in to their Telegram account on the attacker’s site, which immediately led to another hijacked account.

Another common scheme involved celebrity giveaways. One specific attack, disguised as an NFT giveaway, stood out because it operated through a Telegram Mini App. For the average user, spotting a malicious Mini App is much harder than identifying a sketchy external URL.

Finally, the classic vote for my friend messenger scam evolved in 2025 to include prompts to vote for the “city’s best dentist” or “top operational leader” — unfortunately, just bait for account takeovers.

Another clever method for hijacking WhatsApp accounts was spotted in China, where phishing pages perfectly mimicked the actual WhatsApp interface. Victims were told that due to some alleged “illegal activity”, they needed to undergo “additional verification”, which — you guessed it — ended up with a stolen account.

Impersonating Government Services

Phishing that mimics government messages and portals is a “classic of the genre”, but in 2025, scammers added some new scripts to the playbook.

In Russia, vishing attacks targeting government service users picked up steam. Victims received emails claiming an unauthorized login to their account, and were urged to call a specific number to undergo a “security check”. To make it look legit, the emails were packed with fake technical details: IP addresses, device models, and timestamps of the alleged login. Scammers also sent out phony loan approval notifications: if the recipient hadn’t applied for a loan (which they hadn’t), they were prompted to call a fake support team. Once the panicked victim reached an “operator”, social engineering took center stage.

In Brazil, attackers hunted for taxpayer numbers (CPF numbers) by creating counterfeit government portals. Since this ID is the master key for accessing state services, national databases, and personal documents, a hijacked CPF is essentially a fast track to identity theft.

In Norway, scammers targeted people looking to renew their driver’s licenses. A site mimicking the Norwegian Public Roads Administration collected a mountain of personal data: everything from license plate numbers, full names, addresses, and phone numbers to the unique personal identification numbers assigned to every resident. For the cherry on top, drivers were asked to pay a “license replacement fee” of 1200 NOK (over US$125). The scammers walked away with personal data, credit card details, and cash. A literal triple-combo move!

Generally speaking, motorists are an attractive target: they clearly have money and a car and a fear of losing it. UK-based scammers played on this by sending out demands to urgently pay some overdue vehicle tax to avoid some unspecified “enforcement action”. This “act now!” urgency is a classic phishing trope designed to distract the victim from a sketchy URL or janky formatting.

Let us borrow your identity, please

In 2025, we saw a spike in phishing attacks revolving around Know Your Customer (KYC) checks. To boost security, many services now verify users via biometrics and government IDs. Scammers have learned to harvest this data by spoofing the pages of popular services that implement these checks.

What sets these attacks apart is that, in addition to standard personal info, phishers demand photos of IDs or the victim’s face — sometimes from multiple angles. This kind of full profile can later be sold on dark web marketplaces or used for identity theft. We took a deep dive into this process in our post, What happens to data stolen using phishing?

AI scammers

Naturally, scammers weren’t about to sit out the artificial intelligence boom. ChatGPT became a major lure: fraudsters built fake ChatGPT Plus subscription checkout pages, and offered “unique prompts” guaranteed to make you go viral on social media.

The “earn money with AI” scheme was particularly cynical. Scammers offered passive income from bets allegedly placed by ChatGPT: the bot does all the heavy lifting while the user just watches the cash roll in. Sounds like a dream, right? But to “catch” this opportunity, you had to act fast. A special price on this easy way to lose your money was valid for only 15 minutes from the moment you hit the page, leaving victims with no time to think twice.

Across the board, scammers are aggressively adopting AI. They’re leveraging deepfakes, automating high-quality website design, and generating polished copy for their email blasts. Even live calls with victims are becoming components of more complex schemes, which we detailed in our post, How phishers and scammers use AI.

Booby-trapped job openings

Someone looking for work is a prime target for bad actors. By dangling high-paying remote roles at major brands, phishers harvested applicants’ personal data — and sometimes even squeezed them for small “document processing fees” or “commissions”.

In more sophisticated setups, “employment agency” phishing sites would ask for the phone number linked to the user’s Telegram account during registration. To finish “signing up”, the victim had to enter a “confirmation code”, which was actually a Telegram authorization code. After entering it, the site kept pestering the applicant for more profile details — clearly a distraction to keep them from noticing the new login notification on their phone. To “verify the user”, the victim was told to wait 24 hours, giving the scammers, who already had a foot in the door, enough time to hijack the Telegram account permanently.

Hype is a lie (but a very convincing one)

As usual, scammers in 2025 were quick to jump on every trending headline, launching email campaigns at breakneck speed.

For instance, following the launch of $TRUMP meme coins by the U.S. President, scam blasts appeared promising free NFTs from “Trump Meme Coin” and “Trump Digital Trading Cards”. We’ve previously broken down exactly how meme coins work, and how to (not) lose your shirt on them.

The second the iPhone 17 Pro hit the market, it became the prize in countless fake surveys. After “winning”, users just had to provide their contact info and pay for shipping. Once those bank details were entered, the “winner” risked losing not just the shipping fee, but every cent in their account.

Riding the Ozempic wave, scammers flooded inboxes with offers for counterfeit versions of the drug, or sketchy “alternatives” that real pharmacists have never even heard of.

And during the BLACKPINK world tour, spammers pivoted to advertising “scooter suitcases just like the band uses”.

Even Jeff Bezos’s wedding in the summer of 2025 became fodder for “Nigerian” email scams. Users received messages purportedly from Bezos himself or his ex-wife, MacKenzie Scott. The emails promised massive sums in the name of charity or as “compensation” from Amazon.

How to stay safe

As you can see, scammers know no bounds when it comes to inventing new ways to separate you from your money and personal data — or even stealing your entire identity. These are just a few of the wildest examples from 2025; you can dive into the full analysis of the phishing and spam threat landscape over at Securelist. In the meantime, here are a few tips to keep you from becoming a victim. Be sure to share these with your friends and family — especially kids, teens, and older relatives. These groups are often the main targets in the scammers’ crosshairs.

1. Check the URL before entering any data. Even if the page looks pixel-perfect, the address bar can give the game away.
2. Don’t follow links in suspicious messages, even if they come from someone you know. Their account could easily have been hijacked.
3. Never share verification codes with anyone. These codes are the master keys to your digital life.
4. Enable two-factor authentication everywhere you can. It adds a crucial extra hurdle for hackers.
5. Be skeptical of “too good to be true” offers. Free iPhones, easy money, and gifts from strangers are almost always a trap. For a refresher, check out our post, Phishing 101: what to do if you get a phishing email.
6. Install robust protection on all your devices. Kaspersky Premium automatically blocks phishing sites, malicious attachments, and spam blasts before you even have a chance to click. Plus, our Kaspersky for Android app features a three-tier anti-phishing system that can sniff out and neutralize malicious links in any message from any app. Read more about it in our post, A new layer of anti-phishing security in Kaspersky for Android.

With both spring and St. Valentine’s Day just around the corner, love is in the air — but we’re going to look at it through the lens of ultra-modern high-technology. Today, we’re diving into how technology is reshaping our romantic ideals and even the language we use to flirt. And, of course, we’ll throw in some non-obvious tips to make sure you don’t end up as a casualty of the modern-day love game.

New languages of love

Ever received your fifth video e-card of the day from an older relative and thought, “Make it stop”? Or do you feel like a period at the end of a sentence is a sign of passive aggression? In the world of messaging, different social and age groups speak their own digital dialects, and things often get lost in translation.

This is especially obvious in how Gen Z and Gen Alpha use emojis. For them, the Loudly Crying Face 😭 often doesn’t mean sadness — it means laughter, shock, or obsession. Meanwhile, the Heart Eyes emoji might be used for irony rather than romance: “Lost my wallet on the way home 😍😍😍”. Some double meanings have already become universal, like 🔥 for approval/praise, or 🍆 for… well, surely you know that by now… right?! 😭

Still, the ambiguity of these symbols doesn’t stop folks from crafting entire sentences out of nothing but emoji. For instance, a declaration of love might look something like this:

🤫❤️🫵

Or here’s an invitation to go on a date:

🫵🚶➡️💋🌹🍝🍷❓

By the way, there are entire books written in emojis. Back in 2009, enthusiasts actually translated the entirety of Moby Dick into emojis. The translators had to get creative — even paying volunteers to vote on the most accurate combinations for every single sentence. Granted it’s not exactly a literary masterpiece — the emoji language has its limits, after all — but the experiment was pretty fascinating: they actually managed to convey the general plot.

Unfortunately, putting together a definitive emoji dictionary or a formal style guide for texting is nearly impossible. There are just too many variables: age, context, personal interests, and social circles. Still, it never hurts to ask your friends and loved ones how they express tone and emotion in their messages. Fun fact: couples who use emojis regularly generally report feeling closer to one another.

However, if you are big into emojis, keep in mind that your writing style is surprisingly easy to spoof. It’s easy for an attacker to run your messages or public posts through AI to clone your tone for social engineering attacks on your friends and family. So, if you get a frantic DM or a request for an urgent wire transfer that sounds exactly like your best friend, double-check it. Even if the vibe is spot on, stay skeptical. We took a deeper dive into spotting these deepfake scams in our post about the attack of the clones.

Dating an AI

Of course, in 2026, it’s impossible to ignore the topic of relationships with artificial intelligence; it feels like we’re closer than ever to the plot of the movie Her. Just 10 years ago, news about people dating robots sounded like sci-fi tropes or urban legends. Today, stories about teens caught up in romances with their favorite characters on Character AI, or full-blown wedding ceremonies with ChatGPT, barely elicit more than a nervous chuckle.

In 2017, the service Replika launched, allowing users to create a virtual friend or life partner powered by AI. Its founder, Eugenia Kuyda — a Russian native living in San Francisco since 2010 — built the chatbot after her friend was tragically killed by a car in 2015, leaving her with nothing but their chat logs. What started as a bot created to help her process her grief was eventually released to her friends and then the general public. It turned out that a lot of people were craving that kind of connection.

Replika lets users customize a character’s personality, interests, and appearance, after which they can text or even call them. A paid subscription unlocks the romantic relationship option, along with AI-generated photos and selfies, voice calls with roleplay, and the ability to hand-pick exactly what the character remembers from your conversations.

However, these interactions aren’t always harmless. In 2021, a Replika chatbot actually encouraged a user in his plot to assassinate Queen Elizabeth II. The man eventually attempted to break into Windsor Castle — an “adventure” that ended in 2023 with a nine-year prison sentence. Following the scandal, the company had to overhaul its algorithms to stop the AI from egging on illegal behavior. The downside? According to many Replika devotees, the AI model lost its spark and became indifferent to users. After thousands of users revolted against the updated version, Replika was forced to cave and give longtime customers the option to roll back to the legacy chatbot version.

But sometimes, just chatting with a bot isn’t enough. There are entire online communities of people who actually marry their AI. Even professional wedding planners are getting in on the action. Last year, Yurina Noguchi, 32, “married” Klaus, an AI persona she’d been chatting with on ChatGPT. The wedding featured a full ceremony with guests, the reading of vows, and even a photoshoot of the “happy newlyweds”.

No matter how your relationship with a chatbot evolves, it’s vital to remember that generative neural networks don’t have feelings — even if they try their hardest to fulfill every request, agree with you, and do everything it can to “please” you. What’s more, AI isn’t capable of independent thought (at least not yet). It’s simply calculating the most statistically probable and acceptable sequence of words to serve up in response to your prompt.

Love by design: dating algorithms

Those who aren’t ready to tie the knot with a bot aren’t exactly having an easy time either: in today’s world, face-to-face interactions are dwindling every year. Modern love requires modern tech! And while you’ve definitely heard the usual grumbling, “Back in the day, people fell in love for real. These days it’s all about swiping left or right!” Statistics tell a different story. Roughly 16% of couples worldwide say they met online, and in some countries that number climbs to as high as 51%.

That said, dating apps like Tinder spark some seriously mixed emotions. The internet is practically overflowing with articles and videos claiming these apps are killing romance and making everyone lonely. But what does the research say?

In 2025, scientists conducted a meta-analysis of studies investigating how dating apps impact users’ wellbeing, body image, and mental health. Half of the studies focused exclusively on men, while the other half included both men and women. Here are the results: 86% of respondents linked negative body image to their use of dating apps! The analysis also showed that in nearly one out of every two cases, dating app usage correlated with a decline in mental health and overall wellbeing.

Other researchers noted that depression levels are lower among those who steer clear of dating apps. Meanwhile, users who already struggled with loneliness or anxiety often develop a dependency on online dating; they don’t just log on for potential relationships, but for the hits of dopamine from likes, matches, and the endless scroll of profiles.

However, the issue might not just be the algorithms — it could be our expectations. Many are convinced that “sparks” must fly on the very first date, and that everyone has a “soulmate” waiting for them somewhere out there. In reality, these romanticized ideals only surfaced during the Romantic era as a rebuttal to Enlightenment rationalism, where marriages of convenience were the norm.

It’s also worth noting that the romantic view of love didn’t just appear out of thin air: the Romantics, much like many of our contemporaries, were skeptical of rapid technological progress, industrialization, and urbanization. To them, “true love” seemed fundamentally incompatible with cold machinery and smog-choked cities. It’s no coincidence, after all, that Anna Karenina meets her end under the wheels of a train.

Fast forward to today, and many feel like algorithms are increasingly pulling the strings of our decision-making. However, that doesn’t mean online dating is a lost cause; researchers have yet to reach a consensus on exactly how long-lasting or successful internet-born relationships really are. The bottom line: don’t panic, just make sure your digital networking stays safe!

How to stay safe while dating online

So, you’ve decided to hack Cupid and signed up for a dating app. What could possibly go wrong?

Deepfakes and catfishing

Catfishing is a classic online scam where a fraudster pretends to be someone else. It used to be that catfishers just stole photos and life stories from real people, but nowadays they’re increasingly pivoting to generative models. Some AIs can churn out incredibly realistic photos of people who don’t even exist, and whipping up a backstory is a piece of cake — or should we say, a piece of prompt. By the way, that “verified account” checkmark isn’t a silver bullet; sometimes AI manages to trick identity verification systems too.

To verify that you’re talking to a real human, try asking for a video call or doing a reverse image search on their photos. If you want to level up your detection skills, check out our three posts on how to spot fakes: from photos and audio recordings to real-time deepfake video — like the kind used in live video chats.

Phishing and scams

Picture this: you’ve been hitting it off with a new connection for a while, and then, totally out of the blue, they drop a suspicious link and ask you to follow it. Maybe they want you to “help pick out seats” or “buy movie tickets”. Even if you feel like you’ve built up a real bond, there’s a chance your match is a scammer (or just a bot), and the link is malicious.

Telling you to “never click a malicious link” is pretty useless advice — it’s not like they come with a warning label. Instead, try this: to make sure your browsing stays safe, use a Kaspersky Premium that automatically blocks phishing attempts and keeps you off sketchy sites.

Keep in mind that there’s an even more sophisticated scheme out there known as “Pig Butchering”. In these cases, the scammer might chat with the victim for weeks or even months. Sadly, it ends badly: after lulling the victim into a false sense of security through friendly or romantic banter, the scammer casually nudges them toward a “can’t-miss crypto investment” — and then vanishes along with the “invested” funds.

Stalking and doxing

The internet is full of horror stories about obsessed creepers, harassment, and stalking. That’s exactly why posting photos that reveal where you live or work — or telling strangers about your favorite local hangouts — is a bad move. We’ve previously covered how to avoid becoming a victim of doxing (the gathering and public release of your personal info without your consent). Your first step is to lock down the privacy settings on all your social media and apps using our free Privacy Checker tool.

We also recommend stripping metadata from your photos and videos before you post or send them; many sites and apps don’t do this for you. Metadata can allow anyone who downloads your photo to pinpoint the exact coordinates of where it was taken.

Finally, don’t forget about your physical safety. Before heading out on a date, it’s a smart move to share your live geolocation, and set up a safe word or a code phrase with a trusted friend to signal if things start feeling off.

Sextortion and nudes

We don’t recommend ever sending intimate photos to strangers. Honestly, we don’t even recommend sending them to people you do know — you never know how things might go sideways down the road. But if a conversation has already headed in that direction, suggest moving it to an app with end-to-end encryption that supports self-destructing messages (like “delete after viewing”). Telegram’s Secret Chats are great for this (plus — they block screenshots!), as are other secure messengers. If you do find yourself in a bad spot, check out our posts on what to do if you’re a victim of sextortion and how to get leaked nudes removed from the internet.

The Olympic Games are more than just a massive celebration of sports; they’re a high-stakes business. Officially, the projected economic impact of the Winter Games — which kicked off on February 6 in Italy — is estimated at 5.3 billion euros. A lion’s share of that revenue is expected to come from fans flocking in from around the globe — with over 2.5 million tourists predicted to visit Italy. Meanwhile, those staying home are tuning in via TV and streaming. According to the platforms, viewership ratings are already hitting their highest peaks since 2014.

But while athletes are grinding for medals and the world is glued to every triumph and heartbreak, a different set of “competitors” has entered the arena to capitalize on the hype and the trust of eager fans. Cyberscammers of all stripes have joined an illegal race for the gold, knowing full well that a frenzy is a fraudster’s best friend.

Kaspersky experts have tracked numerous fraudulent schemes targeting fans during these Winter Games. Here’s how to avoid frustration in the form of fake tickets, non-existent merch, and shady streams, so you can keep your money and personal data safe.

Tickets to nowhere

The most popular scam on this year’s circuit is the sale of non-existent tickets. Usually, there are far fewer seats at the rinks and slopes than there are fans dying to see the main events. In a supply-and-demand crunch, folks scramble for any chance to snag those coveted passes, and that’s when phishing sites — clones of official vendors — come to the “rescue”. Using these, bad actors fish for fans’ payment details to either resell them on the dark web or drain their accounts immediately.

Remember: tickets for any Olympic event are sold only through the authorized Olympic platform or its listed partners. Any third-party site or seller outside the official channel is a scammer. We’re putting that play in the penalty box!

A fake goalie mitt, a counterfeit stick…

Dreaming of a Sydney Sweeney — sorry, Sidney Crosby — jersey? Or maybe you want a tracksuit with the official Games logo? Scammers have already set up dozens of fake online stores just for you! To pull off the heist, they use official logos, convincing photos, and padded rave reviews. You pay, and in return, you get… well, nothing but a transaction alert and your card info stolen.

I want my Olympic TV!

What if you prefer watching the action from the comfort of your couch rather than trekking from stadium to stadium, but you’re not exactly thrilled about paying for a pricey streaming subscription? Maybe there’s a free stream out there?

Sure thing! Five seconds of searching and your screen is flooded with dozens of “cheap”, “exclusive”, or even “free” live streams. They’ve got everything from figure skating to curling. But there’s a catch: for some reason — even though it’s supposedly free — a pop-up appears asking for your credit card details.

You type them in and hit “Play”, but instead of the long-awaited free skate program, you end up on a webcam ad site or somewhere even sketchier. The result: no show for you. At best, you were just used for traffic arbitrage; at worst, they now have access to your bank account. Either way, it’s a major bummer.

Defensive tactics

Scammers have been ripping off sports fans for years, and their payday depends entirely on how well they can mimic official portals. To stay safe, fans should mount a tiered defense: install reliable security software to block phishing, and keep a sharp eye on every URL you visit. If something feels even slightly off, never, ever enter your personal or payment info.

• Stick to authorized channels for tickets. Steer clear of third-party resellers and always double-check info on the official Olympic website.
• Use legitimate streaming services. Read the reviews and don’t hand over your credit card details to unverified sites.
• Be wary of Olympic merch and gift vendors. Don’t get baited by “exclusive” offers or massive discounts from unknown stores. Only buy from official retail partners.
• Avoid links in emails, direct messages, texts, or ads offering free tickets, streams, promo codes, or prize giveaways.
• Deploy a robust security solution. For instance, Kaspersky Premium automatically shuts down phishing attempts and blocks dangerous websites, malicious ads, and credit card skimmers in real time.

AI tool Vercel was abused by cybercriminals to create a Malwarebytes lookalike website.

Cybercriminals no longer need design or coding skills to create a convincing fake brand site. All they need is a domain name and an AI website builder. In minutes, they can clone a site’s look and feel, plug in payment or credential-stealing flows, and start luring victims through search, social media, and spam.

One side effect of being an established and trusted brand is that you attract copycats who want a slice of that trust without doing any of the work. Cybercriminals have always known it is much easier to trick users by impersonating something they already recognize than by inventing something new—and developments in AI have made it trivial for scammers to create convincing fake sites.​​

Registering a plausible-looking domain is cheap and fast, especially through registrars and resellers that do little or no upfront vetting. Once attackers have a name that looks close enough to the real thing, they can use AI-powered tools to copy layouts, colors, and branding elements, and generate product pages, sign-up flows, and FAQs that look “on brand.”

A flood of fake “official” sites

Data from recent holiday seasons shows just how routine large-scale domain abuse has become.

Over a three‑month period leading into the 2025 shopping season, researchers observed more than 18,000 holiday‑themed domains with lures like “Christmas,” “Black Friday,” and “Flash Sale,” with at least 750 confirmed as malicious and many more still under investigation. In the same window, about 19,000 additional domains were registered explicitly to impersonate major retail brands, nearly 3,000 of which were already hosting phishing pages or fraudulent storefronts.

These sites are used for everything from credential harvesting and payment fraud to malware delivery disguised as “order trackers” or “security updates.”

Attackers then boost visibility using SEO poisoning, ad abuse, and comment spam, nudging their lookalike sites into search results and promoting them in social feeds right next to the legitimate ones. From a user’s perspective, especially on mobile without the hover function, that fake site can be only a typo or a tap away.​

When the impersonation hits home

A recent example shows how low the barrier to entry has become.

We were alerted to a site at installmalwarebytes[.]org that masqueraded from logo to layout as a genuine Malwarebytes site.

Close inspection revealed that the HTML carried a meta tag value pointing to v0 by Vercel, an AI-assisted app and website builder.

The tool lets users paste an existing URL into a prompt to automatically recreate its layout, styling, and structure—producing a near‑perfect clone of a site in very little time.

The history of the imposter domain tells an incremental evolution into abuse.

Registered in 2019, the site did not initially contain any Malwarebytes branding. In 2022, the operator began layering in Malwarebytes branding while publishing Indonesian‑language security content. This likely helped with search reputation while normalizing the brand look to visitors. Later, the site went blank, with no public archive records for 2025, only to resurface as a full-on clone backed by AI‑assisted tooling.​

Traffic did not arrive by accident. Links to the site appeared in comment spam and injected links on unrelated websites, giving users the impression of organic references and driving them toward the fake download pages.

Payment flows were equally opaque. The fake site used PayPal for payments, but the integration hid the merchant’s name and logo from the user-facing confirmation screens, leaving only the buyer’s own details visible. That allowed the criminals to accept money while revealing as little about themselves as possible.

Behind the scenes, historical registration data pointed to an origin in India and to a hosting IP (209.99.40[.]222) associated with domain parking and other dubious uses rather than normal production hosting.

Combined with the AI‑powered cloning and the evasive payment configuration, it painted a picture of low‑effort, high‑confidence fraud.

AI website builders as force multipliers

The installmalwarebytes[.]org case is not an isolated misuse of AI‑assisted builders. It fits into a broader pattern of attackers using generative tools to create and host phishing sites at scale.

Threat intelligence teams have documented abuse of Vercel’s v0 platform to generate fully functional phishing pages that impersonate sign‑in portals for a variety of brands, including identity providers and cloud services, all from simple text prompts. Once the AI produces a clone, criminals can tweak a few links to point to their own credential‑stealing backends and go live in minutes.

Research into AI’s role in modern phishing shows that attackers are leaning heavily on website generators, writing assistants, and chatbots to streamline the entire kill chain—from crafting persuasive copy in multiple languages to spinning up responsive pages that render cleanly across devices. One analysis of AI‑assisted phishing campaigns found that roughly 40% of observed abuse involved website generation services, 30% involved AI writing tools, and about 11% leveraged chatbots, often in combination. This stack lets even low‑skilled actors produce professional-looking scams that used to require specialized skills or paid kits.​

Growth first, guardrails later

The core problem is not that AI can build websites. It’s that the incentives around AI platform development are skewed. Vendors are under intense pressure to ship new capabilities, grow user bases, and capture market share, and that pressure often runs ahead of serious investment in abuse prevention.

As Malwarebytes General Manager Mark Beare put it:

“AI-powered website builders like Lovable and Vercel have dramatically lowered the barrier for launching polished sites in minutes. While these platforms include baseline security controls, their core focus is speed, ease of use, and growth—not preventing brand impersonation at scale. That imbalance creates an opportunity for bad actors to move faster than defenses, spinning up convincing fake brands before victims or companies can react.”

Site generators allow cloned branding of well‑known companies with no verification, publishing flows skip identity checks, and moderation either fails quietly or only reacts after an abuse report. Some builders let anyone spin up and publish a site without even confirming an email address, making it easy to burn through accounts as soon as one is flagged or taken down.

To be fair, there are signs that some providers are starting to respond by blocking specific phishing campaigns after disclosure or by adding limited brand-protection controls. But these are often reactive fixes applied after the damage is done.

Meanwhile, attackers can move to open‑source clones or lightly modified forks of the same tools hosted elsewhere, where there may be no meaningful content moderation at all.

In practice, the net effect is that AI companies benefit from the growth and experimentation that comes with permissive tooling, while the consequences is left to victims and defenders.

We have blocked the domain in our web protection module and requested a domain and vendor takedown.

How to stay safe

End users cannot fix misaligned AI incentives, but they can make life harder for brand impersonators. Even when a cloned website looks convincing, there are red flags to watch for:

• Before completing any payment, always review the “Pay to” details or transaction summary. If no merchant is named, back out and treat the site as suspicious.
• Use an up-to-date, real-time anti-malware solution with a web protection module.
• Do not follow links posted in comments, on social media, or unsolicited emails to buy a product. Always follow a verified and trusted method to reach the vendor.

If you come across a fake Malwarebytes website, please let us know.

As the agentic era reshapes security operations, leaders face a strategic inflection point: legacy security information and event management (SIEM) solutions and fragmented toolchains can no longer keep pace with the scale, speed, and complexity of modern cyberthreats. Organizations can choose to spend the next year tuning and integrating their SIEM stack—or simplify the architecture and let a unified platform do the heavy lifting. If they choose a platform, it should make it inexpensive to ingest and retain more telemetry, automatically shape that data into analysis‑ready form, and enrich it with graph‑driven intelligence so both analysts and AI can quickly understand what matters and why. The strategic SIEM buyer’s guide outlines what decision‑makers should look for as they build a future‑ready security operations center (SOC). Read on for a preview of key concepts covered in the guide.

Build a unified, future-proof foundation

As organizations step into the agentic AI era, the priority shifts to establishing a security foundation that can absorb rapid change without adding operational drag. That requires an architecture built for flexibility—one that brings security data, analytics, and response capabilities together rather than scattering them across aging infrastructure. A unified, cloud‑native platform gives security teams the structural advantage of consistent visibility, elastic scale, and a single source of truth for both human analysts and AI systems. By consolidating core functions into one environment, leaders can modernize the SOC in a deliberate, sustainable way while positioning their teams to capitalize on emerging AI‑powered security capabilities.

Accelerate detection and response with AI

As cyberthreats evolve faster than traditional workflows can manage, the advantage shifts to SOCs that can elevate detection and response with adaptive automation. Modern platforms augment analysts with real‑time correlation, automated investigation, and adaptive orchestration that reduces manual steps and shortens exposure windows. By standardizing access to high‑quality security data and enabling agents to act on that context, organizations improve precision, reduce noise, and transition from reactive triage to continuous, intelligence‑driven response. This shift not only accelerates outcomes but frees teams to focus on higher‑value threat hunting and strategic risk reduction.

Maximize return on investment and accelerate time to value

Driving measurable value is now a leadership imperative, and modern SIEM platforms must deliver results without protracted deployments or heavy reliance on specialized expertise. AI-ready solutions reduce onboarding friction through prebuilt connectors, embedded analytics, and turnkey content that produce meaningful detection coverage within hours—not months.

“Microsoft Sentinel’s ease of use means we can go ahead and deploy our solutions much faster. It means we can get insights into how things are operating more quickly.”

—Director of IT in the healthcare industry

By consolidating core workflows into a single environment, organizations avoid the hidden costs of operating multiple tools and shorten the path from implementation to impact. As adaptive AI optimizes configurations, prioritizes coverage gaps, and streamlines operations, security leaders gain a clearer return on investment while reallocating resources toward strategic risk reduction instead of maintenance and integration work. AI‑ready solutions reduce onboarding friction through pre‑built connectors, embedded analytics, and turnkey content that produce meaningful detection coverage within hours—not months.

Turning guidance into action with Microsoft

The guide also outlines where Microsoft Sentinel delivers meaningful advantages for modern SOC leaders—from its cloud‑native scale and unified data foundation to integrated SIEM, security orchestration, automation, and response (SOAR), extended detection and response (XDR), and advanced analytics in a single AI‑ready platform. It includes practical tips for evaluating vendors, highlighting the importance of unification, cloud‑native elasticity, and avoiding fragmented add‑ons that drive hidden costs. Together, the three essentials—building a unified foundation, accelerating detection and response with AI, and maximizing return on investment through rapid time to value—establish a clear roadmap for modernizing security operations.

As Valentine’s Day 2026 approaches, people are turning to online shopping, digital dating, and last‑minute gift ideas. Unfortunately, cyber criminals are doing the same. Check Point researchers have identified a sharp rise in Valentine‑themed phishing websites, fraudulent stores, and fake dating platforms designed to steal personal data and payment information. A Seasonal Spike in Valentine-Themed Domains From March to December 2025, new Valentine-related domains averaged 474 per month. But in January 2026, registrations jumped to 696 — a 44% increase. In just the first five days of February, researchers detected 152 additional domains, a further 36% rise in daily average […]

We often describe cases of malware distribution under the guise of game cheats and pirated software. Sometimes such methods are used to spread complex malware that employs advanced techniques and sophisticated infection chains.

In February 2026, researchers from Howler Cell announced the discovery of a mass campaign distributing pirated games infected with a previously unknown family of malware. It turned out to be a loader called RenEngine, which was delivered to the device using a modified version of the Ren’Py engine-based game launcher. Kaspersky solutions detect the RenEngine loader as Trojan.Python.Agent.nb and HEUR:Trojan.Python.Agent.gen.

However, this threat is not new. Our solutions began detecting the first samples of the RenEngine loader in March 2025, when it was used to distribute the Lumma stealer (Trojan-PSW.Win32.Lumma.gen).

In the ongoing incidents, ACR Stealer (Trojan-PSW.Win32.ACRstealer.gen) is being distributed as the final payload. We have been monitoring this campaign for a long time and will share some details in this article.

Incident analysis

Disguise as a visual novel

Let’s look at the first incident, which we detected in March 2025. At that time, the attackers distributed the malware under the guise of a hacked game on a popular gaming web resource.

The website featured a game download page with two buttons: Free Download Now and Direct Download. Both buttons had the same functionality: they redirected users to the MEGA file-sharing service, where they were offered to download an archive with the “game.”

When the “game” was launched, the download process would stop at 100%. One might think that the game froze, but that was not the case — the “real” malicious code just started working.

“Game” source files analysis

After analyzing the source files, we found Python scripts that initiated the initial device infection. These scripts imitated the endless loading of the game. In addition, they contained the is_sandboxed function for bypassing the sandbox and xor_decrypt_file for decrypting the malicious payload. Using the latter, the script decrypts the ZIP archive, unpacks its contents into the .temp directory, and launches the unpacked files.

There are five files in the .temp directory. The DKsyVGUJ.exe executable is not malicious. Its original name is Ahnenblatt4.exe, and it is a well-known legitimate application for organizing genealogical data. The borlndmm.dll library also does not contain malicious code; it implements the memory manager required to run the executable. Another library, cc32290mt.dll, contains a code snippet patched by attackers that intercepts control when the application is launched and deploys the first stage of the payload in the process memory.

HijackLoader

The dbghelp.dll system library is used as a “container” to launch the first stage of the payload. It is overwritten in memory with decrypted shellcode obtained from the gayal.asp file using the cc32290mt.dll library. The resulting payload is HijackLoader. This is a relatively new means of delivering and deploying malicious implants. A distinctive feature of this malware family is its modularity and configuration flexibility. HijackLoader was first detected and described in the summer of 2023. More detailed information about this loader is available to customers of the Kaspersky Intelligence Reporting Service.

The final payload can be delivered in two ways, depending on the configuration parameters of the malicious sample. The main HijackLoader ti module is used to launch and prepare the process for the final payload injection. In some cases, an additional module is also used, which is injected into an intermediate process launched by the main one. The code that performs the injection is the same in both cases.

Before creating a child process, the configuration parameters are encrypted using XOR and saved to the %TEMP% directory with a random name. The file name is written to the system environment variables.

In the analyzed sample, the execution follows a longer path with an intermediate child process, cmd.exe. It is created in suspended mode by calling the auxiliary module modCreateProcess. Then, using the ZwCreateSection and ZwMapViewOfSection system API calls, the code of the same dbghelp.dll library is loaded into the address space of the process, after which it intercepts control.

Next, the ti module, launched inside the child process, reads the hap.eml file, from which it decrypts the second stage of HijackLoader. The module then loads the pla.dll system library and overwrites the beginning of its code section with the received payload, after which it transfers control to this library.

The decrypted payload is an EXE file, and the configuration parameters are set to inject it into the explorer.exe child process. The payload is written to the memory of the child process in several stages:

1. First, the malicious payload is written to a temporary file on disk using the transaction mechanism provided by the Windows API. The payload is written in several stages and not in the order in which the data is stored in the file. The MZ signature, with which any PE file begins, is written last with a delay.
   
   

   Writing the payload to a temporary file

2. After that, the payload is loaded from the temporary file into the address space of the current process using the ZwCreateSection call. The transaction that wrote to the file is rolled back, thus deleting the temporary file with the payload.
3. Next, the sample uses the modCreateProcess module to launch the child process explorer.exe and injects the payload into it by creating a shared memory region with the ZwMapViewOfSection call.
   
   

   Payload injection into the child process

   
   Another HijackLoader module, rshell, is used to launch the shellcode. Its contents are also injected into the child process, replacing the code located at its entry point.
   
   

   The rshell module injection

4. The last step performed by the parent process is starting a thread in the child process by calling ZwResumeThread. After that, the thread starts executing the rshell module code placed at the child process entry point, and the parent process terminates.

   The rshell module prepares the final malicious payload. Once it has finished, it transfers control to another HijackLoader module called ESAL. It replaces the contents of rshell with zeros using the memset function and launches the final payload, which is a stealer from the Lumma family (Trojan-PSW.Win32.Lumma).

In addition to the modules described above, this HijackLoader sample contains the following modules, which were used at intermediate stages: COPYLIST, modTask, modUAC, and modWriteFile.
Kaspersky solutions detect HijackLoader with the verdicts Trojan.Win32.Penguish and Trojan.Win32.DllHijacker.

Not only games

In addition to gaming sites, we found that attackers created dozens of different web resources to distribute RenEngine under the guise of pirated software. On one such site, for example, users can supposedly download an activated version of the CorelDRAW graphics editor.

When the user clicks the Descargar Ahora (“Download Now”) button, they are redirected several times to other malicious websites, after which an infected archive is downloaded to their device.

Distribution

According to our data, since March 2025, RenEngine has affected users in the following countries:

Distribution of incidents involving the RenEngine loader by country (TOP 20), February 2026 (download)

The distribution pattern of this loader suggests that the attacks are not targeted. At the time of publication, we have recorded the highest number of incidents in Russia, Brazil, Türkiye, Spain, and Germany.

Recommendations for protection

The format of game archives is generally not standardized and is unique for each game. This means that there is no universal algorithm for unpacking and checking the contents of game archives. If the game engine does not check the integrity and authenticity of executable resources and scripts, such an archive can become a repository for malware if modified by attackers. Despite this, Kaspersky Premium protects against such threats with its Behavior Detection component.

The distribution of malware under the guise of pirated software and hacked games is not a new tactic. It is relatively easy to avoid infection by the malware described in this article: simply install games and programs from trusted sites. In addition, it is important for gamers to remember the need to install specialized security solutions. This ongoing campaign employs the Lumma and ACR stylers, and Vidar was also found — none of these are new threats, but rather long-known malware. This means that modern antivirus technologies can detect even modified versions of the above-mentioned stealers and their alternatives, preventing further infection.

The Detection Engineering Baseline: Hypothesis and Structure (Part 1) by Brandon Lyons

Baselining is an overused term in this field because, at least in my experience, it’s a hand-wavy marketing term. You’ll read about a product that’ll perform baselines of your behavior and environment, and it’ll alert you if it detects something abnormal or outside that baseline. In practice, this works, but the opaqueness of some of these methods makes it hard to understand how it happens.

This is why posts like Lyons help cut through the opaqueness and show the receipts of how to do this in practice. And to be honest, it’s nothing groundbreaking, only in the sense that the concepts Lyons proposes here are part of entry-level statistics literacy. Which is why I’m pretty opinionated on the engineer of detection engineer. Don’t get it twisted: although the concepts in this post are entry-level statistics, understanding the application requires deep security expertise.

Lyons lays out a 7-step, repeatable process to establish a detection baseline, quoted here:

• Backtesting of rule logic: Validate your detection against historical data before deploying

• Codified thought process: Document why you chose specific thresholds and methods

• Historical context: Capture what your environment looked like when the baseline was created

• Reproducible process: Enable re-running when tuning or validating detection logic

• Foundation for the ADS: Feed directly into your Alerting Detection Strategy documentation

• Cross-team collaboration fuel: Surface insecure patterns and workflows with data-backed evidence

• Threat hunting runway: When alert precision isn’t achievable, convert the baseline into a scheduled hunt

This process succinctly captures a well-thought-out detection process. Without data, how can anyone possibly deploy detections that will fire? Without context around that data, how can anyone possibly believe the rules that are firing outside of the baseline?

They step through the 7 steps here using a CloudTrail API example. Basically, Lyons tries to map out what anomalous behavior looks like for CloudTrail access across an environment. The statistics section focuses on a modified Z-Score. Here’s the rundown:

Security metrics (API calls per day, login attempts per hour, file accesses) approximate a normal distribution (a bell curve), especially when aggregated over time. This means that:

• Most values cluster around the median (middle value)

• Extreme values become increasingly rare as you move away from the center

• The distribution is symmetric

To establish a baseline, Lyons collects historical data, such as 30 days of activity, and computes two key statistics:

• Median - the middle value

• MAD (Median Absolute Deviation) - measures spread around the median

When a new value enters your queue, you compute the Modified Z-score, which is the distance-via-standard-deviation of that value from the median. Modified Z-score is really good at capturing outliers, versus the regular Z-score, which focuses on standard deviations from the mean, and can be sensitive to outliers.

An outlier can be, according to Lyons, creating administrative credentials at 3am to an abnormal amount of S3 bucket accesses, perhaps used for exfiltration. Here’s a graphic I prompted Claude to create to drive this point home:

This type of rigor removes the guessing game about whether events are absolute measurements. Is 1000 API calls weird, or is 100? Is 10 pm an acceptable window for Administrator access, or is 5 pm? By looking at the standard deviations away from the median, you focus on relative measurement. It removes the human judgment about the absolute weirdness of an event, and whenever you remove a human from a large data problem, you get a bit closer to sanity.

Lyons created a follow-along Jupyter notebook with synthetic data to recreate the measurements in his blog. I’ll link that repository below in the Open Source section!

Building a Production-Ready Snowflake Audit Log Pipeline to S3 by xcal

Centralizing logs to your SIEM is a full-time endeavor, and requires expertise in so many areas, such as:

• Data formats of the logs you are extracting, transforming, and loading into the SIEM

• Telemetry source peculiarities, such as APIs, subsystems on hosts, or weird licensing issues

• Choosing a technology stack that can normalize logs and send them into the SIEM

• Navigating technological barriers due to inherent design choices, especially between data lakes or SaaS products

This is why I really enjoyed reading this post about moving audit log data from Snowflake into a SIEM. It focuses on the software engineering component of detection engineering, because many of the design choices made inside this post are things that you’ll hear about on a Software Engineering interview.

The first half of this blog details the design choices behind moving data from Snowflake to S3 and then to a SIEM, with clear architectural “gotchas” you need to design around. The most interesting one to me is the watermark strategy.

Snowflake audit logs have built-in latency. An event can occur at 12:00, but the audit log does not appear until 12:03. You use a watermark to pull the oldest events up to the last event you saw. For example, a watermark of 12:00 means you processed events up to 11:59. This watermark doesn’t work if you focus only on the timestamp generated, so you try to use it to focus on what you’ve observed.

In the purple example, 3 export runs for logs came in, and the watermark is updated based on the export time. When the “late arrival” log comes in, the watermark is later than the data's arrival time, so the log is lost forever. In the second yellow example, this is fixed by looking at the maximum observed time in the logs, not at the time the export is run.

What’s beautiful about this blog, too, is how it sets up a “configuration-as-data” design pattern. They use a statically stored procedure for the export logic and a table that maps the target View, such as SESSION or LOGIN, to the timestamp used to perform the watermark.

This design choice makes it easy to add more views, VIEW_NAME, specify a target timestamp, TS_COLUMN_NAME, then store the watermark in LAST_TS. A singular INSERT into the EXPORT_WATERMARK table adds additional Audit logs views to export, without changing the code.

Detection Rule Fragility: Design Pitfalls Every Detection Engineer Must Know by SOCLabs

Detection rule fragility occurs when your rules become too precise for a single detection scenario and miss variants that achieve the same outcome. In this post, SOCLabs details several “gotcha” scenarios on the command line where classic detection on strings can be circumvented by operating-system-level trickery.

My favorite examples they list involve URL detection with cURL. There’s something about the concept of URL parsing that is so fascinating on the operating system level, because it’s a little known attack path that can have some hilarious results. For example, if you want some light reading, check out RFC3986 - Uniform Resource Identifier (URI): Generic Syntax.

Let’s say you write a rule to detect a local IP address, such as http://192.168.x.x Your operating system and browser parses it, and can navigate to it, so you write a rule to detect local subnet usage in cURL. But you can also write http://192.168. as hex, http://0xC0.0xA, or even octal, http://0300.0250. So, did you write a rule for those? :)

How I Use LLMs for Security Work by Josh Rickard

This is a cool, battle-tested approach by Rickard for prompting an LLM to do security work. I think people can become overwhelmed by what to prompt an LLM, because they are generally really good at taking vanilla prompt sessions and running with whatever work you assign them. But, as your work gets more complex, there are some nifty strategies you can use, and Rickard lays out, to make the best use of what they have to offer.

Giving context is probably the biggest takeaway here, so Rickard describes the concept of role-stacking, explains your technology stack, clarifies the current understanding of the ask, and gives it time to execute the ask.

What AI Really Looks Like Inside the SOC: Notes from a Fireside Chat by Daniel Santiago

In this post, Santiago shares his notes around a SOC fireside chat they attended during a Simply Cyber event. The cool part of his synopsis was seeing the “ground reality” of AI working and not working in a SOC environment. Most of the insights aren’t surprising to me, but it’s good to hear it validate some of our feelings. For example, Santiago points out how these agents raise the baseline for analysts, rather than replace them.

The GTIG group published a large survey of threats they are tracking against Defense firms and organizations, such as contractors, critical infrastructure and government entities. They have four large takeaways and specify which threat actor groups are part of these takeaways:

• Targeting of critical infrastructure by Russian-nexus threat actor groups to introduce physical and security effects

• Hiring of fake IT Workers and DPRK’s focus on espionage using IT workers and malware campaigns

• China-nexus threat actors representing the largest campaigns targeting these sectors by volume

• An uptick of data leak sites and extortion groups against manufacturing firms that may supply the defense industrial base

VoidLink: Dissecting an AI-Generated C2 Implant by Rhys Downing

VoidLink is a post-exploitation and implant framework that focuses on cloud-native infrastructure. It was in the headlines around a month ago, and the main headline was that it was likely LLM-generated. Downing pulled apart the payloads and tried to confirm this finding, so it’s nice to see proof rather than believing the hype. The fun part is that within the binary, several clues suggested it was LLM-generated, primarily in the code comments.

According to Downing, and I tend to agree here, adding comments to your malware seems like a rookie move because you want operational security and anti-research capabilities, so this likely suggests it’s LLM-generated and the operators were careless.

New Clickfix variant ‘CrashFix’ deploying Python Remote Access Trojan by Microsoft Defender Security Research Team

Microsoft Security Research uncovered a new style of ClickFix social engineering techniques, dubbed CrashFix. When a victim is funneled to the malicious site, they are tricked to thinking their computer is crashing, and are directed to run the malicious payload.

The rest of the campaign is well-researched, but nothing particularly different from other ClickFix and infostealer campaigns. I imagine we’ll continue to see these social engineering threats evolve until we blow up command-line access for people and move to something else. Perhaps Claude Cowork social engineering?

Malicious use of virtual machine infrastructure by Sophos Counter Threat Unit Research Team

This piece by the Sophos Threat Research Team began with a security incident in which they uncovered attacker infrastructure with unique Windows hostnames. When the team dug into these hostnames, they found they were out-of-the-box names from a legitimate IT provider, ISPSystem. At first, it seemed like a single actor was leveraging ISPSystem to quickly deploy infrastructure, but when the team pivoted to Shodan, they found several thousand instances of ISPSystem infrastructure in use across many different malware campaigns.

Windows hostnames are a cool pivot that I haven’t really seen much of in my years of threat research. This worked in Sophos’ favor because it’s virtual machine software that offers some ease of use for several threat actor groups.

This is a clever technique that abuses Windows ProjFS. ProjFS allows processes to project filesystems based on several attributes, so it’s used for things like OneDrive where you connect out to a drive hosted on a cloud provider. S1lkys built this in a way that it’ll project an encrypted payload, like Mimikatz, if it detects a source process coming from the command line versus EDR tools.

wardgate/wardgate

Wardgate is an Agentic proxy that stores secrets and API keys on your agent’s behalf. The idea here is that the Agent is aware it has API access to some external service, you have it use Wardgate, and Wardgate will serve as the API proxy. This is especially helpful if you are afraid of attacks on Agents that steal local or cached credentials.

Phishing and scams in 2025

Entertainment-themed phishing attacks and scams

In 2025, online streaming services remained a primary theme for phishing sites within the entertainment sector, typically by offering early access to major premieres ahead of their official release dates. Alongside these, there was a notable increase in phishing pages mimicking ticket aggregation platforms for live events. Cybercriminals lured users with offers of free tickets to see popular artists on pages that mirrored the branding of major ticket distributors. To participate in these “promotions”, victims were required to pay a nominal processing or ticket-shipping fee. Naturally, after paying the fee, the users never received any tickets.

In addition to concert-themed bait, other music-related scams gained significant traction. Users were directed to phishing pages and prompted to “vote for their favorite artist”, a common activity within fan communities. To bolster credibility, the scammers leveraged the branding of major companies like Google and Spotify. This specific scheme was designed to harvest credentials for multiple platforms simultaneously, as users were required to sign in with their Facebook, Instagram, or email credentials to participate.

As a pretext for harvesting Spotify credentials, attackers offered users a way to migrate their playlists to YouTube. To complete the transfer, victims were to just enter their Spotify credentials.

Beyond standard phishing, threat actors leveraged Spotify’s popularity for scams. In Brazil, scammers promoted a scheme where users were purportedly paid to listen to and rate songs.

To “withdraw” their earnings, users were required to provide their identification number for PIX, Brazil’s instant payment system.

Users were then prompted to verify their identity. To do so, the victim was required to make a small, one-time “verification payment”, an amount significantly lower than the potential earnings.

The form for submitting this “verification payment” was designed to appear highly authentic, even requesting various pieces of personal data. It is highly probable that this data was collected for use in subsequent attacks.

In another variation, users were invited to participate in a survey in exchange for a $1000 gift card. However, in a move typical of a scam, the victim was required to pay a small processing or shipping fee to claim the prize. Once the funds were transferred, the attackers vanished, and the website was taken offline.

Even deciding to go to an art venue with a girl from a dating site could result in financial loss. In this scenario, the “date” would suggest an in-person meeting after a brief period of rapport-building. They would propose a relatively inexpensive outing, such as a movie or a play at a niche theater. The scammer would go so far as to provide a link to a specific page where the victim could supposedly purchase tickets for the event.

To enhance the site’s perceived legitimacy, it even prompted the user to select their city of residence.

However, once the “ticket payment” was completed, both the booking site and the individual from the dating platform would vanish.

A similar tactic was employed by scam sites selling tickets for escape rooms. The design of these pages closely mirrored legitimate websites to lower the target’s guard.

Phishing pages masquerading as travel portals often capitalize on a sense of urgency, betting that a customer eager to book a “last-minute deal” will overlook an illegitimate URL. For example, the fraudulent page shown below offered exclusive tours of Japan, purportedly from a major Japanese tour operator.

Sensitive data at risk: phishing via government services

To harvest users’ personal data, attackers utilized a traditional phishing framework: fraudulent forms for document processing on sites posing as government portals. The visual design and content of these phishing pages meticulously replicated legitimate websites, offering the same services found on official sites. In Brazil, for instance, attackers collected personal data from individuals under the pretext of issuing a Rural Property Registration Certificate (CCIR).

Through this method, fraudsters tried to gain access to the victim’s highly sensitive information, including their individual taxpayer registry (CPF) number. This identifier serves as a unique key for every Brazilian national to access private accounts on government portals. It is also utilized in national databases and displayed on personal identification documents, making its interception particularly dangerous. Scammer access to this data poses a severe risk of identity theft, unauthorized access to government platforms, and financial exposure.

Furthermore, users were at risk of direct financial loss: in certain instances, the attackers requested a “processing fee” to facilitate the issuance of the important document.

Fraudsters also employed other methods to obtain CPF numbers. Specifically, we discovered phishing pages mimicking the official government service portal, which requires the CPF for sign-in.

Another theme exploited by scammers involved government payouts. In 2025, Singaporean citizens received government vouchers ranging from $600 to $800 in honor of the country’s 60th anniversary. To redeem these, users were required to sign in to the official program website. Fraudsters rushed to create web pages designed to mimic this site. Interestingly, the primary targets in this campaign were Telegram accounts, despite the fact that Telegram credentials were not a requirement for signing in to the legitimate portal.

We also identified a scam targeting users in Norway who were looking to renew or replace their driver’s licenses. Upon opening a website masquerading as the official Norwegian Public Roads Administration website, visitors were prompted to enter their vehicle registration and phone numbers.

Next, the victim was prompted for sensitive data, such as the personal identification number unique to every Norwegian citizen. By doing so, the attackers not only gained access to confidential information but also reinforced the illusion that the victim was interacting with an official website.

Once the personal data was submitted, a fraudulent page would appear, requesting a “processing fee” of 1200 kroner. If the victim entered their credit card details, the funds were transferred directly to the scammers with no possibility of recovery.

In Germany, attackers used the pretext of filing tax returns to trick users into providing their email user names and passwords on phishing pages.

A call to urgent action is a classic tactic in phishing scenarios. When combined with the threat of losing property, these schemes become highly effective bait, distracting potential victims from noticing an incorrect URL or a poorly designed website. For example, a phishing warning regarding unpaid vehicle taxes was used as a tool by attackers targeting credentials for the UK government portal.

We have observed that since the spring of 2025, there has been an increase in emails mimicking automated notifications from the Russian government services portal. These messages were distributed under the guise of application status updates and contained phishing links.

We also recorded vishing attacks targeting users of government portals. Victims were prompted to “verify account security” by calling a support number provided in the email. To lower the users’ guard, the attackers included fabricated technical details in the emails, such as the IP address, device model, and timestamp of an alleged unauthorized sign-in.

Last year, attackers also disguised vishing emails as notifications from microfinance institutions or credit bureaus regarding new loan applications. The scammers banked on the likelihood that the recipient had not actually applied for a loan. They would then prompt the victim to contact a fake support service via a spoofed support number.

Know Your Customer

As an added layer of data security, many services now implement biometric verification (facial recognition, fingerprints, and retina scans), as well as identity document verification and digital signatures. To harvest this data, fraudsters create clones of popular platforms that utilize these verification protocols. We have previously detailed the mechanics of this specific type of data theft.

In 2025, we observed a surge in phishing attacks targeting users under the guise of Know Your Customer (KYC) identity verification. KYC protocols rely on a specific set of user data for identification. By spoofing the pages of payment services such as Vivid Money, fraudsters harvested the information required to pass KYC authentication.

Notably, this threat also impacted users of various other platforms that utilize KYC procedures.

A distinctive feature of attacks on the KYC process is that, in addition to the victim’s full name, email address, and phone number, phishers request photos of their passport or face, sometimes from multiple angles. If this information falls into the hands of threat actors, the consequences extend beyond the loss of account access; the victim’s credentials can be sold on dark web marketplaces, a trend we have highlighted in previous reports.

Messaging app phishing

Account hijacking on messaging platforms like WhatsApp and Telegram remains one of the primary objectives of phishing and scam operations. While traditional tactics, such as suspicious links embedded in messages, have been well-known for some time, the methods used to steal credentials are becoming increasingly sophisticated.

For instance, Telegram users were invited to participate in a prize giveaway purportedly hosted by a famous athlete. This phishing attack, which masqueraded as an NFT giveaway, was executed through a Telegram Mini App. This marks a shift in tactics, as attackers previously relied on external web pages for these types of schemes.

In 2025, new variations emerged within the familiar framework of distributing phishing links via Telegram. For example, we observed prompts inviting users to vote for the “best dentist” or “best COO” in town.

The most prevalent theme in these voting-based schemes, children’s contests, was distributed primarily through WhatsApp. These phishing pages showed little variety; attackers utilized a standardized website design and set of “bait” photos, simply localizing the language based on the target audience’s geographic location.

To participate in the vote, the victim was required to enter the phone number linked to their WhatsApp account.

They were then prompted to provide a one-time authentication code for the messaging app.

The following are several other popular methods used by fraudsters to hijack user credentials.

In China, phishing pages meticulously replicated the WhatsApp interface. Victims were notified that their accounts had purportedly been flagged for “illegal activity”, necessitating “additional verification”.

The victim was redirected to a page to enter their phone number, followed by a request for their authorization code.

In other instances, users received messages allegedly from WhatsApp support regarding account authentication via SMS. As with the other scenarios described, the attackers’ objective was to obtain the authentication code required to hijack the account.

Fraudsters enticed WhatsApp users with an offer to link an app designed to “sync communications” with business contacts.

To increase the perceived legitimacy of the phishing site, the attackers even prompted users to create custom credentials for the page.

After that, the user was required to “purchase a subscription” to activate the application. This allowed the scammers to harvest credit card data, leaving the victim without the promised service.

To lure Telegram users, phishers distributed invitations to online dating chats.

Attackers also heavily leveraged the promise of free Telegram Premium subscriptions. While these phishing pages were previously observed only in Russian and English, the linguistic scope of these campaigns expanded significantly this year. As in previous iterations, activating the subscription required the victim to sign in to their account, which could result in the loss of account access.

Exploiting the ChatGPT hype

Artificial intelligence is increasingly being leveraged by attackers as bait. For example, we have identified fraudulent websites mimicking the official payment page for ChatGPT Plus subscriptions.

Social media marketing through LLMs was also a potential focal point for user interest. Scammers offered “specialized prompt kits” designed for social media growth; however, once payment was received, they vanished, leaving victims without the prompts or their money.

The promise of easy income through neural networks has emerged as another tactic to attract potential victims. Fraudsters promoted using ChatGPT to place bets, promising that the bot would do all the work while the user collected the profits. These services were offered at a “special price” valid for only 15 minutes after the page was opened. This narrow window prevented the victim from critically evaluating the impulse purchase.

Job opportunities with a catch

To attract potential victims, scammers exploited the theme of employment by offering high-paying remote positions. Applicants responding to these advertisements did more than just disclose their personal data; in some cases, fraudsters requested a small sum under the pretext of document processing or administrative fees. To convince victims that the offer was legitimate, attackers impersonated major brands, leveraging household names to build trust. This allowed them to lower the victims’ guard, even when the employment terms sounded too good to be true.

We also observed schemes where, after obtaining a victim’s data via a phishing site, scammers would follow up with a phone call – a tactic aimed at tricking the user into disclosing additional personal data.

By analyzing current job market trends, threat actors also targeted popular career paths to steal messaging app credentials. These phishing schemes were tailored to specific regional markets. For example, in the UAE, fake “employment agency” websites were circulating.

In a more sophisticated variation, users were asked to complete a questionnaire that required the phone number linked to their Telegram account.

To complete the registration, users were prompted for a code which, in reality, was a Telegram authorization code.

Notably, the registration process did not end there; the site continued to request additional information to “set up an account” on the fraudulent platform. This served to keep victims in the dark, maintaining their trust in the malicious site’s perceived legitimacy.

After finishing the registration, the victim was told to wait 24 hours for “verification”, though the scammers’ primary objective, hijacking the Telegram account, had already been achieved.

Simpler phishing schemes were also observed, where users were redirected to a page mimicking the Telegram interface. By entering their phone number and authorization code, victims lost access to their accounts.

Job seekers were not the only ones targeted by scammers. Employers’ accounts were also in the crosshairs, specifically on a major Russian recruitment portal. On a counterfeit page, the victim was asked to “verify their account” in order to post a job listing, which required them to enter their actual sign-in credentials for the legitimate site.

Spam in 2025

Malicious attachments

Password-protected archives

Attackers began aggressively distributing messages with password-protected malicious archives in 2024. Throughout 2025, these archives remained a popular vector for spreading malware, and we observed a variety of techniques designed to bypass security solutions.

For example, threat actors sent emails impersonating law firms, threatening victims with legal action over alleged “unauthorized domain name use”. The recipient was prompted to review potential pre-trial settlement options detailed in an attached document. The attachment consisted of an unprotected archive containing a secondary password-protected archive and a file with the password. Disguised as a legal document within this inner archive was a malicious WSF file, which installed a Trojan into the system via startup. The Trojan then stealthily downloaded and installed Tor, which allowed it to regularly exfiltrate screenshots to the attacker-controlled C2 server.

In addition to archives, we also encountered password-protected PDF files containing malicious links over the past year.

E-signature service exploits

Emails using the pretext of “signing a document” to coerce users into clicking phishing links or opening malicious attachments were quite common in 2025. The most prevalent scheme involved fraudulent notifications from electronic signature services. While these were primarily used for phishing, one specific malware sample identified within this campaign is of particular interest.

The email, purportedly sent from a well-known document-sharing platform, notified the recipient that they had been granted access to a “contract” attached to the message. However, the attachment was not the expected PDF; instead, it was a nested email file named after the contract. The body of this nested message mirrored the original, but its attachment utilized a double extension: a malicious SVG file containing a Trojan was disguised as a PDF document. This multi-layered approach was likely an attempt to obfuscate the malware and bypass security filters.

“Business correspondence” impersonating industrial companies

In the summer of last year, we observed mailshots sent in the name of various existing industrial enterprises. These emails contained DOCX attachments embedded with Trojans. Attackers coerced victims into opening the malicious files under the pretext of routine business tasks, such as signing a contract or drafting a report.

The authors of this malicious campaign attempted to lower users’ guard by using legitimate industrial sector domains in the “From” address. Furthermore, the messages were routed through the mail servers of a reputable cloud provider, ensuring the technical metadata appeared authentic. Consequently, even a cautious user could mistake the email for a genuine communication, open the attachment, and compromise their device.

Attacks on hospitals

Hospitals were a popular target for threat actors this past year: they were targeted with malicious emails impersonating well-known insurance providers. Recipients were threatened with legal action regarding alleged “substandard medical services”. The attachments, described as “medical records and a written complaint from an aggrieved patient”, were actually malware. Our solutions detect this threat as Backdoor.Win64.BrockenDoor, a backdoor capable of harvesting system information and executing malicious commands on the infected device.

We also came across emails with a different narrative. In those instances, medical staff were requested to facilitate a patient transfer from another hospital for ongoing observation and treatment. These messages referenced attached medical files containing diagnostic and treatment history, which were actually archives containing malicious payloads.

To bolster the perceived legitimacy of these communications, attackers did more than just impersonate famous insurers and medical institutions; they registered look-alike domains that mimicked official organizations’ domains by appending keywords such as “-insurance” or “-med.” Furthermore, to lower the victims’ guard, scammers included a fake “Scanned by Email Security” label.

Messages containing instructions to run malicious scripts

Last year, we observed unconventional infection chains targeting end-user devices. Threat actors continued to distribute instructions for downloading and executing malicious code, rather than attaching the malware files directly. To convince the recipient to follow these steps, attackers typically utilized a lure involving a “critical software update” or a “system patch” to fix a purported vulnerability. Generally, the first step in the instructions required launching the command prompt with administrative privileges, while the second involved entering a command to download and execute the malware: either a script or an executable file.

In some instances, these instructions were contained within a PDF file. The victim was prompted to copy a command into PowerShell that was neither obfuscated nor hidden. Such schemes target non-technical users who would likely not understand the command’s true intent and would unknowingly infect their own devices.

Scams

Law enforcement impersonation scams in the Russian web segment

In 2025, extortion campaigns involving actors posing as law enforcement – a trend previously more prevalent in Europe – were adapted to target users across the Commonwealth of Independent States.

For example, we identified messages disguised as criminal subpoenas or summonses purportedly issued by Russian law enforcement agencies. However, the specific departments cited in these emails never actually existed. The content of these “summonses” would also likely raise red flags for a cautious user. This blackmail scheme relied on the victim, in their state of panic, not scrutinizing the contents of the fake summons.

To intimidate recipients, the attackers referenced legal frameworks and added forged signatures and seals to the “subpoenas”. In reality, neither the cited statutes nor the specific civil service positions exist in Russia.

We observed similar attacks – employing fabricated government agencies and fictitious legal acts – in other CIS countries, such as Belarus.

Fraudulent investment schemes

Threat actors continued to aggressively exploit investment themes in their email scams. These emails typically promise stable, remote income through “exclusive” investment opportunities. This remains one of the most high-volume and adaptable categories of email scams. Threat actors embedded fraudulent links both directly within the message body and inside various types of attachments: PDF, DOC, PPTX, and PNG files. Furthermore, they increasingly leveraged legitimate Google services, such as Google Docs, YouTube, and Google Forms, to distribute these communications. The link led to the site of the “project” where the victim was prompted to provide their phone number and email. Subsequently, users were invited to invest in a non-existent project.

We have previously documented these mailshots: they were originally targeted at Russian-speaking users and were primarily distributed under the guise of major financial institutions. However, in 2025, this investment-themed scam expanded into other CIS countries and Europe. Furthermore, the range of industries that spammers impersonated grew significantly. For instance, in their emails, attackers began soliciting investments for projects supposedly led by major industrial-sector companies in Kazakhstan and the Czech Republic.

Fraudulent “brand partner” recruitment

This specific scam operates through a multi-stage workflow. First, the target company receives a communication from an individual claiming to represent a well-known global brand, inviting them to register as a certified supplier or business partner. To bolster the perceived authenticity of the offer, the fraudsters send the victim an extensive set of forged documents. Once these documents are signed, the victim is instructed to pay a “deposit”, which the attackers claim will be fully refunded once the partnership is officially established.

These mailshots were first detected in 2025 and have rapidly become one of the most prevalent forms of email-based fraud. In December 2025 alone, we blocked over 80,000 such messages. These campaigns specifically targeted the B2B sector and were notable for their high level of variation – ranging from their technical properties to the diversity of the message content and the wide array of brands the attackers chose to impersonate.

Fraudulent overdue rent notices

Last year, we identified a new theme in email scams: recipients were notified that the payment deadline for a leased property had expired and were urged to settle the “debt” immediately. To prevent the victim from sending funds to their actual landlord, the email claimed that banking details had changed. The “debtor” was then instructed to request the new payment information – which, of course, belonged to the fraudsters. These mailshots primarily targeted French-speaking countries; however, in December 2025, we discovered a similar scam variant in German.

QR codes in scam letters

In 2025, we observed a trend where QR codes were utilized not only in phishing attempts but also in extortion emails. In a classic blackmail scam, the user is typically intimidated by claims that hackers have gained access to sensitive data. To prevent the public release of this information, the attackers demand a ransom payment to their cryptocurrency wallet.

Previously, to bypass email filters, scammers attempted to obfuscate the wallet address by using various noise contamination techniques. In last year’s campaigns, however, scammers shifted to including a QR code that contained the cryptocurrency wallet address.

News agenda

As in previous years, spammers in 2025 aggressively integrated current events into their fraudulent messaging to increase engagement.

For example, following the launch of $TRUMP memecoins surrounding Donald Trump’s inauguration, we identified scam campaigns promoting the “Trump Meme Coin” and “Trump Digital Trading Cards”. In these instances, scammers enticed victims to click a link to claim “free NFTs”.

We also observed ads offering educational credentials. Spammers posted these ads as comments on legacy, unmoderated forums; this tactic ensured that notifications were automatically pushed to all users subscribed to the thread. These notifications either displayed the fraudulent link directly in the comment preview or alerted users to a new post that redirected them to spammers’ sites.

In the summer, when the wedding of Amazon founder Jeff Bezos became a major global news story, users began receiving Nigerian-style scam messages purportedly from Bezos himself, as well as from his former wife, MacKenzie Scott. These emails promised recipients substantial sums of money, framed either as charitable donations or corporate compensation from Amazon.

During the BLACKPINK world tour, we observed a wave of spam advertising “luggage scooters”. The scammers claimed these were the exact motorized suitcases used by the band members during their performances.

Finally, in the fall of 2025, traditionally timed to coincide with the launch of new iPhones, we identified scam campaigns featuring surveys that offered participants a chance to “win” a fictitious iPhone 17 Pro.

After completing a brief survey, the user was prompted to provide their contact information and physical address, as well as pay a “delivery fee” – which was the scammers’ ultimate objective. Upon entering their credit card details into the fraudulent site, the victim risked losing not only the relatively small delivery charge but also the entire balance in their bank account.

The widespread popularity of Ozempic was also reflected in spam campaigns; users were bombarded with offers to purchase versions of the drug or questionable alternatives.

Localized news events also fall under the scrutiny of fraudsters, serving as the basis for scam narratives. For instance, last summer, coinciding with the opening of the tax season in South Africa, we began detecting phishing emails impersonating the South African Revenue Service (SARS). These messages notified taxpayers of alleged “outstanding balances” that required immediate settlement.

Methods of distributing email threats

Google services

In 2025, threat actors increasingly leveraged various Google services to distribute email-based threats. We observed the exploitation of Google Calendar: scammers would create an event containing a WhatsApp contact number in the description and send an invitation to the target. For instance, companies received emails regarding product inquiries that prompted them to move the conversation to the messaging app to discuss potential “collaboration”.

Spammers employed a similar tactic using Google Classroom. We identified samples offering SEO optimization services that likewise directed victims to a WhatsApp number for further communication.

We also detected the distribution of fraudulent links via legitimate YouTube notifications. Attackers would reply to user comments under various videos, triggering an automated email notification to the victim. This email contained a link to a video that displayed only a message urging the viewer to “check the description”, where the actual link to the scam site was located. As the victim received an email containing the full text of the fraudulent comment, they were often lured through this chain of links, eventually landing on the scam site.

Over the past two years or so, there has been a significant rise in attacks utilizing Google Forms. Fraudsters create a survey with an enticing title and place the scam messaging directly in the form’s description. They then submit the form themselves, entering the victims’ email addresses into the field for the respondent email. This triggers legitimate notifications from the Google Forms service to the targeted addresses. Because these emails originate from Google’s own mail servers, they appear authentic to most spam filters. The attackers rely on the victim focusing on the “bait” description containing the fraudulent link rather than the standard form header.

Google Groups also emerged as a popular tool for spam distribution last year. Scammers would create a group, add the victims’ email addresses as members, and broadcast spam through the service. This scheme proved highly effective: even if a security solution blocked the initial spam message, the user could receive a deluge of automated replies from other addresses on the member list.

At the end of 2025, we encountered a legitimate email in terms of technical metadata that was sent via Google and contained a fraudulent link. The message also included a verification code for the recipient’s email address. To generate this notification, scammers filled out the account registration form in a way that diverted the recipient’s attention toward a fraudulent site. For example, instead of entering a first and last name, the attackers inserted text such as “Personal Link” followed by a phishing URL, utilizing noise contamination techniques. By entering the victim’s email address into the registration field, the scammers triggered a legitimate system notification containing the fraudulent link.

OpenAI

In addition to Google services, spammers leveraged other platforms to distribute email threats, notably OpenAI, riding the wave of artificial intelligence popularity. In 2025, we observed emails sent via the OpenAI platform into which spammers had injected short messages, fraudulent links, or phone numbers.

This occurs during the account registration process on the OpenAI platform, where users are prompted to create an organization to generate an API key. Spammers placed their fraudulent content directly into the field designated for the organization’s name. They then added the victims’ email addresses as organization members, triggering automated platform invitations that delivered the fraudulent links or contact numbers directly to the targets.

Spear phishing and BEC attacks in 2025

QR codes

The use of QR codes in spear phishing has become a conventional tactic that threat actors continued to employ throughout 2025. Specifically, we observed the persistence of a major trend identified in our previous report: the distribution of phishing documents disguised as notifications from a company’s HR department.

In these campaigns, attackers impersonated HR team members, requesting that employees review critical documentation, such as a new corporate policy or code of conduct. These documents were typically attached to the email as PDF files.

To maintain the ruse, the PDF document contained a highly convincing call to action, prompting the user to scan a QR code to access the relevant file. While attackers previously embedded these codes directly into the body of the email, last year saw a significant shift toward placing them within attachments – most likely in an attempt to bypass email security filters.

Upon scanning the QR code within the attachment, the victim was redirected to a phishing page meticulously designed to mimic a Microsoft authentication form.

In addition to fraudulent HR notifications, threat actors created scheduled meetings within the victim’s email calendar, placing DOC or PDF files containing QR codes in the event descriptions. Leveraging calendar invites to distribute malicious links is a legacy technique that was widely observed during scam campaigns in 2019. After several years of relative dormancy, we saw a resurgence of this technique last year, now integrated into more sophisticated spear phishing operations.

In one specific example, the attachment was presented as a “new voicemail” notification. To listen to the recording, the user was prompted to scan a QR code and sign in to their account on the resulting page.

As in the previous scenario, scanning the code redirected the user to a phishing page, where they risked losing access to their Microsoft account or internal corporate sites.

Link protection services

Threat actors utilized more than just QR codes to hide phishing URLs and bypass security checks. In 2025, we discovered that fraudsters began weaponizing link protection services for the same purpose. The primary function of these services is to intercept and scan URLs at the moment of clicking to prevent users from reaching phishing sites or downloading malware. However, attackers are now abusing this technology by generating phishing links that security systems mistakenly categorize as “safe”.

This technique is employed in both mass and spear phishing campaigns. It is particularly dangerous in targeted attacks, which often incorporate employees’ personal data and mimic official corporate branding. When combined with these characteristics, a URL generated through a legitimate link protection service can significantly bolster the perceived authenticity of a phishing email.

After opening a URL that seemed safe, the user was directed to a phishing site.

BEC and fabricated email chains

In Business Email Compromise (BEC) attacks, threat actors have also begun employing new techniques, the most notable of which is the use of fake forwarded messages.

This BEC attack unfolded as follows. An employee would receive an email containing a previous conversation between the sender and another colleague. The final message in this thread was typically an automated out-of-office reply or a request to hand off a specific task to a new assignee. In reality, however, the entire initial conversation with the colleague was completely fabricated. These messages lacked the thread-index headers, as well as other critical header values, that would typically verify the authenticity of an actual email chain.

In the example at hand, the victim was pressured to urgently pay for a license using the provided banking details. The PDF attachments included wire transfer instructions and a counterfeit cover letter from the bank.

The bank does not actually have an office at the address provided in the documents.

Statistics: phishing

In 2025, Kaspersky solutions blocked 554,002,207 attempts to follow fraudulent links. In contrast to the trends of previous years, we did not observe any major spikes in phishing activity; instead, the volume of attacks remained relatively stable throughout the year, with the exception of a minor decline in December.

Anti-Phishing triggers, 2025 (download)

The phishing and scam landscape underwent a shift. While in 2024, we saw a high volume of mass attacks, their frequency declined in 2025. Furthermore, redirection-based schemes, which were frequently used for online fraud in 2024, became less prevalent in 2025.

Map of phishing attacks

As in the previous year, Peru remains the country with the highest percentage (17.46%) of users targeted by phishing attacks. Bangladesh (16.98%) took second place, entering the TOP 10 for the first time, while Malawi (16.65%), which was absent from the 2024 rankings, was third. Following these are Tunisia (16.19%), Colombia (15.67%), the latter also being a newcomer to the TOP 10, Brazil (15.48%), and Ecuador (15.27%). They are followed closely by Madagascar and Kenya, both with a 15.23% share of attacked users. Rounding out the list is Vietnam, which previously held the third spot, with a share of 15.05%.

Country/territory	Share of attacked users**

Top-level domains

In 2025, breaking a trend that had persisted for several years, the majority of phishing pages were hosted within the XYZ TLD zone, accounting for 21.64% – a three-fold increase compared to 2024. The second most popular zone was TOP (15.45%), followed by BUZZ (13.58%). This high demand can be attributed to the low cost of domain registration in these zones. The COM domain, which had previously held the top spot consistently, fell to fourth place (10.52%). It is important to note that this decline is partially driven by the popularity of typosquatting attacks: threat actors frequently spoof sites within the COM domain by using alternative suffixes, such as example-com.site instead of example.com. Following COM is the BOND TLD, entering the TOP 10 for the first time with a 5.56% share. As this zone is typically associated with financial websites, the surge in malicious interest there is a logical progression for financial phishing. The sixth and seventh positions are held by ONLINE (3.39%) and SITE (2.02%), which occupied the fourth and fifth spots, respectively, in 2024. In addition, three domain zones that had not previously appeared in our statistics emerged as popular hosting environments for phishing sites. These included the CFD domain (1.97%), typically used for websites in the clothing, fashion, and design sectors; the Polish national top-level domain, PL (1.75%); and the LOL domain (1.60%).

Organizations targeted by phishing attacks

The rankings of organizations targeted by phishers are based on detections by the Anti-Phishing deterministic component on user computers. The component detects all pages with phishing content that the user has tried to open by following a link in an email message or on the web, as long as links to these pages are present in the Kaspersky database.

Phishing pages impersonating web services (27.42%) and global internet portals (15.89%) maintained their positions in the TOP 10, continuing to rank first and second, respectively. Online stores (11.27%), a traditional favorite among threat actors, returned to the third spot. In 2025, phishers showed increased interest in online gamers: websites mimicking gaming platforms jumped from ninth to fifth place (7.58%). These are followed by banks (6.06%), payment systems (5.93%), messengers (5.70%), and delivery services (5.06%). Phishing attacks also targeted social media (4.42%) and government services (1.77%) accounts.

Statistics: spam

Share of spam in email traffic

In 2025, the average share of spam in global email traffic was 44.99%, representing a decrease of 2.28 percentage points compared to the previous year. Notably, contrary to the trends of the past several years, the fourth quarter was the busiest one: an average of 49.26% of emails were categorized as spam, with peak activity occurring in November (52.87%) and December (51.80%). Throughout the rest of the year, the distribution of junk mail remained relatively stable without significant spikes, maintaining an average share of approximately 43.50%.

In the Russian web segment (Runet), we observed a more substantial decline: the average share of spam decreased by 5.3 percentage points to 43.27%. Deviating from the global trend, the fourth quarter was the quietest period in Russia, with a share of 41.28%. We recorded the lowest level of spam activity in December, when only 36.49% of emails were identified as junk. January and February were also relatively calm, with average values of 41.94% and 43.09%, respectively. Conversely, the Runet figures for March–October correlated with global figures: no major surges were observed, spam accounting for an average of 44.30% of total email traffic during these months.

Countries and territories where spam originated

The top three countries in the 2025 rankings for the volume of outgoing spam mirror the distribution of the previous year: Russia, China, and the United States. However, the share of spam originating from Russia decreased from 36.18% to 32.50%, while the shares of China (19.10%) and the U.S. (10.57%) each increased by approximately 2 percentage points. Germany rose to fourth place (3.46%), up from sixth last year, displacing Kazakhstan (2.89%). Hong Kong followed in sixth place (2.11%). The Netherlands and Japan shared the next spot with identical shares of 1.95%; however, we observed a year-over-year increase in outgoing spam from the Netherlands, whereas Japan saw a decline. The TOP 10 is rounded out by Brazil (1.94%) and Belarus (1.74%), the latter ranking for the first time.

Malicious email attachments

In 2025, Kaspersky solutions blocked 144,722,674 malicious email attachments, an increase of nineteen million compared to the previous year. The beginning and end of the year were traditionally the most stable periods; however, we also observed a notable decline in activity during August and September. Peaks in email antivirus detections occurred in June, July, and November.

Email antivirus detections, 2025 (download)

The most prevalent malicious email attachment in 2025 was the Makoob Trojan family, which covertly harvests system information and user credentials. Makoob first entered the TOP 10 in 2023 in eighth place, rose to third in 2024, and secured the top spot in 2025 with a share of 4.88%. Following Makoob, as in the previous year, was the Badun Trojan family (4.13%), which typically disguises itself as electronic documents. The third spot is held by the Taskun family (3.68%), which creates malicious scheduled tasks, followed by Agensla stealers (3.16%), which were the most common malicious attachments in 2024. Next are Trojan.Win32.AutoItScript scripts (2.88%), appearing in the rankings for the first time.

Conclusion

2026 will undoubtedly be marked by novel methods of exploiting artificial intelligence capabilities. At the same time, messaging app credentials will remain a highly sought-after prize for threat actors. While new schemes are certain to emerge, they will likely supplement rather than replace time-tested tricks and tactics. This underscores the reality that, alongside the deployment of robust security software, users must remain vigilant and exercise extreme caution toward any online offers that raise even the slightest suspicion.

The intensified focus on government service credentials signals a rise in potential impact; unauthorized access to these services can lead to financial theft, data breaches, and full-scale identity theft. Furthermore, the increased abuse of legitimate tools and the rise of multi-stage attacks – which often begin with seemingly harmless files or links – demonstrate a concerted effort by fraudsters to lull users into a false sense of security while pursuing their malicious objectives.
