Apple fixes iOS bug that kept deleted notifications, including chat previews

Apple has released a software update that deals with an issue that could allow deleted notifications to be retrieved. Something that, in at least one reported case, was used by law enforcement during forensic analysis.

Apple fixed the issue in iOS and iPadOS versions 18.7.8 and 26.4.2 (check availability for your device at those links). The update deals with a singular security vulnerability, tracked as CVE-2026-28950.

Although the description is brief—“a logging issue was addressed with improved data redaction”—the impact points us in the right direction.

“Notifications marked for deletion could be unexpectedly retained on the device.”

This suggests that Apple’s bug was that iOS kept copies of notification content in an internal database for longer than intended, even after the messages “disappeared” or the app was uninstalled. In a case reported by 404 Media, law enforcement was able to recover those notifications using standard forensic tools once they had access to the unlocked device. The example in that reported case involved Signal.


Mobile protection, anywhere, anytime.


A response on X by Signal states:

“The FBI was able to forensically extract copies of incoming Signal messages from a defendant’s iPhone, even after the app was deleted, because copies of the content were saved in the device’s push notification database.”

Before we go into the update process, you may want to know that you can mute or hide notifications in Signal, which also protects them from prying eyes. In Signal, open your Settings and tap on Notifications. You can adjust several settings there. For example, I have mine set so I only see the name of the sender.

Install the update

For iOS and iPadOS users, you can check if you’re using the latest software version by going to Settings > General > Software Update. It’s also worth turning on Automatic Updates if you haven’t already. You can do that on the same screen.

Roblox clamps down on chats and age checks as legal pressure builds

Roblox has long faced criticism over child safety on its platform. Now it has started settling with state attorneys over the issue, and the total is climbing fast.

On April 21, Alabama Attorney General Steve Marshall announced a $12.2 million settlement with the child-focused online gaming platform. The State of West Virginia also settled for $11 million the same day. Those came a week after Nevada Attorney General Aaron Ford got the company to hand over $12 million.

Their problem with Roblox is clear from the settlement documents: they believe it hasn’t been adequately protecting children from predators on its platform.

What Roblox has to change

As part of Alabama’s settlement, Roblox must now run age checks on everyone via facial age estimation or a government ID starting May 1. That applies to both new and existing accounts. The company must now also monitor account behavior to catch users who lied about their age.

Adults and under-16s won’t be able to talk with each other at all unless they’re on a “trusted friend” list, added via QR code or a phone-contact import, and users that don’t undergo age verification can’t chat to anyone. 

Communication involving any minor cannot be encrypted, so law enforcement can read it during investigations. West Virginia’s settlement also insists that Roblox alert minors the first time they enter a private chat, so children understand how to communicate safely.

Roblox already stopped people from chatting without age verification as of January this year, but under new measures it will start restricting access to games for those that don’t undergo the process. Starting in June, the platform will split into three tiers: Roblox Kids for ages 5–8 will forbid any chats at all, and will only allow access to games labeled ‘minimal’ or ‘mild’ on its maturity scale. Those who don’t complete age verification will also have these restrictions. The other two account levels are Roblox Select for 9–15 year-olds, and standard accounts for those 16 and up.

Plenty more lawsuits to come

Three settlements in eight days totaling more than $35 million must hurt, but it’s just the beginning. Texas, Florida, Louisiana, Iowa, Nebraska, Kentucky, and Tennessee are all pursuing similar claims: that Roblox exposed children to risk and then misled parents about its safeguards.

In February, LA County sued Roblox, accusing the platform of choosing profit over safety and leaving kids exposed to grooming and explicit content.

Roblox is also separately dealing with nearly 80 federal lawsuits filed by families in California alone. And Australia’s eSafety Commissioner has also issued legally-enforceable transparency notices to Roblox and other tech companies. These force them to detail what they’re doing to protect children. Those notices are backed by fines of A$825,000 a day (that’s about US$590,783) for non-compliance.

Where the money will go

The $12.2 million from Alabama’s settlement funds school resource officers through the state’s Safe School Initiative. Nevada’s is earmarked for the Boys & Girls Club and “nondigital activities,” plus a law-enforcement liaison and an online-safety awareness campaign. West Virginia will invest $500,000 in safety education workshops for parents and children, create a $1.5 million three-year public safety campaign, and spend $2.4 million on a dedicated internet safety specialist for six years.

Stay alert

There’s a predictable rhythm to how big tech companies face down state attorneys general. First comes pushback, then rhetoric about shared values, and then they start handing over cash.

It is a step forward that Roblox is agreeing to new safeguards, but questions remain.

In its own lawsuit against Roblox launched last month, Nebraska complained that the company’s existing age-check technology was inadequate. From the complaint:

“Rather than meaningfully protecting children, the system has repeatedly misclassified users’ ages, placing adults in child chat groups and minors in adult categories, while age-verified accounts for young children have already been traded on third-party marketplaces, undermining any purported safety benefits.”

What happens when the age-estimation AI guesses wrong on a 14-year-old who looks 17, or when a “trusted friend” QR code gets passed around a group chat somewhere it shouldn’t?

The company’s Persona age-check tool has also turned out to do more than check ages: researchers say they found an exposed frontend showing the system was also running facial recognition against watchlists.

Settlements address past concerns, but they don’t guarantee future safety. Parents must still do the work to ensure that they know what their kids are signing up for and who else they might be playing with.

Researcher claims Claude Desktop installs “spyware” on macOS

Security researcher Alexander Hanff wrote an article titled Anthropic secretly installs spyware when you install Claude Desktop.

Claims like that are bound to create two sides, so we searched for an official rebuttal by Anthropic. But we couldn’t find one. It would surprise me very much if they’d be unaware of the claim, since there’s been some noise about it.

Users on Mastodon, Reddit, and LinkedIn are confirming the researcher’s findings and discussing the subject, so it’s hard to imagine Anthropic missed it.

Let’s look at the claims first.

While looking into another matter, the researcher discovered a Native Messaging host manifest on his Mac that he did not knowingly install. On Chrome and other Chromium-based browsers, extensions can exchange messages with native applications if they register a native messaging host that can communicate with the extension. 

By testing on a clean machine, Hanff discovered that Installing Claude Desktop for macOS drops a Native Messaging host manifest into multiple Chromium profiles (Chrome, Edge, Brave, Arc, Vivaldi, Opera, Chromium), even including for browsers that are not actually installed yet.

The Native Messaging host manifest tells a Chromium‑based browser which local executable to invoke when an extension calls a native host, and those hosts run outside the browser sandbox with current users  permissions. Hanff therefore describes this as a “backdoor.” The manifest pre‑authorizes three Chrome extension IDs, so any extension with those IDs can call the helper via connectNative, giving it access to browser automation features.

Another objection is that Claude makes simple deletion futile since the manifest will be recreated the next time the user launches Claude Desktop.

It’s important here to point out that his article is about Claude Desktop, the Electron-based macOS application with bundle identifier com.anthropic.claudefordesktop, distributed as Claude.app. It is not about Claude Code, Anthropic’s command line developer tool. Claude Code is autonomous (“agentic”), allowing you to hand over a task, and it handles the planning and execution until done. So, for Claude Code, it would absolutely make sense to enable communication with browsers, provided they are present on the target system.

So, we have an application that writes into other apps’ profile/support directories (the browsers’ configuration area) and can act as the user, with capabilities like using the logged‑in browser session, DOM inspection, data extraction, form filling, and session recording. This expands the attack surface of every machine this manifest is dropped on, without asking for consent. 

Anthropic’s own launch blog on “Claude for Chrome,” which discusses Anthropic’s internal red‑team experiments, explicitly mentions prompt injection as a key risk and reports attack success rates of 23.6% (no mitigations) and 11.2% (with mitigations). Hanff cites this to argue that a pre‑positioned bridge is a non‑trivial risk.

How bad is it?

Native Messaging is a standard Chromium mechanism. Nothing here is an unknown or exotic technique per se. Chrome’s own documentation explains that Native Messaging hosts run at user privilege and are invoked by browser extensions through a manifest file. And as the researcher pointed out, the bridge does nothing. But it could potentially be abused.

I don’t think it’s fair to say that Claude Desktop installs spyware, but it does open a system up by expanding the attack surface.

Anthropic already had a separate, documented Native Messaging manifest for Claude Code that users sometimes manually copied into other Chromium browsers; the new behavior is that Claude Desktop now drops a Claude‑Desktop‑related manifest into multiple browser paths automatically.

It requires a combination of extension and host. Only combined with a matching browser extension, this bridge enables the user-like capabilities we listed earlier.

What we don’t know yet

Anthropic hasn’t published a detailed technical privacy spec for the Claude Desktop–browser bridge, so we don’t know exactly what data flows when the Chrome integration is used, beyond the general capabilities described in their documentation (session access, DOM reading, etc.).

The detailed analysis and most replication so far are on macOS. We’re in the dark about behavior on Windows and Linux, and the same is true across different browser install paths. That behavior has also not been comprehensively documented in public write‑ups.

I did reach out to Anthropic asking for a response. If and when we get an official response from Anthropic, I’ll add it here, so stay tuned.

Conclusion

Anthropic likely wanted “Claude in Chrome”‑style capabilities across Chromium‑based browsers, but that doesn’t excuse doing it silently and preinstalling the manifest into profile directories for multiple browsers, including ones that are not yet installed.

There are better ways to implement changes like these, and users should at least be made aware of them so they can weigh the advantages against the potential risks.

‘Scattered Spider’ Member ‘Tylerb’ Pleads Guilty

A 24-year-old British national and senior member of the cybercrime group “Scattered Spider” has pleaded guilty to wire fraud conspiracy and aggravated identity theft. Tyler Robert Buchanan admitted his role in a series of text-message phishing attacks in the summer of 2022 that allowed the group to hack into at least a dozen major technology companies and steal tens of millions of dollars worth of cryptocurrency from investors.

Buchanan’s hacker handle “Tylerb” once graced a leaderboard in the English-language criminal hacking scene that tracked the most accomplished cyber thieves. Now in U.S. custody and awaiting sentencing, the Dundee, Scotland native is facing the possibility of more than 20 years in prison.

A screenshot of two photos of Buchanan that appeared in a Daily Mail story dated May 3, 2025.

Two photos published in a Daily Mail story dated May 3, 2025 show Buchanan as a child (left) and as an adult being detained by airport authorities in Spain. “M&S” in this screenshot refers to Marks & Spencer, a major U.K. retail chain that suffered a ransomware attack last year at the hands of Scattered Spider.

Scattered Spider is the name given to a prolific English-speaking cybercrime group known for using social engineering tactics to break into companies and steal data for ransom, often impersonating employees or contractors to deceive IT help desks into granting access.

As part of his guilty plea, Buchanan admitted conspiring with other Scattered Spider members to launch tens of thousands of SMS-based phishing attacks in 2022 that led to intrusions at a number of technology companies, including Twilio, LastPass, DoorDash, and Mailchimp.

The group then used data stolen in those breaches to carry out SIM-swapping attacks that siphoned funds from individual cryptocurrency investors. In an unauthorized SIM-swap, crooks transfer the target’s phone number to a device they control and intercept any text messages or phone calls to the victim’s device — such as one-time passcodes for authentication and password reset links sent via SMS. The U.S. Justice Department said Buchanan admitted to stealing at least $8 million in virtual currency from individual victims throughout the United States.

FBI investigators tied Buchanan to the 2022 SMS phishing attacks after discovering the same username and email address was used to register numerous phishing domains seen in the campaign. The domain registrar NameCheap found that less than a month before the phishing spree, the account that registered those domains logged in from an Internet address in the U.K. FBI investigators said the Scottish police told them the address was leased to Buchanan throughout 2022.

As first reported by KrebsOnSecurity, Buchanan fled the United Kingdom in February 2023, after a rival cybercrime gang hired thugs to invade his home, assault his mother, and threaten to burn him with a blowtorch unless he gave up the keys to his cryptocurrency wallet. That same year, U.K. investigators found a device at Buchanan’s Scotland residence that included data stolen from SMS phishing victims and seed phrases from cryptocurrency theft victims.

Buchanan was arrested by Spanish authorities in June 2024 while trying to board a flight to Italy. He was extradited to the United States and has remained in U.S. federal custody since April 2025.

Buchanan is the second known Scattered Spider member to plead guilty. Noah Michael Urban, 21, of Palm Coast, Fla., was sentenced to 10 years in federal prison last year and ordered to pay $13 million in restitution. Three other alleged co-conspirators — Ahmed Hossam Eldin Elbadawy, 24, a.k.a. “AD,” of College Station, Texas; Evans Onyeaka Osiebo, 21, of Dallas, Texas; and Joel Martin Evans, 26, a.k.a. “joeleoli,” of Jacksonville, North Carolina – still face criminal charges.

Two other alleged Scattered Spider members will soon be tried in the United Kingdom. Owen Flowers, 18, and Thalha Jubair, 20, are facing charges related to the hacking and extortion of several large U.K. retailers, the London transit system, and healthcare providers in the United States. Both have pleaded not guilty, and their trial is slated to begin in June.

Investigators say the Scattered Spider suspects are part of a sprawling cybercriminal community online known as “The Com,” wherein hackers from different cliques boast publicly on Telegram and Discord about high-profile cyber thefts that almost invariably begin with social engineering — tricking people over the phone, email or SMS into giving away credentials that allow remote access to corporate internal networks.

One of the more popular SIM-swapping channels on Telegram has long maintained a leaderboard of the most rapacious SIM-swappers, indexed by their supposed conquests in stealing cryptocurrency. That leaderboard previously listed Buchanan’s hacker alias Tylerb at #65 (out of 100 hackers), with Urban’s moniker “Sosa” coming in at #24.

Buchanan’s sentencing hearing is scheduled for August 21, 2026. According to the Justice Department, he faces a statutory maximum sentence of 22 years in federal prison. However, any sentence the judge hands down in this case may be significantly tempered by a number of mitigating factors in the U.S. Sentencing Guidelines, including the defendant’s age, criminal history, time already served in U.S. custody, and the degree to which they cooperated with federal authorities.

Real Apple notifications are being used to drive tech support scams

Scammers have found a way to abuse legitimate Apple account notification emails to trick targets into calling fake tech support numbers.

According to a report from BleepingComputer, scammers create an Apple account and insert a phishing message into the personal information fields, then modify the account so that Apple sends a genuine security alert about the change to the target.

BleepingComputer was able to replicate the attack.

The attacker creates an Apple ID they control, then stuffs the phishing message into the personal information fields (first name, last name, possibly address), splitting it across fields because they will not fit into just one.

To launch the phish, the attacker changes something benign on their specially created Apple account, such as shipping information, which causes Apple’s systems to send a “Your Apple account was updated” security email.

While the original alert is addressed to the attacker’s iCloud email, they are then able to redistribute it to a wider victim list, for example through a mailing list.

In the copy the targets receive, the email headers still show a legitimate Apple sender, and the presence of the attacker’s iCloud address can even make it look like “someone else” has gained access to the account.

Reconstruction. Image courtesy of BleepingComputer

Because Apple includes those user-supplied fields in the security email, the phishing text is delivered inside a legitimate message sent from Apple’s own infrastructure.

This method, called call-back phishing, filters out suspicious users, so the scammers can focus on the people who fell for the first part.

The emails come from a legitimate source, sail through every security filter because of that, and look convincing enough to scare the receiver into thinking someone spent $899 from their PayPal account.

Phishing email screenshot, courtesy of BleepingComputer

But the structure of the email does not make sense.

“Dear User” is immediately followed by the scam message where your name should have been. The header says it’s about account information rather than a purchase. And the iCloud account does not belong to the recipient. So, once you know how it’s done, they’re not impossible to spot. Which is why we wrote this blog.

And when in doubt, you can always ask Malwarebytes Scam Guard.


Scam or legit? Scam Guard knows.


Is this a scam?
Asking Scam Guard

Scam Guard identified the screenshot as a scam and guides users through the next steps.

Scams like these work, because many users still view phone calls as more trustworthy than email, especially if the email itself passed all the usual technical authenticity checks and they initiated the call themselves.

How to stay safe

Tech support scammers will try to convince callers to install some kind of remote desktop application to steal data from your computer, or ask for financial details so they can steal your money.

To stay safe from these scammers:

  • Be wary of unexpected alerts about high‑value purchases you do not recognize. They are suspicious even if they come from a real domain.
  • Never call a number sent to you by unsolicited means or even found in sponsored search results.
  • Carefully read emails and text messages, even if they come form trustworthy addresses. Does the email make sense from a structural and linguistic point of view?
  • If someone claiming to be support for a legitimate company asks for remote access or payment details during a call, hang up and contact the company through official channels.
  • Use Malwarebytes Scam Guard to analyze any kind of message that alarms you or urges you to take immediate action.

Android 17 ends all-or-nothing access to your contacts

Some of the apps on your phone want your contacts. Most don’t need them all, but have been happily slurping up the lot for years. Google has decided to do something about that with the next version of Android.

Android 17 (currently in preview) is introducing a new Contact Picker that lets users grant apps access to specific contacts rather than the entire list.

Previously, any app that needed a single phone number had to request READ_CONTACTS. That’s a permission that handed over every name, email, and number. It’s the digital equivalent of handing someone your entire Rolodex because they asked for one business card.

An app that can harvest your entire contact list can map your social network, identify your family members, and potentially hand that data to whoever’s buying. So whenever you click “yes” to “show us all your contacts” it isn’t just your privacy you’re playing with.

From Android 17 onward, apps will need to be more specific about what contact data they access. Phone number? Fine. Email address? Sure. Your cousin’s mailing address? Not unless the app has a reason.

Google’s updated Play policy will require apps to use the Contact Picker or the Android Sharesheet as the main way to access contacts. READ_CONTACTS will be reserved for apps that genuinely can’t function without it. 

Location sharing gets the privacy treatment

Location permissions are also set to become more granular and privacy-friendly in Android 17.

Previously, apps could ask for your precise or general location, and you could allow it just once, any time you’re using the app, or not at all. The new button adds nuance by letting app developers ask for your location in the moment, tied to a specific action, like finding a local cafe.

There will also be a persistent indicator to let you know when an app is using your location, similar to the alerts for camera or microphone access. And you’ll be able to find out which apps are tracking you as well.

Google blocked 8.3 billion bad ads in 2025

The tighter permissions management in Android 17 is a big deal for privacy advocates, because overly broad access is how data brokers build detailed profiles about you.

Those profiles can then be used for aggressive or invasive advertising, including scams.


Mobile protection, anywhere, anytime.


Google timed these privacy announcements alongside its latest Ad Safety report, which says it blocked 8.3 billion policy-violating ads and suspended 24.9 million advertiser accounts in the last year. 

The 8.3 billion figure is up from 2024, when Google blocked 5.1 billion ads. The increase suggests that the problem is getting worse, or that Google is getting better at catching it. Scam ads are a big part of that. In 2024, Google blocked 415 million scam-related ads. In 2025, that number grew to 602 million. 

Lest we forget

We’ll give Google credit for trying to tackle this problem from both ends—limiting data collection and cracking down on the kinds of ads that use that data maliciously. But there’s still a sense that it’s not doing quite enough.

Yes, the Android 17 permission changes are good for users, but granular contact access should have been the default years ago. Apple has been doing it for 18 months in iOS 18, and even that was years too late, in our opinion.

And while Google says it caught over 99% of violations before users ever saw them, 1% of an insanely large number is still insanely large.

The ads that still get through are damaging. In December, we reported on sponsored search results pointing to malicious AI chats that instructed people to install infostealer malware. Why does Google run ads that look like search results? Because its business model is driven by advertising revenue. At least it’s making it easier to hide them now.

So we’ll give a cautious hand clap to Google. It’s moving in the right direction. But stories about how it knowingly giving kids’ data inappropriately to advertisers or misusing health data still give us pause.

Mythos: An AI tool too powerful for public release

Anthropic’s most capable model to date, Claude Mythos Preview  (aka Mythos), has been described as a “step change” in AI performance, especially on cybersecurity tasks.

Anthropic tried to keep Mythos a secret until a few weeks ago, when a data leak revealed the existence of what the company said was its most powerful artificial intelligence to date. The models is seen as both a powerful defensive tool, and, potentially, a serious offensive cyberweapon.

For that reason, the company is sharply limiting access and signaling it does not plan to release it broadly to the market right now. Its reported ability to autonomously find and even chain software vulnerabilities at scale sit at the core of both the hype and the danger.

Imagine a tool that can independently find new vulnerabilities in software, systems, and platforms, then turn them into exploits, even if that requires chaining them with other vulnerabilities.

In the wrong hands, that could be a major threat to our cyber safety. So Anthropic has limited access to a small number of organizations worldwide, including major tech firms and a select group of government or security bodies. The NSA is reportedly already using Mythos Preview, apparently to stress‑test and harden sensitive systems, despite the Pentagon labelling Anthropic as a supply chain risk.

Mythos can discover vulnerabilities across large codebases more quickly and reliably than existing tools, and can look for multiple flaws in one system and combine them into multi‑step exploit chains to complete a compromise (for example, going from a simple web bug to a full domain takeover). It would take a bug bounty hunter months to find another vulnerability, let alone one chainable with the one(s) already discovered. Accomplishing that before the first one would be highly unlikely.

In practical terms, that could mean faster attacks, more complex breaches, and less time for companies to fix weaknesses before they’re exploited.

Anthropic itself has highlighted that Mythos can work with minimal supervision for extended periods, meaning it could run systematic attack campaigns at a scale no human team could accomplish.

Anthropic flagged these security risks in an internal document:

  • AI lowers the skill floor for offensive operations. Less-skilled actors could get access to very effective tools, significantly increasing the number of advanced attacks.
  • Techniques like fuzzing, dictionary attacks, and other brute force methods become much more effective when sped up by automation. AI-assisted iteration can provide an attacker with a lot more tries before an attack gets noticed.

But the most concerning conclusion was that the offensive side is iterating faster in the current phase of AI development, and security teams are generally later adopters of AI tooling than their adversaries.

As we know, AI in cybersecurity works both ways. It helps us defend against new threats, but it can also be used to create them. Which is why, in the wrong hands, Mythos can turn out to be a formidable adversary.

The goal stays the same, but the way to get there is paved by tools like Mythos. From the attacker’s seat, nothing about the destination is new. The novelty is that Mythos now automates the map, the vehicle, and most of the driving.

This old-school scam is still working

When we read about this new malware tactic, or that novel social engineering approach, it’s easy to forget that there are scammers out there making a living from ancient methods.

Recently, one of our researchers received this variation on the good old Nigerian advance-fee scam.

screenshot of email

From: Mrs.Inga-Britt Ahlenius.
Internal Audit, Monitoring, Consulting and Investigations Division
UNITED NATIONS SCAM VICTIMS COMPENSATIONS PAYMENTS.

Attn; Dear Scam victim/Beneficiary;

United Nations have Approved to pay 150 scam victims $5,000,000.00 (FIVE MILLION UNITED STATE DOLLAR) each.

You are listed as one of the scammed victims to be paid this amount, get back to me as soon as possible for the immediate payments of your $5,000,000.00 compensation funds.

You can contact the paying bank United Bank For Africa (UBA) on the below information

Name: Dr. Kingsley Obiora
Email: kingsleyobiora@gmail.com
Whatsapp Number, +234 913 998 1014 Sincerely yours,
Mrs.Inga-Britt Ahlenius


Scam or legit? Scam Guard knows.


The scammers got a few details right. Anyone looking up the names in the email will find that they exist and are associated with the mentioned organizations.

IngaBritt Monica Stigsdotter Ahlenius is a Swedish auditor, public servant and former Under-Secretary-General for the United Nations.

The name “Inga‑Britt Ahlenius” has been reused across many such 419‑style advance‑fee scams, sometimes claiming she is a UN fund monitoring agent or under‑secretary general distributing tens of millions in “compensation” or “unclaimed funds.”

Kingsley Obiora is a Nigerian economist who served as the Deputy Governor of Economic Policy at the Central Bank of Nigeria from 2020 to 2023. Which lends a degree of credibility to the Nigerian country code (+234) in the number they want us to contact by WhatsApp.

So, we decided to put our “friend” Tess to work once again. Loyal readers will remember how Tess almost fell for a task scammer. So maybe she’s eligible for that five-million-dollar compensation.

Promising a $5M ATM card

They came right to the point. We’d have to pay a courier fee to get our $5 million dollar ATM card. And I’m pretty sure that if we agreed to pay that, additional costs would swiftly follow. Once you’ve invested a bit of money, you’re likely to keep going since you don’t want to lose what you’ve already paid.

So, I offered to pick up the ATM card in person. Always wanted to see Nigeria.

Offering my fake company ID card worked

For a while I thought they saw through my bluff. Maybe I shouldn’t have disclosed just yet that I work for Malwarebytes. But it quickly became clear they trusted me about as much as I trusted them.

Visiting address

I’ll play along as long as I can, but after giving me the physical address of the UBA bank in Lagos, Nigeria, they started to make it more difficult to pick up the ATM card in person.

Cancelled in a week

A week is not a long time to arrange a trip to Nigeria, so I tried to get an idea of how much the “courier” would set me back before they gave up on me.

$875 for the courier

I didn’t expect it to be that much, to be honest. Maybe they thought they could raise the price since I contemplated to pick it up in person. Or they just wanted to get rid of me. You’d expect them to charge maybe €75 for the courier and then come up with €200 for stamp duty and €600 for insurance later on.

Consequences are real

It’s easy to laugh at talk of five‑million‑dollar ATM cards, but campaigns like this still make money. Behind every “Dear Scam victim/Beneficiary” is someone who is lonely, in debt, or simply overwhelmed by official‑sounding language. Once they’ve paid the first “courier fee,” the sunk‑cost effect kicks in, and it becomes harder and harder to walk away.

This is especially true for people who have already been victims of scams, who are clearly the target here.

How to stay safe

Tess’ efforts have helped us highlight the red flags in this type of scam:

  • Receiving news of a huge payout out of the blue should definitely trigger the “too good to be true” alarm bells.
  • For important communications, free webmail and WhatsApp are rarely the official contact channels.
  • Scammers apply pressure to act quickly and ask you to pay a fee before you receive anything.
  • They often use vague job titles and ask you to keep things quiet.
  • Odd language and capitalization can be a clue, although AI is making these less common.

Any one of these signs is a reason to stop and delete the email. Together, they spell out a classic advance‑fee scam.

For Tess this was a safe experiment: no money lost, just a few evenings spent sparring with a “UN compensation officer” on WhatsApp. For the people these criminals really want to reach, the stakes are much higher.

If you, or someone you care about, ever receives a message promising life‑changing money in exchange for a small courier fee or processing charge, treat it as a warning sign, not a windfall.

Close the tab, delete the message, and, if in doubt, ask a trusted friend or advisor before you act.

The easiest way to recognize a golden‑oldie scam is still the simplest: if it sounds too good to be true, it probably isn’t true.

“Your shipment has arrived” email hides remote access software

An attachment in an email impersonating DHL about a shipment contains a link to a preconfigured SimpleHelp remote access tool—an ideal starting point for attackers to explore a network, steal data, and drop additional malware.

A German industrial spare parts and equipment supplier received an email pretending to be from DHL, claiming a shipment had arrived.

Screenshot of email pretending to be from DHL

Given their line of business, I imagine they get this type of email all the time. But a few details stood out:

  • The sender’s email address did not belong to DHL,
  • the receiver address was the general info@ for the company,
  • the images in the email were hosted on ecp.yusercontent.com,  
  • and, most importantly, there was attachment.

While the remote content is hosted on a legitimate Yahoo webpage commonly used to serve images and other content in Yahoo Mail, this is not something DHL typically uses.

The attachment, a PDF file called AWB-Doc0921.pdf is just a blurred image with a Microsoft-branded button that prompts the victim to “Continue” to access a secure file.

In reality, clicking the button downloads a file called AWB-Doc0921.scr from the domain longhungphatlogistics[.]vn, a domain belonging to a Vietnamese logistics company that was likely compromised to host malware.

A .scr file is a Windows file, which is an executable (.exe) file used to launch screensavers. They are often used to hide malicious code because Windows trusts them, allowing them to bypass some security layers. 

In this case, the file is a modified installer of a remote access tool signed by SimpleHelp.

SimpleHelp is a remote support and remote monitoring and management (RMM) platform. It allows remote desktop control, file transfer, diagnostics, and unattended access. In the wrong hands, that’s effectively a support-style backdoor. Attackers can use it for reconnaissance, credential theft, lateral movement, defense evasion, and staging further malware, including ransomware. We’ve seen SimpleHelp abused in this way before.

This is basically a beaconing model. Once installed, the system connects out to the attacker’s server, which is more likely to be allowed through NAT and firewalls than inbound connections. Because the user initiated the install, the attacker gets immediate visibility of the system and can reconnect later whenever the service is running. In the case of a phish, that means the lure only has to get the victim to execute the file once. After that, the attacker’s console can show the new machine as a manageable asset.

For what seems to be a non-targeted attack, the campaign shows a decent level of sophistication by using legitimate components to trick targets into running the remote access tool.

How to stay safe

The good news: once you know what to look for, these attacks are much easier to spot and block. The bad news: they’re cheap, scalable, and will continue to circulate.

So, the next time a “PDF” prompts you to download a file, pause to think about what might be hiding under the hood.

Beyond avoiding unsolicited attachments, here are a few ways to stay safe:

  • Only access your accounts through official apps or by typing the official website directly into your browser.
  • Check file extensions carefully. Even if a file installs a legitimate tool, it may not be safe to run it.
  • Enable multi-factor authentication for your critical accounts.
  • Use an up-to-date, real-time anti-malware solution with a web protection module.

“iCloud storage is full” scam is back, and now it wants your payment details

A few months ago, we reported on a fake cloud storage alert that triggered a redirect chain to an app that has since been delisted from the Apple Store.

The threat of losing your photos is a powerful lure, so scammers are now using it to steal personal and financial details.

The Guardian warns about an iCloud-themed campaign that start with a few “your iCloud storage is full’ messages, then escalates to threats. If you don’t respond or take action, the emails claim your data will be wiped on a specific date.

US Consumer Affairs has urged users not to click any links and to contact Apple directly if they receive such messages.

The deadline in the emails is never far away, usually just two days. No scammer ever wants you to think things through before you act, so there is always time pressure.

We’ve seen these emails in English and Spanish. Oddly, the monthly rate is set at 99 pence or 99 euro cents respectively.

The 0.99 seems to be the magic number. In reality, scammers don’t care about the payment. What they want is for you fill out the form on their phishing site.

Email saying you must upgrade to iCloud+ or lose your photos
Email saying you must upgrade to iCloud+ or lose your photos

The screenshot above is just one of many examples. There are plenty of variations, but they all follow the same them: make a small payment to stop the files in your iCloud storage from being deleted.

The websites these emails link to also vary, but they all ask for personal and payment details to complete that payment.

How to stay safe

It’s worth remembering that Apple does notify users when their iCloud storage is nearing capacity, but those alerts appear within your device settings or as official system notifications. They don’t come through unsolicited text messages or emails with external links. If you need to check your storage, go directly to Settings on your device and review your iCloud usage.

So, to stay safe:

  • Always access your account through our official website.
  • Never share your password with anyone.
  • Never click on links in unsolicited emails without verifying with a trusted source.
  • Use an up-to-date, real-time anti-malware solution with a web protection component.
  • Do not engage with websites that attract visitors like this.

AI clickbait can turn your notifications into a scam feed

Pushpaganda is the name researchers have given to an AI-assisted ad fraud, social engineering, and scareware operation targeting mobile users.

For most people, Pushpaganda starts as something that looks completely normal. For example, a recommended article in your Google Discover feed (the personalized news stream on your phone) or one of the suggested stories you see when you open a new Chrome tab. The operators behind this campaign use AI‑generated articles and images, plus aggressive SEO or paid placement, to get their content surfaced in those feeds so it feels like any other story about money, tech, or politics.

The topics are classic clickbait. You might see a card about a new tax refund, a government payout, a bank deposit, or some too‑good‑to‑be‑true gadget like a $100 phone with a “300MP camera.” On a small mobile screen, with a matching thumbnail and a headline tailored to your region, that’s exactly the kind of thing many people would reasonably tap.

Having tapped, you land on an attacker-controlled site that looks like a regular article page but wastes no time throwing up a browser prompt asking to send you notifications. Many users have been trained by years of pop-ups to click “Allow” just to get it out of the way, especially if the page claims you need to click “Allow” to continue reading or see the offer.

Some pages will falsely claim you have to click Allow to continue reading
Some pages will falsely claim you have to click Allow to continue reading

Unfortunately, with that single tap, the site now has permission to push messages straight to your Android or desktop, where they sit alongside emails, chats, and real alerts from banks or government apps. Because the notifications don’t behave like traditional pop‑ups and can bypass normal ad‑blocking, many people don’t realize they’ve effectively subscribed to a scam channel.

The result is a stream of alarming notifications that seem to come out of nowhere and have little to do with the original site you visited, so the link between the site and the notifications is usually lost on the victims. Clicking those notifications rarely leads to what they promise. Instead, you’re pushed to another domain in the same network, which may ask for even more permissions, personal data, or try to funnel you into financial scams. Over time, this can expose you to fake investment schemes, fraudulent “tech support” numbers, or pages pushing questionable subscriptions.

All of this costs you time and attention, and sometimes money. At best, you end up with a polluted notification tray full of fake alerts that make it harder to spot something genuinely important. At worst, you follow one scare message too far, hand over personal details or payment information, and become the victim of fraud, identity theft, or aggressive subscription traps. And even if you never click again, your browser is still quietly loading pages and ads you never asked for.

How to stay safe from Pushpaganda

Treat “Allow notifications” prompts as potential traps, especially on sites you’ve never heard of that you reached via a feed or a search result. And even more so if they come with additional, misleading, instructions.

Besides that you should:

  • Be skeptical of sensational cards in your Discover feed that promise sudden cash, miracle devices, or dramatic political revelations.
  • Don’t trust buttons that scream “Apply now,” “Claim now,” or “Join WhatsApp” on pages that already feel pushy or poorly written.
  • Keep your browser, operating system (OS), and other important software up to date.
  • Use a security app that can block malicious websites and scam pages before they load.

Scammers know more about you than you think.

Russia Hacked Routers to Steal Microsoft Office Tokens

Hackers linked to Russia’s military intelligence units are using known flaws in older Internet routers to mass harvest authentication tokens from Microsoft Office users, security experts warned today. The spying campaign allowed state-backed Russian hackers to quietly siphon authentication tokens from users on more than 18,000 networks without deploying any malicious software or code.

Microsoft said in a blog post today it identified more than 200 organizations and 5,000 consumer devices that were caught up in a stealthy but remarkably simple spying network built by a Russia-backed threat actor known as “Forest Blizzard.”

Also known as APT28 and Fancy Bear, Forest Blizzard is attributed to the military intelligence units within Russia’s General Staff Main Intelligence Directorate (GRU). APT 28 famously compromised the Hillary Clinton campaign, the Democratic National Committee, and the Democratic Congressional Campaign Committee in 2016 in an attempt to interfere with the U.S. presidential election.

Researchers at Black Lotus Labs, a security division of the Internet backbone provider Lumen, found that at the peak of its activity in December 2025, Forest Blizzard’s surveillance dragnet ensnared more than 18,000 Internet routers that were mostly unsupported, end-of-life routers, or else far behind on security updates. A new report from Lumen says the hackers primarily targeted government agencies—including ministries of foreign affairs, law enforcement, and third-party email providers.

Black Lotus Security Engineer Ryan English said the GRU hackers did not need to install malware on the targeted routers, which were mainly older Mikrotik and TP-Link devices marketed to the Small Office/Home Office (SOHO) market. Instead, they used known vulnerabilities to modify the Domain Name System (DNS) settings of the routers to include DNS servers controlled by the hackers.

As the U.K.’s National Cyber Security Centre (NCSC) notes in a new advisory detailing how Russian cyber actors have been compromising routers, DNS is what allows individuals to reach websites by typing familiar addresses, instead of associated IP addresses. In a DNS hijacking attack, bad actors interfere with this process to covertly send users to malicious websites designed to steal login details or other sensitive information.

English said the routers attacked by Forest Blizzard were reconfigured to use DNS servers that pointed to a handful of virtual private servers controlled by the attackers. Importantly, the attackers could then propagate their malicious DNS settings to all users on the local network, and from that point forward intercept any OAuth authentication tokens transmitted by those users.

Because those tokens are typically transmitted only after the user has successfully logged in and gone through multi-factor authentication, the attackers could gain direct access to victim accounts without ever having to phish each user’s credentials and/or one-time codes.

“Everyone is looking for some sophisticated malware to drop something on your mobile devices or something,” English said. “These guys didn’t use malware. They did this in an old-school, graybeard way that isn’t really sexy but it gets the job done.”

Microsoft refers to the Forest Blizzard activity as using DNS hijacking “to support post-compromise adversary-in-the-middle (AiTM) attacks on Transport Layer Security (TLS) connections against Microsoft Outlook on the web domains.” The software giant said while targeting SOHO devices isn’t a new tactic, this is the first time Microsoft has seen Forest Blizzard using “DNS hijacking at scale to support AiTM of TLS connections after exploiting edge devices.”

Black Lotus Labs engineer Danny Adamitis said it will be interesting to see how Forest Blizzard reacts to today’s flurry of attention to their espionage operation, noting that the group immediately switched up its tactics in response to a similar NCSC report (PDF) in August 2025. At the time, Forest Blizzard was using malware to control a far more targeted and smaller group of compromised routers. But Adamitis said the day after the NCSC report, the group quickly ditched the malware approach in favor of mass-altering the DNS settings on thousands of vulnerable routers.

“Before the last NCSC report came out they used this capability in very limited instances,” Adamitis told KrebsOnSecurity. “After the report was released they implemented the capability in a more systemic fashion and used it to target everything that was vulnerable.”

TP-Link was among the router makers facing a complete ban in the United States. But on March 23, the U.S. Federal Communications Commission (FCC) took a much broader approach, announcing it would no longer certify consumer-grade Internet routers that are produced outside of the United States.

The FCC warned that foreign-made routers had become an untenable national security threat, and that poorly-secured routers present “a severe cybersecurity risk that could be leveraged to immediately and severely disrupt U.S. critical infrastructure and directly harm U.S. persons.”

Experts have countered that few new consumer-grade routers would be available for purchase under this new FCC policy (besides maybe Musk’s Starlink satellite Internet routers, which are produced in Texas). The FCC says router makers can apply for a special “conditional approval” from the Department of War or Department of Homeland Security, and that the new policy does not affect any previously-purchased consumer-grade routers.

Germany Doxes “UNKN,” Head of RU Ransomware Gangs REvil, GandCrab

An elusive hacker who went by the handle “UNKN” and ran the early Russian ransomware groups GandCrab and REvil now has a name and a face. Authorities in Germany say 31-year-old Russian Daniil Maksimovich Shchukin headed both cybercrime gangs and helped carry out at least 130 acts of computer sabotage and extortion against victims across the country between 2019 and 2021.

Shchukin was named as UNKN (a.k.a. UNKNOWN) in an advisory published by the German Federal Criminal Police (the “Bundeskriminalamt” or BKA for short). The BKA said Shchukin and another Russian — 43-year-old Anatoly Sergeevitsch Kravchuk — extorted nearly $2 million euros across two dozen cyberattacks that caused more than 35 million euros in total economic damage.

Daniil Maksimovich SHCHUKIN, a.k.a. UNKN, and Anatoly Sergeevitsch Karvchuk, alleged leaders of the GandCrab and REvil ransomware groups.

Germany’s BKA said Shchukin acted as the head of one of the largest worldwide operating ransomware groups GandCrab and REvil, which pioneered the practice of double extortion — charging victims once for a key needed to unlock hacked systems, and a separate payment in exchange for a promise not to publish stolen data.

Shchukin’s name appeared in a Feb. 2023 filing (PDF) from the U.S. Justice Department seeking the seizure of various cryptocurrency accounts associated with proceeds from the REvil ransomware gang’s activities. The government said the digital wallet tied to Shchukin contained more than $317,000 in ill-gotten cryptocurrency.

The GandCrab ransomware affiliate program first surfaced in January 2018, and paid enterprising hackers huge shares of the profits just for hacking into user accounts at major corporations. The GandCrab team would then try to expand that access, often siphoning vast amounts of sensitive and internal documents in the process. The malware’s curators shipped five major revisions to the GandCrab code, each corresponding with sneaky new features and bug fixes aimed at thwarting the efforts of computer security firms to stymie the spread of the malware.

On May 31, 2019, the GandCrab team announced the group was shutting down after extorting more than $2 billion from victims. “We are a living proof that you can do evil and get off scot-free,” GandCrab’s farewell address famously quipped. “We have proved that one can make a lifetime of money in one year. We have proved that you can become number one by general admission, not in your own conceit.”

The REvil ransomware affiliate program materialized around the same as GandCrab’s demise, fronted by a user named UNKNOWN who announced on a Russian cybercrime forum that he’d deposited $1 million in the forum’s escrow to show he meant business. By this time, many cybersecurity experts had concluded REvil was little more than a reorganization of GandCrab.

UNKNOWN also gave an interview to Dmitry Smilyanets, a former malicious hacker hired by Recorded Future, wherein UNKNOWN described a rags-to-riches tale unencumbered by ethics and morals.

“As a child, I scrounged through the trash heaps and smoked cigarette butts,” UNKNOWN told Recorded Future. “I walked 10 km one way to the school. I wore the same clothes for six months. In my youth, in a communal apartment, I didn’t eat for two or even three days. Now I am a millionaire.”

As described in The Ransomware Hunting Team by Renee Dudley and Daniel Golden, UNKNOWN and REvil reinvested significant earnings into improving their success and mirroring practices of legitimate businesses. The authors wrote:

“Just as a real-world manufacturer might hire other companies to handle logistics or web design, ransomware developers increasingly outsourced tasks beyond their purview, focusing instead on improving the quality of their ransomware. The higher quality ransomware—which, in many cases, the Hunting Team could not break—resulted in more and higher pay-outs from victims. The monumental payments enabled gangs to reinvest in their enterprises. They hired more specialists, and their success accelerated.”

“Criminals raced to join the booming ransomware economy. Underworld ancillary service providers sprouted or pivoted from other criminal work to meet developers’ demand for customized support. Partnering with gangs like GandCrab, ‘cryptor’ providers ensured ransomware could not be detected by standard anti-malware scanners. ‘Initial access brokerages’ specialized in stealing credentials and finding vulnerabilities in target networks, selling that access to ransomware operators and affiliates. Bitcoin “tumblers” offered discounts to gangs that used them as a preferred vendor for laundering ransom payments. Some contractors were open to working with any gang, while others entered exclusive partnerships.”

REvil would evolve into a feared “big-game-hunting” machine capable of extracting hefty extortion payments from victims, largely going after organizations with more than $100 million in annual revenues and fat new cyber insurance policies that were known to pay out.

Over the July 4, 2021 weekend in the United States, REvil hacked into and extorted Kaseya, a company that handled IT operations for more than 1,500 businesses, nonprofits and government agencies. The FBI would later announce they’d infiltrated the ransomware group’s servers prior to the Kaseya hack but couldn’t tip their hand at the time. REvil never recovered from that core compromise, or from the FBI’s release of a free decryption key for REvil victims who couldn’t or didn’t pay.

Shchukin is from Krasnodar, Russia and is thought to reside there, the BKA said.

“Based on the investigations so far, it is assumed that the wanted person is abroad, presumably in Russia,” the BKA advised. “Travel behaviour cannot be ruled out.”

There is little that connects Shchukin to UNKNOWN’s various accounts on the Russian crime forums. But a review of the Russian crime forums indexed by the cyber intelligence firm Intel 471 shows there is plenty connecting Shchukin to a hacker identity called “Ger0in” who operated large botnets and sold “installs” — allowing other cybercriminals to rapidly deploy malware of their choice to thousands of PCs in one go. However, Ger0in was only active between 2010 and 2011, well before UNKNOWN’s appearance as the REvil front man.

A review of the mugshots released by the BKA at the image comparison site Pimeyes found a match on this birthday celebration from 2023, which features a young man named Daniel wearing the same fancy watch as in the BKA photos.

Update, April 6, 12:06 p.m. ET: A reader forwarded this English-dubbed audio recording from a ccc.de (37C3) conference talk in Germany from 2023 that previously outed Shchukin as the REvil leader (Shchuckin is mentioned at around 24:25).

‘CanisterWorm’ Springs Wiper Attack Targeting Iran

A financially motivated data theft and extortion group is attempting to inject itself into the Iran war, unleashing a worm that spreads through poorly secured cloud services and wipes data on infected systems that use Iran’s time zone or have Farsi set as the default language.

Experts say the wiper campaign against Iran materialized this past weekend and came from a relatively new cybercrime group known as TeamPCP. In December 2025, the group began compromising corporate cloud environments using a self-propagating worm that went after exposed Docker APIs, Kubernetes clusters, Redis servers, and the React2Shell vulnerability. TeamPCP then attempted to move laterally through victim networks, siphoning authentication credentials and extorting victims over Telegram.

In a profile of TeamPCP published in January, the security firm Flare said the group weaponizes exposed control planes rather than exploiting endpoints, predominantly targeting cloud infrastructure over end-user devices, with Azure (61%) and AWS (36%) accounting for 97% of compromised servers.

“TeamPCP’s strength does not come from novel exploits or original malware, but from the large-scale automation and integration of well-known attack techniques,” Flare’s Assaf Morag wrote. “The group industrializes existing vulnerabilities, misconfigurations, and recycled tooling into a cloud-native exploitation platform that turns exposed infrastructure into a self-propagating criminal ecosystem.”

On March 19, TeamPCP executed a supply chain attack against the vulnerability scanner Trivy from Aqua Security, injecting credential-stealing malware into official releases on GitHub actions. Aqua Security said it has since removed the harmful files, but the security firm Wiz notes the attackers were able to publish malicious versions that snarfed SSH keys, cloud credentials, Kubernetes tokens and cryptocurrency wallets from users.

Over the weekend, the same technical infrastructure TeamPCP used in the Trivy attack was leveraged to deploy a new malicious payload which executes a wiper attack if the user’s timezone and locale are determined to correspond to Iran, said Charlie Eriksen, a security researcher at Aikido. In a blog post published on Sunday, Eriksen said if the wiper component detects that the victim is in Iran and has access to a Kubernetes cluster, it will destroy data on every node in that cluster.

“If it doesn’t it will just wipe the local machine,” Eriksen told KrebsOnSecurity.

Image: Aikido.dev.

Aikido refers to TeamPCP’s infrastructure as “CanisterWorm” because the group orchestrates their campaigns using an Internet Computer Protocol (ICP) canister — a system of tamperproof, blockchain-based “smart contracts” that combine both code and data. ICP canisters can serve Web content directly to visitors, and their distributed architecture makes them resistant to takedown attempts. These canisters will remain reachable so long as their operators continue to pay virtual currency fees to keep them online.

Eriksen said the people behind TeamPCP are bragging about their exploits in a group on Telegram and claim to have used the worm to steal vast amounts of sensitive data from major companies, including a large multinational pharmaceutical firm.

“When they compromised Aqua a second time, they took a lot of GitHub accounts and started spamming these with junk messages,” Eriksen said. “It was almost like they were just showing off how much access they had. Clearly, they have an entire stash of these credentials, and what we’ve seen so far is probably a small sample of what they have.”

Security experts say the spammed GitHub messages could be a way for TeamPCP to ensure that any code packages tainted with their malware will remain prominent in GitHub searches. In a newsletter published today titled GitHub is Starting to Have a Real Malware Problem, Risky Business reporter Catalin Cimpanu writes that attackers often are seen pushing meaningless commits to their repos or using online services that sell GitHub stars and “likes” to keep malicious packages at the top of the GitHub search page.

This weekend’s outbreak is the second major supply chain attack involving Trivy in as many months. At the end of February, Trivy was hit as part of an automated threat called HackerBot-Claw, which mass exploited misconfigured workflows in GitHub Actions to steal authentication tokens.

Eriksen said it appears TeamPCP used access gained in the first attack on Aqua Security to perpetrate this weekend’s mischief. But he said there is no reliable way to tell whether TeamPCP’s wiper actually succeeded in trashing any data from victim systems, and that the malicious payload was only active for a short time over the weekend.

“They’ve been taking [the malicious code] up and down, rapidly changing it adding new features,” Eriksen said, noting that when the malicious canister wasn’t serving up malware downloads it was pointing visitors to a Rick Roll video on YouTube.

“It’s a little all over the place, and there’s a chance this whole Iran thing is just their way of getting attention,” Eriksen said. “I feel like these people are really playing this Chaotic Evil role here.”

Cimpanu observed that supply chain attacks have increased in frequency of late as threat actors begin to grasp just how efficient they can be, and his post documents an alarming number of these incidents since 2024.

“While security firms appear to be doing a good job spotting this, we’re also gonna need GitHub’s security team to step up,” Cimpanu wrote. “Unfortunately, on a platform designed to copy (fork) a project and create new versions of it (clones), spotting malicious additions to clones of legitimate repos might be quite the engineering problem to fix.”

Update, 2:40 p.m. ET: Wiz is reporting that TeamPCP also pushed credential stealing malware to the KICS vulnerability scanner from Checkmarx, and that the scanner’s GitHub Action was compromised between 12:58 and 16:50 UTC today (March 23rd).

Feds Disrupt IoT Botnets Behind Huge DDoS Attacks

The U.S. Justice Department joined authorities in Canada and Germany in dismantling the online infrastructure behind four highly disruptive botnets that compromised more than three million Internet of Things (IoT) devices, such as routers and web cameras. The feds say the four botnets — named Aisuru, Kimwolf, JackSkid and Mossad — are responsible for a series of recent record-smashing distributed denial-of-service (DDoS) attacks capable of knocking nearly any target offline.

Image: Shutterstock, @Elzicon.

The Justice Department said the Department of Defense Office of Inspector General’s (DoDIG) Defense Criminal Investigative Service (DCIS) executed seizure warrants targeting multiple U.S.-registered domains, virtual servers, and other infrastructure involved in DDoS attacks against Internet addresses owned by the DoD.

The government alleges the unnamed people in control of the four botnets used their crime machines to launch hundreds of thousands of DDoS attacks, often demanding extortion payments from victims. Some victims reported tens of thousands of dollars in losses and remediation expenses.

The oldest of the botnets — Aisuru — issued more than 200,000 attacks commands, while JackSkid hurled at least 90,000 attacks. Kimwolf issued more than 25,000 attack commands, the government said, while Mossad was blamed for roughy 1,000 digital sieges.

The DOJ said the law enforcement action was designed to prevent further infection to victim devices and to limit or eliminate the ability of the botnets to launch future attacks. The case is being investigated by the DCIS with help from the FBI’s field office in Anchorage, Alaska, and the DOJ’s statement credits nearly two dozen technology companies with assisting in the operation.

“By working closely with DCIS and our international law enforcement partners, we collectively identified and disrupted criminal infrastructure used to carry out large-scale DDoS attacks,” said Special Agent in Charge Rebecca Day of the FBI Anchorage Field Office.

Aisuru emerged in late 2024, and by mid-2025 it was launching record-breaking DDoS attacks as it rapidly infected new IoT devices. In October 2025, Aisuru was used to seed Kimwolf, an Aisuru variant which introduced a novel spreading mechanism that allowed the botnet to infect devices hidden behind the protection of the user’s internal network.

On January 2, 2026, the security firm Synthient publicly disclosed the vulnerability Kimwolf was using to propagate so quickly. That disclosure helped curtail Kimwolf’s spread somewhat, but since then several other IoT botnets have emerged that effectively copy Kimwolf’s spreading methods while competing for the same pool of vulnerable devices. According to the DOJ, the JackSkid botnet also sought out systems on internal networks just like Kimwolf.

The DOJ said its disruption of the four botnets coincided with “law enforcement actions” conducted in Canada and Germany targeting individuals who allegedly operated those botnets, although no further details were available on the suspected operators.

In late February, KrebsOnSecurity identified a 22-year-old Canadian man as a core operator of the Kimwolf botnet. Multiple sources familiar with the investigation told KrebsOnSecurity the other prime suspect is a 15-year-old living in Germany.
