Short-form video platforms like TikTok and Instagram Reels have become the latest way cybercriminals spread malware.

We’ve already seen attackers move away from traditional phishing emails and toward tactics that trick people into installing malware themselves. Now they’re being lured with slick social media videos that promise free Spotify Premium, free Windows activation, or free Microsoft Office, but instead leave people with infostealers on their Windows devices.

Researchers at ReversingLabs uncovered two active campaigns that use short videos to trick users into running dangerous PowerShell commands or visiting malicious download sites. Similar campaigns have been reported by other researchers and national cybersecurity agencies, suggesting a growing trend: Cybercriminals are learning how to use social media algorithms just as effectively as marketers.

In true social media fashion, the videos on platforms like TikTok and Instagram Reels claim to solve a problem you didn’t know you had. The catch is that following the instructions delivers malware to your device.

How the scam works

The first campaign looks deceptively professional.

Accounts with names like “windows.tips” or “windows.insights” use Windows-style branding and post polished tutorial videos that resemble genuine tech support content. The videos are tagged with Windows and Office-related keywords so they appear alongside legitimate troubleshooting and tips content.

The videos promise to unlock Spotify Premium, Microsoft Office, or Windows for free. Viewers are then guided through step-by-step instructions that include opening Powershell, a legitimate Windows admin tool, and pasting in commands. Those commands download and run malware, much like the ClickFix scams we’ve covered before.

The malware was identified as Vidar, an infostealer designed to steal sensitive informtion from infected devices. Vidar commonly targets:

• Saved browser passwords
• Autofill data
• Browser cookies
• Cryptocurrency wallets
• Two-factor authentication (2FA) data
• TOR browser data

The stolen information is then sent back to servers controlled by the attackers.

How to stay safe

Research into similar TikTok-based attacks shows these scripts commonly add exclusions to Windows Defender, making it harder for security software to detect future malicious activity.

Fortunately, there are  a few simple ways to protect yourself:  

• Only download software from official vendor websites.  
• Be skeptical of “free”, cracked, or unofficial versions of paid software. 
• Don’t follow instructions on a webpage without thinking them through, especially if the page asks you to run commands on your device or copy and paste code. Many ClickFix pages use countdowns, fake user counters, or other pressure tactics to make you act quickly.
• Check that downloaded files match what you expected to download.
• Verify a file’s publisher and digital signature before you run it. On Windows, you can usually check this by right-clicking the file, selecting Properties > Digital Signatures. Keep in mind that a valid signature does not guarantee a file is safe, but missing or suspicious signatures are often a red flag. 
• Use a real-time, up-to-date anti-malware solution to block malware like infostealers before it runs.

Pro tip: If you’re unsure whether a video, message, or website is legitimate, you can ask Malwarebytes Scam Guard about it. It can help identify suspicious content and advise you on what to do next.

We don’t just report on threats—we help safeguard your entire digital identity

Cybersecurity risks should never spread beyond a headline. Protect your, and your family’s, personal information by using identity protection.

Hacktivist group Anna’s Archive claims to have scraped almost all of Spotify’s catalog and is now seeding it via BitTorrent, effectively turning a streaming platform into a roughly 300 TB pirate “preservation archive.”

On its blog, the group states:

“A while ago, we discovered a way to scrape Spotify at scale. We saw a role for us here to build a music archive primarily aimed at preservation.”

Spotify insists that the hacktivists obtained no user data. Still, the incident highlights how large‑scale scraping, digital rights management (DRM) circumvention, and weak abuse controls can turn major content platforms into high‑value targets.

Anna’s Archive claims it obtained metadata for around 256 million tracks and audio files for roughly 86 million songs, totaling close to 300 TB. Reportedly, this represents about 99.9% of Spotify’s catalog and roughly 99.6% of all streams.

Spotify says it has “identified and disabled the nefarious user accounts that engaged in unlawful scraping” and implemented new safeguards.

From a security perspective, this incident is a textbook example of how scraping can escalate beyond “just metadata” into industrial‑scale content theft. By combining public APIs, token abuse, rate‑limit evasion, and DRM bypass techniques, attackers can extract protected content at scale. If you can create or compromise enough accounts and make them appear legitimate, you can chip away at content protections over time.

The “Spotify scrape” will likely be framed as a copyright story. But from a security angle, it serves as a reminder: if a platform exposes content or metadata at scale, someone will eventually automate access to it, weaponize it, and redistribute it.

And hiding behind violations of terms and conditions—which have never stopped criminals—is not effective security control.

How does this affect you?

There is currently no indication that passwords, payment details, or private playlists were exposed. This incident is purely about content and metadata, not user databases. That said, scammers may still claim otherwise. Be cautious of messages alleging your account data was compromised and asking for your login details.

Some general Spotify security tips, to be on the safe side:

• If you have reused your Spotify password elsewhere or shared your credentials, consider changing your password for peace of mind.
• Regularly review active sessions on streaming services and revoke anything you do not recognize. Spotify does not offer per-device session management, but you can sign out of all devices via Account > Settings and privacy on the Spotify website.
• Avoid unofficial downloaders, converters, or “Spotify mods” that ask for your login or broad OAuth permissions. These tools often rely on the same kind of scraping infrastructure—or worse, function as credential-stealing malware.
