If you use an Android phone, this deserves your attention. 

Cybersecurity researchers warn that hackers are using Hugging Face, a popular platform for sharing artificial intelligence (AI) tools, to spread dangerous Android malware. 

At first, the threat appears harmless because it is disguised as a fake antivirus app. Then, once you install it, criminals gain direct access to your device. Because of this, the threat stands out as especially troubling. It combines two things people already trust — security apps and AI platforms.

What Hugging Face is and why it matters

For anyone unfamiliar, Hugging Face is an open platform where developers share AI, NLP and machine learning models. It is widely used by researchers and startups and has become a central hub for AI experimentation. That openness is also what attackers exploited. Because Hugging Face allows public repositories and supports many file types, criminals were able to host malicious code in plain sight.

The fake antivirus app behind the attack

The malware first appeared in an Android app called TrustBastion. On the surface, it looks like a helpful security tool. It promises virus protection, phishing defense and malware blocking. In reality, it does the opposite. 

Once installed, TrustBastion immediately claims your phone is infected. It then pressures you to install an update. That update delivers the malicious code. This tactic is known as scareware. It relies on panic and urgency to push users into tapping before thinking.

How the malware spreads and adapts

According to Bitdefender, a global cybersecurity company, the campaign centers on a fake Android security app called TrustBastion. Victims were likely shown ads or warnings claiming their device was infected and were instructed to manually install the app.

The attackers hosted TrustBastion’s APK files directly on Hugging Face, placing them inside public datasets that appeared legitimate at first glance. Once installed, the app immediately prompted users to install a required “update,” which delivered the actual malware.

After researchers reported the malicious repository, it was taken down. However, Bitdefender observed that nearly identical repositories quickly reappeared, with small cosmetic changes but the same malicious behavior. That rapid re-creation made the campaign harder to fully shut down.

What this Android malware can actually do

This Trojan is not minor or annoying. It is invasive. Bitdefender says the malware can:

Take screenshots of your device

Show fake login screens for financial services

Capture your lock screen PIN

Once collected, that data is sent to a third-party server. From there, attackers can move quickly to drain accounts or lock you out of your own phone.

What Google says about the threat

Google says users who stick to official app stores are protected. A Google spokesperson told CyberGuy, “Based on our current detection, no apps containing this malware are found on Google Play.

“Android users are automatically protected against known versions of this malware by Google Play Protect, which is on by default on Android devices with Google Play Services.

“Google Play Protect can warn users or block apps known to exhibit malicious behavior, even when those apps come from sources outside of Play.”

How to stay safe from Hugging Face Android malware

This threat is a reminder that small choices matter. Here is what you should do right now:

1) Stick to trusted app stores

Only download apps from reputable sources like Google Play Store or the Samsung Galaxy Store. These platforms have moderation and scanning in place.

2) Read reviews before installing

Look closely at ratings, download counts and recent comments. Fake security apps often have vague reviews or sudden rating spikes.

3) Use a data removal service

Even careful users can have personal data exposed. A data removal service helps remove your phone number, email and other details from data broker sites that criminals rely on. That reduces follow-up scams, fake security alerts and account takeover attempts.

While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. 

These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

4) Run Play Protect and use strong antivirus software

Scan your device regularly with Play Protect and back it up with strong antivirus software for added protection. Google Play Protect, which is built-in malware protection for Android devices, automatically removes known malware. However, it is important to note that Google Play Protect may not be enough. Historically, it hasn’t been 100% effective at removing all known malware from Android devices.

The best way to protect yourself against malicious links that install malware and potentially access your private information is to have strong antivirus software installed on all your devices. This protection can also help you detect phishing emails and ransomware, keeping your personal information and digital assets safe.

5) Avoid sideloading APK files

Avoid installing apps from websites outside the app store. These apps bypass security checks, so always verify the publisher name and URL.

6) Lock down your Google account

Your phone security depends on it. Enable two-step verification (2FA) first, then use a strong, unique password stored in a password manager to prevent account takeovers.

Next, see if your email has been exposed in past breaches. Our No. 1 password manager (see Cyberguy.com) pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

7) Be cautious with permissions

Be cautious with accessibility permissions. Malware often abuses them to take control of your device.

8) Watch app updates closely

Malware can hide inside fake updates. Be cautious of urgent fixes that push you outside the app store.

Kurt’s key takeaways

This attack shows how quickly trust can be weaponized. A platform designed to advance AI research was repurposed as a delivery system for malware. A fake antivirus app became the threat it claimed to stop. Staying safe no longer means avoiding sketchy-looking apps. It means questioning even those apps that appear helpful and professional.
