Cybersecurity researchers are warning about a new Android malware campaign that takes advantage of legitimate AI infrastructure to distribute malicious software, highlighting a growing trend where attackers hide in plain sight by abusing trusted platforms.
According to a recent analysis by Bitdefender Labs, attackers have been using Hugging Face, a popular hosting platform for machine learning models and datasets, to store and deliver malicious Android payloads. This tactic allows malware operators to bypass traditional security filters that are more likely to flag downloads from suspicious or unknown domains.
The campaign begins with a malicious dropper app disguised as a security or protection tool, with victims typically lured through deceptive ads or warnings claiming their device is infected or vulnerable. Once installed, the app presents what appears to be a legitimate system update prompt, mimicking familiar Android and Google Play interfaces.
The dropper then redirects the device to an external resource, the final payload, a remote access trojan (RAT), and is downloaded from a Hugging Face repository, making the traffic appear trustworthy to both users and automated security systems.
Hugging Face is widely used by developers and researchers to share AI models and datasets. Because it is a reputable and heavily trafficked service, downloads from its infrastructure are less likely to be blocked or scrutinized.
Researchers observed that attackers frequently replaced payloads on the platform, generating new malware samples every few minutes. This technique, known as server-side polymorphism, makes it harder for antivirus tools to detect threats using traditional signature-based methods.
Once installed, the malware requests access to Android Accessibility Services, a powerful feature intended to help users with disabilities. When abused, this permission allows attackers to monitor screen activity, capture credentials, display fake login screens, and remotely control the device.
The RAT can impersonate financial and system applications, steal sensitive information, and maintain persistent communication with command-and-control servers used to issue instructions and exfiltrate data.
Users should watch for:
- Apps or ads that claim your device is “infected,” needs cleaning, or needs urgent updates
- Requests for powerful permissions, especially Accessibility access
- Install prompts that appear outside the Google Play Store
As attackers continue to leverage reputable cloud and AI platforms to distribute malware, this campaign highlights the evolving challenges facing mobile security. Trusted infrastructure alone is no longer a guarantee of safety, making user awareness and layered security protections more important than ever.
