PromptSpy is the first known Android malware to integrate generative AI into its execution flow, using Googleβs Gemini model to generate device-specific instructions that help it pin and persist in Recent Apps. The spyware also includes a VNC module for full remote access, can capture PINs and screen activity, and uses invisible overlays to block uninstallation. #PromptSpy #Gemini
Keypoints
- PromptSpy is the first Android malware observed to use a generative AI model (Google Gemini) during runtime.
- The malware sends an XML dump of the screen to Gemini and receives JSON-formatted UI actions to pin the app for persistence.
- It abuses Androidβs Accessibility Service to execute AI-generated actions and loops until the app is locked in Recent Apps.
- PromptSpy contains a VNC module that grants remote screen control, can capture PINs, record unlock patterns, screenshots, and user gestures.
- Removal is hindered by invisible overlay buttons and Safe Mode is required; samples were found on VirusTotal and distribution may have used domains impersonating JPMorgan Chase.
