A fraudulent desktop application impersonating Anthropic’s Claude AI has been identified as a delivery vehicle for RevStealer, a Windows-based information-stealing malware capable of draining cryptocurrency wallets and harvesting sensitive browser and messaging data, according to a report published Monday by cybersecurity firm Morphisec.
The most notable distribution vector is a fake project called ‘Claude Opus 5 Free Desktop,’ which mimics AI developer Anthropic and promises users free access to Claude. Morphisec researchers noted that RevStealer had also previously circulated through GitHub repositories and game-cheat-themed websites before this more sophisticated impersonation campaign emerged.
