Fake 'Claude Opus' App Spreads Malware Stealing Crypto and Passwords
A fake 'Claude Opus 5 Free Desktop' application has been spreading RevStealer, a Windows malware strain designed to steal crypto, password and browser data.
According to cybersecurity company Morphisec, RevStealer was previously distributed through GitHub repositories and game-cheat-themed sites, but this new variant impersonates AI developer Anthropic and promises free access to Claude.
The malware searches browser databases, cookies, password-manager records, VPN and remote-access settings, messaging data, screenshots, and selected documents. It also targets over 50 cryptocurrency wallets.
