THE blog post discusses a warning from Anthropic about cybercriminals using infostealer malware to hijack Claude accounts. Instead of traditional methods such as password guessing, these attackers steal active browser sessions to access users' accounts, draining their usage and financial resources. Anthropic has taken steps to safeguard affected users by signing them out, removing saved payment methods, and addressing unauthorized charges.
Users are advised to secure their accounts by removing malware, enabling two-factor authentication, and changing sensitive passwords. The motivations behind these attacks include using paid Claude capacity without authorization and potential data exploitation.
