Anthropic reports hackers hijacking Claude user sessions
Anthropic has prompted some Claude users to re-authenticate their accounts after discovering that malicious actors were utilizing stolen browser session data to gain unauthorized access and deplete usage quotas. The company explained that this activity stems from widespread information-stealing malware found on compromised devices. Anthropic noted that individuals who observed their usage limits resetting unexpectedly and then hitting their caps rapidly might have been victims of these account breaches.
