Hackers caught stealing Claude subscription tokens from users

A Claude subscriber noticed his account consuming tokens even though he wasn't using it, TechCrunch reports. Anthropic has since warned users that hackers are targeting subscriber accounts to siphon usage.

Why it matters: AI subscriptions now carry real monetary value in token allowances, making them an attractive target for account-takeover attacks similar to those long seen in gaming and cloud-compute credentials. Expect more AI providers to add anomaly detection and forced re-authentication as token theft becomes a recognized abuse vector.
