OpenCode Hacked: User credentials leaked
Anomaly Innovations disclosed a security breach affecting its OpenCode Console coding agent product, describing it as a 'large scale distillation attack' that impacted 1.4% of users and leaked their credentials. The company notified affected users by email and is working with Anthropic, OpenAI, and Google to remediate the incident, which it describes as ongoing.
Why it matters This is a concrete, disclosed breach rather than speculative risk: a popular coding-agent platform suffered a credential-exposing attack tied to model distillation, and the fact that three frontier labs are jointly involved in remediation signals the incident reaches beyond a single vendor's infrastructure. It underscores how AI coding agents and their API key management have become a high-value attack surface, with real consumer data at stake rather than theoretical vulnerabilities.
What to watch Watch for Anomaly Innovations' full incident report and whether Anthropic, OpenAI, or Google disclose their own exposure or policy changes around API key handling for third-party agent platforms.
