OpenCode Reports Possible Exposure of Third-Party API Keys After Legacy System Breach
OpenCode disclosed that an attacker accessed a legacy system on October 16, potentially exposing API keys from external providers that users had stored in the Console. The incident affected only 1.4 percent of Console users, and the targeted system was already undergoing decommissioning. The company described the exposure as possible rather than confirmed and provided no details on the attack vector, duration, or number of keys involved. Some affected users reported unauthorized charges on their provider accounts. OpenCode stated that the incident was limited to keys stored in the Console and did not impact keys saved locally in its command-line or desktop applications. The firm notified impacted users by email on October 17 and is working with Anthropic, OpenAI, and Google. It recommended revoking and rotating exposed keys directly with each provider.
