GitBook, a documentation platform heavily utilized by cryptocurrency projects, disclosed a security breach on November 2 involving a sophisticated attack using AI agents. The incident allowed an unauthorized actor to gain access to certain infrastructure credentials at 7 p.m. Central European Time. GitBook stated that it detected the intrusion immediately and moved to contain it, subsequently taking its application and authentication-required documentation sites offline while securing its infrastructure.

The company identified several categories of potentially exposed information, including API tokens, integration secrets, Git Sync secrets used for code repository connections, and queries submitted to its AI assistant. Despite the credential exposure, GitBook reported finding no evidence that hosted content had been modified. Publicly available documentation remained accessible through cached copies during the outage. By Tuesday afternoon, GitBook announced that its core services were accessible again, though some functions remained degraded during recovery.

In response to the breach, GitBook revoked personal API tokens and instructed users to rotate existing keys and replace third-party secrets associated with external integrations. Users of the Model Context Protocol (MCP) server were required to re-authenticate. The incident prompted immediate action from major crypto entities; decentralized exchange PancakeSwap temporarily disabled its documentation as a precaution, stating its own systems were not compromised. PancakeSwap later migrated its documentation to self-hosted infrastructure, ensuring links continued to work while warning users that official docs never request wallet connections or token approvals.
