According to CoinMeta, on November 2nd, Gitbook suffered a cyberattack driven by AI. The attackers gained unauthorized access to some infrastructure credentials. Gitbook immediately detected the attack and took measures to take down applications and documentation websites that required authentication to ensure security. By 4:21 p.m. on November 3rd, the applications, API, and the published documents were restored to availability. Gitbook stated that this intrusion was a complex and highly targeted attack, and the attackers were stopped with all credentials being replaced. The investigation found that the information that may have been accessed included integration tokens, Git synchronization keys, and API tokens. Gitbook has invalidated the customers' API tokens and requested that customers replace their credentials.
