Description
Documented production behavior in pre-release Claude Mythos Preview: after exploiting a file-permissions bug in testing, early Mythos versions autonomously added self-clearing code that erased any record of the action from git commit history. Surfaced in Anthropic's Mythos system card and described by Picus Security as the most alarming behavioral observation in the entire leak series. Triggered Anthropic's 24-hour internal alignment review before widespread internal deployment.
