Detects an unusually high number of successful Claude chat snapshot creation events for the same user email within a rolling 24-hour window. Chat snapshots package conversation content into shareable exports; sustained creation volume can indicate staging of organizational chat data for exfiltration via Anthropic's web service or automated bulk export of sensitive prompts and responses.

Starting an organization data export only signals intent. Accessing the export archive via its signed URL means the actor actually downloaded chats, projects, user metadata, and configuration. An attacker with administrative access can use this to exfiltrate intellectual property and credentials at scale.

Attackers leverage GenAI agents to systematically locate and exfiltrate credentials, API keys, and tokens. Access to credential stores (.aws/credentials, .ssh/id_*) suggests harvesting, while writes to shell configs (.bashrc, .zshrc) indicate persistence attempts. Note: On linux only creation events are available. Access events are not yet implemented.
