ATT&CK analytic guidance
DET0111 Detect Unsecured Credentials Shared in Chat Messages
AN0309 Analytic 0309
Detection correlates message events in email and collaboration tools (e.g., Outlook, Teams) that contain regex-like patterns resembling credentials, API keys, or tokens. Anomalous forwarding or bulk copy activity of chat/email content containing secrets is flagged. Suspicious behavior includes users pasting secrets into direct messages or attaching config files with passwords.
AN0310 Analytic 0310
Detection monitors SaaS collaboration tools (e.g., Slack, Zoom, Jira) for messages or files containing credential-like patterns, or for suspicious API calls retrieving bulk chat histories by non-admin users. Identifies adversary behavior chains where chat logs are queried via APIs or integration bots to systematically extract sensitive material.

Threat actor context
These are explicit actor-to-technique associations in the existing Threat Matrix snapshot, not attribution of an event or proof that a detector identifies the actor. No tool-to-actor relationship is inferred.
