Detects a ChatGPT Enterprise user issuing ten or more distinct Slack app search queries in a five-minute bucket. Adversaries who abuse a linked Slack connector after session compromise often run rapid multi-query searches across channels and messages to locate sensitive content before collection or exfiltration.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

The rule states no platform. This is derived from the 2 ATT&CK techniques it maps to.

Known benign triggers

  • Approved automation that uses ChatGPT's Slack connector for triage or knowledge lookup. Raise the distinct-query threshold if those roles remain noisy.
  • Incident responders, support engineers, or community managers who run many Slack search refinements in a short window. Validate the query values and business context before escalating.
