Description

Correlates the first occurrence of an Okta user session started via a proxy with subsequent Okta security alerts for the same user.

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.

  • Security testing or red team exercises using proxy infrastructure.
