Description

Identifies when new Service Principal credentials have been added in Microsoft Entra ID. In most organizations, credentials will be added to service principals infrequently. Hijacking an application (by adding a rogue secret or certificate) with granted permissions will allow the attacker to access data that is normally protected by MFA requirements.

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.

Known benign triggers

  • Service principal credential additions may be done by a system or network administrator. Verify whether the username, hostname, and/or resource name should be making changes in your environment. Credential additions from unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
