Description

Detects the rare occurrence of a user or role accessing AWS Systems Manager (SSM) inventory APIs or running the AWS-GatherSoftwareInventory job. These APIs reveal detailed information about managed EC2 instances including installed software, patch compliance status, and command execution history. Adversaries may use these calls to collect software inventory while blending in with legitimate AWS operations. This is a New Terms rule that detects when a user accesses these reconnaissance APIs for the first time.

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

  • Legitimate administrators or automation tools may access SSM inventory APIs for asset management or compliance purposes. Verify whether the user identity should be using these APIs. If known behavior is causing false positives, add exceptions.
