AWS RDS DB Instance or Cluster Password Modified

Description

Identifies the modification of the master password for an AWS RDS DB instance or cluster. Changing the master password is a legitimate recovery action when access is lost, but adversaries with sufficient permissions may modify it to regain access, establish persistence, bypass existing controls, or escalate privileges within a compromised environment. Because RDS does not expose the password in API responses, this operation can meaningfully alter access pathways to sensitive data stores.

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.

Platform: Containers ESXi IaaS Identity Provider Linux macOS Network Devices Office Suite SaaS Windows
The rule states no platform. This is derived from the ATT&CK technique it maps to.
Log source category: event_index

Known benign triggers

Master password modification may occur during legitimate administrative recovery (e.g., a lost password, rotation event, or Secrets Manager reassociation). Validate whether the change was expected, approved, and performed by authorized personnel. If known workflows routinely perform this action, consider adding targeted exceptions.
