Description

Identifies when a single user or service principal deletes multiple Azure Storage Accounts within a short time period. This behavior may indicate an adversary attempting to cause widespread service disruption, destroy evidence, or execute a destructive attack such as ransomware. Mass deletion of storage accounts can have severe business impact and is rarely performed by legitimate administrators except during controlled decommissioning activities.

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

  • Infrastructure teams may legitimately delete multiple storage accounts during planned decommissioning, resource cleanup, or large-scale infrastructure optimization. Verify that the deletion activity was expected and follows organizational change management processes. Consider exceptions for approved maintenance windows or automation service principals.
