Description
Detects when an Amazon Elastic Block Store (EBS) snapshot is shared with another AWS account or made public. EBS snapshots contain copies of data volumes that may include sensitive or regulated information. Adversaries may exploit ModifySnapshotAttribute to share snapshots with external accounts or the public, allowing them to copy and access data in an environment they control. This activity often precedes data exfiltration or persistence operations, where the attacker transfers stolen data out of the victim account or prepares a staging area for further exploitation.
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.
