Description

AWS EBS discovery operation.

Attacker's Goals

  • Locate valuable data, understand storage configurations, and identify snapshots that can be copied or shared.
  • Support data exfiltration, lateral movement, or persistence through volume or snapshot manipulation.

Investigative actions

  • Verify if the identity typically queries EBS volumes or snapshots in this environment.
  • Check whether this activity is part of expected workflows (e.g., backup validation, provisioning) or appears anomalous.
  • Review surrounding activity for other discovery calls to assess broader enumeration behavior.
  • Examine whether the activity was followed by potential exfiltration steps, such as copying a snapshot cross-region or sharing it externally.
