Description

AWS Lambda discovery operation.

Attacker's Goals

  • Enumerate functions, gather configuration and trigger details, and identify attached roles or permissions.
  • Assess potential entry points, understand execution context, and plan privilege escalation or function tampering.

Investigative actions

  • Verify if the identity is expected to access Lambda configuration or code metadata.
  • Check if this API call was part of a broader enumeration pattern.
  • Determine whether the activity aligns with typical deployment or monitoring behavior, or if it appears manual or anomalous.
  • Investigate whether this was followed by any actions that could indicate lateral movement.
