Informational

Description

An identity allocated multiple compute resources.

Attacker's Goals

Leverage cloud compute resources to earn virtual currency.

Investigative actions

  • Check the identity created resources and its legitimacy.
  • Look for any unusual behavior originated from the suspected identity, and check if they're compromised, e.g. Access key, Service account, etc.
