    ATT&CK tactics: Initial Access (TA0001) Credential Access (TA0006)
    ATT&CK techniques: Valid Accounts: Cloud Accounts (T1078.004) Steal Application Access Token (T1528) Unsecured Credentials (T1552)
    Required data: AWS Audit Log
    Attacker's goals: Exfiltrate token and abuse it remotely.
    Investigative actions: Verify whether the compute-attached identity's credentials were intentionally used remotely. Check what API calls were executed using instance's attached role. Check if the suspected instance is compromised.
