    ATT&CK tactics: Initial Access (TA0001) Credential Access (TA0006) Execution (TA0002)
    ATT&CK techniques: Valid Accounts: Cloud Accounts (T1078.004) Steal Application Access Token (T1528) Unsecured Credentials (T1552) Command and Scripting Interpreter: Cloud API (T1059.009)
    Required data: AWS Audit Log
    Detector tags: Cloud Serverless Function Credentials Theft Analytics
    Attacker's goals: Exfiltrate serverless token and abuse it.
    Investigative actions: Verify whether the serverless-attached identity's credentials were intentionally used in CLI. Check what CLI commands were executed using the serverless attached token. Check if the suspected serverless function is compromised.
