By overriding the default command specified in a pre-approved job definition, an attacker can bypass static configuration reviews and infrastructure-as-code (IaC) drift detection tools. Because the underlying job definition remains unchanged, this technique is highly stealthy and allows for the injection of malicious payloads, shell commands, or exfiltration logic into legitimate Batch compute environments.\u003c/p\u003e\n\u003cp\u003eDefenders should monitor AWS CloudTrail logs for \u003ccode\u003eSubmitJob\u003c/code\u003e events where the request includes container overrides.
