The detection rule named "Parent Process PID Spoofing" focuses on identifying instances where adversaries may use process manipulation techniques to spoof the Parent Process Identifier (PPID) to obscure the origins of a process, potentially bypassing security measures and gaining unauthorized privileges. The rule is implemented using Elastic Query Language (EQL) and is designated for high-risk circumstances within Windows environments. By leveraging a sequence-based query, the rule monitors the execution of processes initiated on hosts, specifically observing their parent-child relationships while filtering for known benign processes and certain integrity levels. The detection logic scrutinizes the parameters associated with process creation events, particularly watching for anomalies like mismatched parent process IDs, unexpected executable paths, and the presence of unsigned code signatures, all indicative of potential attacks. If triggered, the rule generates alerts for possible parent process spoofing incidents, necessitating further analytical investigation and response actions. Agent-based detections are crucial in ensuring alert precision and reducing false positives. An in-depth triage process enables the identification of benign versus malicious behavior, ensuring comprehensive remediation actions are taken against possible threats to system integrity.
