AN1351 Analytic 1351

A process explicitly forges its parent using EXTENDED_STARTUPINFO + PROC_THREAD_ATTRIBUTE_PARENT_PROCESS (UpdateProcThreadAttribute → CreateProcess[A/W]/CreateProcessAsUserW) or other Native API paths, resulting in **mismatched/implausible lineage** across ETW EventHeader ProcessId, Security 4688 Creator Process ID/Name, and sysmon ParentProcessGuid. Often paired with privilege escalation when the chosen parent runs as SYSTEM.
