Get-InjectedThreadEx – Detecting Thread Creation Trampolines

This report analyzes how memory-resident malware can evade thread-creation detections by using four trampoline classes—inline hooks, thread-context hijacks/APC (illusionary trampolines), in-image gadgets, and legitimate library functions repurposed as trampolines—and presents detection strategies and an updated PowerShell tool (Get-InjectedThreadEx) that inspects thread start addresses, CFG bitmap state, working set sharing, call-stack anomalies, and byte-pattern heuristics to hunt for suspicious thread creations.
