Time Travel Triage: An Introduction to Time Travel Debugging using a .NET Process Hollowing Case Study

This report demonstrates how Microsoft WinDbg's Time Travel Debugging (TTD) can accelerate analysis of obfuscated multi-stage .NET droppers by allowing analysts to record and replay execution to rapidly locate key API calls and payload delivery events. Using a case study of a .NET dropper that performs process hollowing (with InstallUtil.exe observed as a suspicious child process), the write-up explains TTD's advantages, limitations, and how it helps bypass layers of .NET obfuscation to surface injection and shellcode-related behaviors.
