A proof-of-concept tool and technical write-up demonstrating Process Herpaderping, a Windows technique that maps a process image from a file and then rewrites the file on disk before the initial thread runs. This causes security products that inspect the file at process-creation callbacks or IRP_MJ_CLEANUP to attribute the running process to the wrong binary.

Use cases

  • bypass antivirus inspection of newly created processes
  • study how Windows kernel process-creation callbacks can be evaded
  • demonstrate write-map-modify-execute-close evasion of on-write scanning
  • compare herpaderping with process hollowing and doppelganging
  • research security product detection gaps on Windows 7 through Windows 10

When to choose

  • you are a security researcher or red-teamer studying Windows process-creation evasion techniques
  • you need a working reference implementation of Process Herpaderping with a detailed technical explanation
  • you want to test or harden EDR/antivirus inspection at PsSetCreateProcessNotifyRoutineEx and IRP_MJ_CLEANUP

When to avoid

  • you need a general-purpose process launcher or legitimate application tooling
  • you are looking for a cross-platform or non-Windows technique
  • you want a maintained production tool rather than a research proof of concept
