## What it is
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
