DbgChild is a stand alone tool for debugging child processes. DbgChild can be used in conjunction with a plugin for a debugger. Currently DbgChild supports a plugin for the x86/x64 x64dbg debugger.

https://github.com/David-Reguera-Garcia-Dreg/DbgChild

Features

• Hook process creation for x86 or x64 child processes
  Patching and unpatching of NTDLL process creation for x86 and x64 child processes
  Process watcher for auto launching of new x64dbg instance when child process detected
  Modify the suspend (pre) and resume (post) logic to adapt to your own requirements

The DbgChild comprises a number of components to accomplish the task of launching a new x64dbg instance when a child process is hooked and detected.

These components are:

• CreateProcessPatch.exe - Hook ZwCreateUserProcess (two separate exe files for x86 and x64) and loads DbgChildHookDLL.dll
  DbgChildHookDLL.dll - (two separate dll files for x86 and x64) - outputs process id's to CPIDS folder
  NTDLLEntryPatch.exe - Patches or unpatches LdrInitializeThunk (two separate exe files for x86 and x64)
  DbgChild.dp32 - x64dbg plugin x86
  DbgChild.dp64 - x64dbg plugin x64
  NewProcessWatcher.exe - Watches for new child processes from the CPIDS folder
  x64_post.unicode.txt - Support file
  x64_pre.unicode.txt - Support file
  x86_post.unicode.txt - Support file
  x86_pre.unicode.txt - Support file

You can use it for automate malware analysis, or make a per-process infection....

Also you can replace each component for your own specific component.

WARNING: The code is bullshit and there are some bugs, I know.
