TikiTorch: Process Hollowing

TikiTorch was named in homage to CACTUSTORCH by Vincent Yiu. The basic concept of CACTUSTORCH is that it spawns a new process, then uses CreateRemoteThread to run the desired shellcode within that target process. Both the process and shellcode are specified by the user.

This is pretty flexible as it allows an operator to run an HTTP agent in a process such as iexplore.exe, rather than something more arbitrary like rundll32.exe.

TikiTorch follows the same concept but uses Process Hollowing techniques instead of CRT.

Usage

TikiTorch is a Visual Basic solution, split into 6 projects.

• TikiLoader
• TikiSpawn
• TikiSpawnAs
• TikiSpawnElevated
• TikiCpl
• TikiThings

TikiLoader

  -u, --username=VALUE       Username

  -p, --password=VALUE       Password

  -b, --binary=VALUE         Binary to spawn & hollow

  -h, -?, --help             Show this help

TikiSpawnElevated

A .NET exe used to spawn a high integrity agent using the UAC Token Duplication bypass.

> TikiSpawnElevated.exe

  -b, --binary=VALUE         Binary to spawn & hollow

  -p, --pid=VALUE            Elevated PID to impersonate (optional)

  -h, -?, --help             Show this help

TikiCpl
