A small shellcode loader library written in C# This small library allows you to inject shellcode in memory of current launched file. Useful to use as red team or in a remote access tool.
I added some test payloads which I've converted with
- First with : Donut (https://github.com/TheWover/donut) : turns my payload into raw shellcode
- Second with HxD Editor (https://mh-nexus.de/en/downloads.php?product=HxD20) : gives me an array of raw bytes from payloads converted with Donut
Includes :
- Asynchronous (a simple Task.Run to not block main thread)
- Loading with Kernel32
- Loading with NtDll
- NtDll : NtAllocateVirtualMemory
- NtDll : NtWriteVirtualMemory
- NtDll : NtProtectVirtualMemory
- NtDll : NtFreeVirtualMemory
- Kernel32 : GetCurrentProcess
- Kernel32 : VirtualAlloc
- Kernel32 : VirtualFree
- Kernel32 : VirtualProtect
- Kernel32 : WriteProcessMemory
- Enumeration : PageProtection
- Enumeration : TypeAlloc
- Enumeration: FreeType
TODO :
- Inject shellcode in another process with VirtualEx and NtEx functions
- Check if shellcode is 64 or 32 bit before injection
Known :
- Debugging 32 bit test injection involves PInvokeStackImbalance
