A simple proof of concept shellcode injector using syscalls.
https://www.solomonsklash.io/syscalls-for-shellcode-injection.html
Currently works for Windows 10 1909 and 2004, with 1909 as the default. You'll need to uncomment the syscall for 2004 in Syscalls.cs and comment out the syscall for 1909 to switch to 2004.
This POC was inspired by Jack Halon and his Utilizing Syscalls in C# series as well as badBounty's directinjectorPOC. Thanks to both!
