VirtualAlllocEx / DEFCON-31-Syscalls-Workshop
Contains all the material from the DEF CON 31 workshop "(In)direct Syscalls: A Journey from High to Low".
Language:C 695 The following two code samples can be used to understand the difference between direct syscalls and indirect syscalls
Language:C 208annihilatorq / shadow_syscall
windows syscalls with a single line and a high level of abstraction. has modern cpp20 wrappers and utilities, range-based DLL and export enumeration, wrapper around KUSER_SHARED_DATA. supported compilers: clang, gcc and msvc
Language:C++ 175Start with shellcode execution using Windows APIs (high level), move on to native APIs (medium level) and finally to direct syscalls (low level).
Language:C 141voidvxvt / HellBunny
Malleable shellcode loader written in C and Assembly utilizing direct or indirect syscalls for evading EDR hooks
Language:C 121This code example allows you to create a malware.exe sample that can be run in the context of a system service, and could be used for local privilege escalation in the context of an unquoted service path, etc. The payload itself can be remotely hosted, downloaded via the wininet library and then executed via direct system calls.
Language:C 54Fadouse / BypassETWDirectSyscallShellcodeLoader
BypassETWDirectSyscallShellcodeLoader is a robust C++14 application designed for secure and stealthy shellcode execution. It incorporates advanced anti-debugging and anti-sandboxing techniques to evade detection and analysis, making it suitable for penetration testing and security research.
