For learning purposes, I started studying ways of creating my own Cheat Engine for Linux. CE main feature which I aim reproducing is reading and writing to a process memory address space.
After some reading, I reached some options:
- Using
ptrace
- Read/write of
/proc/pid/mem
- Using
process_vm_readvandprocess_vm_writev
The solutions 2 and 3 seem to be unsafe because could cause race conditions (not sure about the third). Solution one could cause anti-cheats to catch the CE since it sends a SIGSTOP? The idea is really to reproduce software that could be used maliciously like CE, so not being caught easily is important.
