In the early 2000s, when video games weren't protected against DLL injection hacks, I spent a lot of time writing DLL injectors for fun and learning.
The line I used in every experiment was:
`jmp $` (or `EB FE` in machine code)
It was the shortest infinite loop in x86 assembly, equivalent to `while 1: ;`
I would create a minimal DLL with this assembly code, inject it into games like Battlefield 1942, and observe it in OllyDbg. The injected DLL would then start on a new thread and access all the game data in memory.
Brought back a lot of memories.
