Yeah, let's make the challenge binary use so much memory the computer thrashes so badly that stopping the binary takes 10 minutes. GREAT FUCKING IDEA.

@NieDzejkob I don't think you understand the idea of Reverse Engineering. Running ANY binary provided at a CTF without a proper sandbox and debugger attached, or before thorough static analysis is a suicide. You do realize that in many cases those binaries are malware-like and can cause harm? You should be happy that in this case it only caused memory swapping...

1. Disable swap, it's a disaster on Linux systems anyway. Just let OOM killer do its work.
2. @Pharisaeus has a point. Malware-like or harmful binaries are not the norm on CTFs, but they do happen. Swapping for a minute because you misconfigured your system is peanuts in comparison. You should always exercise extreme caution when running an untrusted binary - *especially* during CTFs.
3. Even if true, that was the least important problem during the CTF (for example, as far as I know, 3 tasks out of 4 were broken at the beginning :P).
