This doesn’t require any fancy analysis. You can literally read the password off it — the last bit is an oddly decompiled string comparison.

Not everybody writes in the language they want to exploit I suppose, that's the great thing about LLMs!

on edit: even though I don't know C or C++ (I suppose it's C but can't be sure) I do think I can figure out what it's doing and how to guess what the password is, so that seems bad.

Well most SWEs need an llm to spell their own name now.
