Is macOS online?
I revisited another previous project, msnciasm. I hadn’t used it in a while and wanted to again, but it threw up a
The eventual fix was trivial (literally one character):
- mov r14d, [eax] + mov r14d, [rax]
However, I had not touch this particular project or assembly in so long it was daunting to know where to start. Basically like debugging someone else’s code in a language you don’t read. Fortunately, I had done a lot of reverse engineering binaries for Capture the Flag events, that was helpful to get me stepping through the code to troubleshoot and eventually worked out the fix.
Now I had a new problem, OSX is not a thing anymore, this is macOS. Just enough had changed that the binary wouldn’t build. Getting a working compile probably took longer than the actual fix. But got there in the end.
Updated msnciasm project on GitHub.
