Reversing 550: assembly-4

Challenge
Can you find the flag using the following assembly source? WARNING: It is VERY long…

Solution

They give us enough to compile it, so, we just do that. Most online compilers
are x64 for some reason, so compiling locally is a bit easier:

1
2
3
4

$ nasm -f elf32 comp.nasm
$ gcc -m32 comp.o -o comp
$ ./comp
picoCTF{1_h0p3_y0u_c0mP1l3d_tH15_94698637933

There’s some garbage at the end, just add a } and remove digits until it goes
through. I don’t know when precisely it went through but it’s something like
that.
