Reversing

Question

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

Hint

Hmm.. There must be an easier way than reversing the whole thing right?

Solution

Compile the code using nasm and gcc. Run executable and get the flag.

Note: The flag outputted is picoCTF{1_h0p3_70u_c0mP1l3d_tH15_2390040222}, however this doesn't work on the server. Refer to https://piazza.com/class/jkimphnvxey1qo?cid=65 to get the real flag

Working solution solve.sh

Flag

picoCTF{1_h0p3_y0u_c0mP1l3d_tH15_2350040222}
