CSAW CTF 2014 is the second CTF contest I've attended ( the first one was the HITCON CTF 2014 ) . Since this is the first time I've actually solved something in the contest, I decide to post my first own writeup .

First the challenge gave us a binary file (ELF for Intel-386). But we can't execute it, cause we don't have the required shared library "libchallengeresponse.so". So we will have to launch IDA Pro to see what's going on within the program.

This challenge gave us a NES ROM. After we launch it with NES debugger FCEUX, we found out that it eventually want us to input a password with 24 characters in length .

Here they gave us another 64 bit ELF, which is apparently written in C++.
