BSidesChicago CTF: Hashes

BSides Chicago CTF Hashes Challenge

This is a write up for the "Hashes" challenge which was rated as moderate difficult. We were given the following LM hashes in a text file:

389121516173B5F9B343EE1EAD7651B1
31C63AD76B4872142C40474FAF5D2BD6
8EF4B5254FAC7DAED2D88E7184DE2905

In the past, I've used a python script called findmyhash to query online rainbow tables to crack LM hashes. This script no longer works so I wrote a script in python to query the ophcrack LM/NTLM rainbow tables. The output is show below via ascii.io. Sorry the write up is short, but this was an easy one.

  2. We cannot stick to the same instructions to access the table. This version is outdated. Now we must use the other way during the request.
