|Team hashcat has won CMIYC 2014!||

Note: The contest has ended!
As a part of authorized penetration tests of companies' internal corporate networks and external e-commerce websites, you have captured a large number of password hashes, and some encrypted files of various types. The hashes are from Active Directory, UNIX systems, LDAP servers, various web application and/or forums, routers, etc. As part of your analysis, your client has asked for password complexity statistics, what their users are doing right and/or wrong related to generating passwords, and identification of weak passwords. You only have 48 hours to complete this effort.
Prior to the start of the contest, KoreLogic will disseminate a set of files encrypted with a long random string as direct downloads, torrents, or both. Once the contest starts, KoreLogic will publish the decryption string to unpack the files. This way, competitors can pre-download the contest files (some of which may be quite large) so that they are ready to go when the contest starts.
These will contain files of hashes of various types, and also various encrypted files (challenges / hints). Hashes will be things like MD5, Salted MD5s, Blowfish, SHA1, SHA256, SSHA, DES, MD5(md5), NTLM, etc. Challenge files could be any kind of encrypted container file, or system OS image that you must figure out how to extract hashes from, etc.
The passwords will range from being "easy" to extremely difficult to crack. They are not simply randomly generated passwords, which would favor only the person or group with the most GPU/CPU bruteforcing horsepower. Instead, the password files contain passwords based on what we believe are challenging real-world patterns. Passwords will be of varying lengths, patterns, and complexity. Creative password cracking techniques, rules, dictionaries, and tools will be needed. The teams who are smart about the methods they use (i.e., teams who can crack more, with less work) will most likely be the most successful.
Challenge files are worth points for cracking, just like password hashes.
The goal of the contest is simple: score the most points.
Types of Teams:
You have 2 choices in choosing how you compete:
Pro Team Pre-Contest Task
Note: Pro teams should register as soon as possible.
At 11:59:50 PM PDT on July 17th, a pre-contest task was sent privately to all registered Pro teams which was due on July 31st, one week before the start of the contest. Teams could still register as Pro after the 17th, but they then had less time to complete the pre-contest task. (It should not take all two weeks to do, and was not necessarily computationally-intensive.)
Differences from the 2013 Contest:
Please note the following differences from the 2013 contest:
During the contest, KoreLogic will publish updated scores as often as possible.
After the contest ends, KoreLogic staff will validate each submission and will announce the winning teams on Sunday, (time TBD, but certainly before the DEFCON C&E Awards Ceremony). The eligible team with the highest score will be the winner. If there is a tie in total points, the team that submitted their entry first will place higher.
The winning teams will be required to write up their techniques / methodologies, describe the resources/tools used to crack the passwords, and describe any lessons learned.
At the conclusion of the contest, KoreLogic will:
KoreLogic will be giving away the following prizes for first, second, and third place in the "Professional" Devision:
