Scenario:This year's contest is going to be totally radical! We are like, totally psyched to be partnering with the Password Village this year. I kid you not, the contest is going to be so easy that even an airhead or a jock could crack these passwords! PYSCH! The challenges are going to be bodacious and like totally dope. This year, it is not about wordlists, rules, patterns, or about forensics. In the past we've asked our teams how passwords have changed over time... now we are going to ask them to go back, to the future of password cracking. Like, totally.
Logistics:Prior to the start of the contest, KoreLogic will disseminate large encrypted file(s), that teams should pre-download. The decryption key(s) will be published once the contest starts.
More files might be released once the contest starts.
The passwords will range from being "easy" to extremely difficult to crack. 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.
If you are entirely new to password cracking, check out the Password Village at DEF CON, and then come back.
What to Submit: There will be differences in what Pro and Street teams should crack; more details will be published before the contest starts, but generally speaking teams should only spend effort cracking and submitting the hashes for their class of competitor.
The goal of the contest is simple: score the most points.
Types of Teams:You have a choice of how you compete:
- "Pro" Teams: Teams of people who want to compete for
all the glory of being the best password cracking team on the
- "Street" Teams: Individuals or groups who are more casual.
People who want to play around, small teams of 1-3 people who
want to compete but don't want to be competing with the "big
guns". Or big GPUs, whatever the case may be.
Scoring Points:Points are earned by cracking hashes and submitting plaintexts.
Teams should plan to submit their new cracks often / promptly, and check the stats page (once available) frequently.
Teams are encouraged to pre-register. See the registration HOWTO for instructions on generating a PGP keypair and registering a team. (Note, registration is not yet open.)
Rules:For everyone competing, besides following the directions about how to register and submit:
- You MAY use as many systems/cores/GPUs/CPUs as you wish.
- You MAY use systems NOT located at DEF CON.
- You MAY work with other team members not attending DEFCON.
- You MUST ONLY use systems that you are authorized to use.
- You MUST NOT attempt to gain unauthorized access to any system used by KoreLogic or another team.
- You MUST NOT attempt to interfere with the efforts of another team.
- You MUST NOT attempt to steal passwords from or techniques/methods used by another team.
- You MUST NOT be on multiple teams or switch teams during the contest - we will assume you stole all the cracks from one or the other.
- KoreLogic employees are not eligible for the contest.
- To be eligible to be named as a "Winner", you MUST agree to share your
techniques / methodologies and describe the resources/tools
used to crack the passwords afterwards.
- Pro teams' roster of members must be FIRM before the
start of the contest. There is NO trading of plain-texts
Any violation of the rules can result in immediate disqualification from the contest. Any illegal activity will be reported.
Differences from previous contests:Watch this space :)
Results:During the contest, KoreLogic will publish status and statistics.
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.
We invite all teams that participate to write up a post-event report. The teams with the most points will be required to write up their techniques/methodologies, describe the resources/tools used to crack the passwords, and describe any lessons learned, in order to be officially declared winners.
After the contest concludes, KoreLogic will:
- Announce the winners.
- Release some details about the plaintexts' composition.
- Provide statistics on successful cracks.
