Spies, Buried Treasure, and Crypto: What More Do You Want?

By -
Wired has a very interesting article talking about the FBI's investigation into the case of Brian Regan, who tried to sell a bunch of classified documents to foreign governments. Here is a link.

The most interesting thing that I took from the article is that either A) The NSA was unable to crack a simple Caesar Cipher (ROT25), or B) they just didn't bother to share the results with the FBI after claiming to make no progress. Honestly I don't know which option would be better...

The RockYou 32 Million Password List Top 100

But first, a quick responses to one of the previous comments, (since it really did merit a front-page post). Tfcx posted: The initial vulnerability was posted 29th November on a hacking forum called darkc0de here: http://forum.darkc0de.com/index.php?action=vthread&forum=11&topic=13082 Thanks, as that really helps narrow down the timeframe, (and reading that post and related posts was interesting if a bit depressing). The hack itself appears pretty straightforward once you see it, (like most things once the solution is presented to you it's easy, but finding it in the first place is hard). I'm still interested in the hacker Igigi, and have been tossing about all sorts of theories; but I'll refrain from posting them here since they are all pure WAGs right now. Now on to the main topic: Per Thorsheim wrote: I would like to see a comparison of Twitters 370 banned passwords against the top 370 or so passwords stolen from rockyou (http://www.techcrunch.com/2009/12/27/twi...

Cracking the MySpace List - First Impressions

Alt Title: An Embarrassment of Riches Backstory: Sometime around 2008, a hacker or disgruntled employee managed to break into MySpace and steal all the usernames, e-mails, and passwords from the social networking site. This included information covering more than 360 million accounts. Who knows what else they stole or did, but for the purposes of this post I'll be focusing only on the account info. For excellent coverage of why the dataset appears to be from 2008 let me refer you to the always superb Troy Hunt's blog post on the subject . Side note, most of my information about this leak also comes from Troy's coverage. This dataset has been floating around the underground crime markets since then, but didn't gain widespread notoriety until May 2016 when an advertisement offering it for sale was posted to the "Real Deal" dark market website. Then on July 1st, 2016, another researcher managed to obtain a copy and then posted a public torrent of then entir...
