The disbanding of Lulzsec has coincided with hacking brotherhood Anonymous releasing another set of files which includes documents and links to security and hacking resources on the internet, many of them free, various template letters, hacking and counter hacking tools as well as the addresses of FBI bureaus in the US.
The 625MB file (SENTINEL Security Utilities - Cyberterrorism Defense and Analysis Center) is now widely available online and seems to have come from the US FEMA (Federal Emergency Management Agency) Counter Terrorism Defence Initiative training program.
Anonymous linked to the CDI SENTINEL program page but they haven't confirmed whether the file actually comes from there. The site says that SENTINEL provides free cybersecurity training "directly to centralized rural and metropolitan areas of critical need across the country" using a mobile computer lab. It is likely that one of these might have been compromised or even stolen.
After having announced that it's leaving the scene, Lulzsec encouraged its Twitter followers to follow the @AnonymousIRC account. Anonymous picked up more than 60,000 followers in the last few 24 hours or so helping them to shatter then 100,000-follower barrier.
Anonymous has also posted a 457MB file called "50 days of Lulz" on Piratebay which contains all the files and releases over the last seven weeks including some AOL internal data as well as tens of thousands of user details from a number of e-commerce websites, hackers and gaming forums (ed: the original file disappeared from Piratebay because it contained some malware targeting Windows, it has now been replaced by a smaller, clean one).
They are also promising more on the way having claimed that they found a huge chest of 40TB worth of internal data from some "evil company" (ed: Microsoft maybe ;-) before adding that they're not sure how to "carry" it given that downloading these files would take weeks, if not- months.
The legacy of Lulzsec's hack blitz will live on for years with companies that have suffered from the hacks likely to bear the scars of the attacks forever. For the rest of us, Lulzsec could even be seen as a blessing in disguise as it has brought online security well and truly back into the limelight.
