Their recents exploits include hacking FBI affiliate Infragard (Atlanta Chapter).  They defaced the website, stole account information, and messed with their users.  Particularly Karim Hijazi of Unveillance.  LulzSec alleges that Karim (in a chat on IRC) offered them money and information to hack and his competition in the security industry.  This kind hypocritical behavior is specifically deplored by hackers.  Hijazi’s company email was posted online and in LulzSec’s official statement they threaten the release of his personal email as well.  LulSec started taking donations with BitCoin.  They used some of the money to pay for servers and their “lulzsecurity.com” domain which appears at present to be down.
