The account database info is still currently available through the LulzSec website (though we'd suggest not visiting) -- various folks on Twitter responding to the group claim to have done a variety of things with the information, from having a large pack of condoms delivered to an elderly woman, to one person saying they bilked a PayPal account for £250 ($404).
Earlier this week, the group attacked and successfully took down a handful of game industry websites, including EVE Online, Minecraft and The Escapist. All three sites quickly recovered and have been online since. Microsoft has yet to respond to request for comment on yesterday evening's alleged breach.
Update: Microsoft has released a statement, which states that Xbox Live was not compromised to the best of Microsoft's knowledge, and the logins/passwords were released at random, with people encouraged to try said information on services like Xbox Live (among others). "This group appears to have posted a list of thousands of potential email addresses and passwords, and encouraged users to try them across various online sites like Xbox Live in the event one of the users happens to use the same password and email address combination. At this time we do not have any evidence Xbox Live has been compromised. However we take the security of our service seriously and work on an ongoing basis to improve it against evolving threats."
