The group, which calls itself "Lulzsec," is the same group that posted fake news stories on PBS.com
over the weekend.
They have been promising Sony attacks since this past weekend, a plan they called "the beginning of the end"
for Sony. After being challenged to show what they found, the group today posted links on Twitter
to samples of information they compromised on internal Sony networks and Web sites, including Sony Pictures, Sony Music Belgium, and Sony Music Netherlands.
On the site Pastebin, Lulzsec wrote
: "We recently broke into SonyPictures.com and compromised over 1,000,000 users' personal information, including passwords, email addresses, home addresses, dates of birth, and all Sony opt-in data associated with their accounts. Among other things, we also compromised all admin details of Sony Pictures (including passwords) along with 75,000 'music codes' and 3.5 million 'music coupons'."
The group said they didn't have the resources to copy all the information found, but is posting "samples" to prove their authenticity. The group claims they could have taken more, but that would have taken "several more weeks."
The files in the download appear to contain names, addresses, e-mail addresses, and passwords, but it was unclear how many were in the sample provided by the group.
One file labeled Sony BMG Music Entertainment Belgium included this note: "This target gave us LOLs as it provided internal release dates of records, barcodes, sales reports, and plaintext Sony employee passwords."
Sony did not immediately respond to a request for comment.
