The day after Christmas, Anonymous released 13.000 credit card numbers and account details from popular websites. But the analysis of the package by security experts shows that most of these items have been available online for a long time.
The post was made "for Lulz", according to an account by Anonymous on Twitter. It contained passwords for Amazon, Wal-Mart, and Hulu Plus, as well as accounts from other software and pornography sites. There were also some credit card details.
Ken Westin, senior security analyst at Tripwire, analyzed the leaked data, and says there's nothing to worry about.
"A lot of that data is from 2011 and 2012 and I couldn't find anything particularly new," Westin told TheRegister. "I also doubt that they were actually released by Anonymous. It does not look like something they are used to doing. "Usually when they publish data they do it for a specific purpose, not just for fun."
The bulk of the leaked data, he said, was accounts usernames and passwords that mostly come from a website called Leakforums.net, which is used to posting stolen accounts. Credit card information is very old, he added.
So far, none of them Companies whose data was allegedly leaked reported any hacking activity on their servers.
