Members of Anonymous recently released additional information stolen from security think tank STRATFOR.

"The data purports to be the names and credit-card numbers of people who have purchased research from Stratfor plus hundreds of thousands of user names and e-mail addresses used to register with the website," writes Computerworld's Jeremy Kirk.

"The data comprises 75,000 names, credit card numbers and MD5 hashes, or cryptographic representations, of passwords for people who have paid Stratfor for research," Kirk writes. "The group also said the data contains 860,000 user names, e-mail addresses and MD5 hashes for passwords for anyone who has registered on Stratfor's website."
