Stratfor's CEO, George Friedman, wrote on the company's Facebook page on Monday that the intrusion revealed the names of some corporate subscribers along with personal and credit card data.

A first batch of data was released by hackers shortly after the breach. Stratfor denied the hackers' claim that data was a list of "private clients" but rather a list of members who may have purchased a publication.

Barrett Brown, a de facto spokesman for Anonymous, wrote on Pastebin on Monday that the hacking wasn't aimed at stealing credit card numbers but rather 2.7 million internal e-mails.

"This wealth of data includes correspondence with untold thousands of contacts who have spoken to Stratfor's employees off the record over more than a decade," Brown wrote. "Many of those contacts work for major corporations within the intelligence and military contracting sectors, government agencies and other institutions."

Those e-mails have yet to be released and could present another headache for Stratfor. The company's website was still down as of Friday, and officials could not be immediately reached by phone.
