Members of Anonymous recently hacked the Web site of HBGary Federal, which has been working with the FBI to identify Anonymous' leaders. The Twitter account of company CEO Aaron Barr was also compromised.

"HBGary Federal's domain names hbgary.com and hbgaryfederal.com, which have since been released, and its Web site, which has since been taken offline, were all hacked in the attack," writes CNET News' Lance Whitney. "Anonymous replaced the site with a page describing its motives behind the attack. In its message, the group claims that documents uncovered by HBGary purporting to reveal the names of the "higher-ups" at Anonymous had incorrect information."

"In addition to defacing the Web page, Anonymous downloaded more than 60,000 of the company's e-mails, which it then posted to the Pirate Bay file-sharing site along with its statement touting its attack against the security firm," Whitney writes.
