A group calling itself Lulzsec took credit for yet another high profile attacks over the weekend, compromising an information sharing program run by the FBI that counts some of the nation's leading security and private sector firms as partners, then publicizing another hack of electronics giant Sony on Monday.
The group, a spin-off of the anarchic hacker collective Anonymous, posted details of both attacks on its Web site and the file sharing site pastebin.com. The hack of Sony spilled what Lulzsec claimes was source code from Sony Computer Entertainment's Developer Network and a network map of Sony BMG. In the case of the FBI program, dubbed Infraguard, the group posed user names and logins for Infraguard members, and internal company e-mail for one Infraguard member, Unveillance.

The FBI did not immediately respond to requests for comment.
