Following up on attacks on Sony, InfraGardPBS and a slew of other sites, the hacker group Lulz Security penetrated the website belonging to the U.S. Senate. On its site, the group says: "We don't like the U.S. government very much," and posts a list of file names it says were pilfered from Senate computers. However, in a statement, the Senate Sergeant at Arms Office said Lulz only penetrated a section of the upper chamber's site for public information and was "only able to read and determine the directory structure of the files placed on" No individual user account information was compromised, the office said.
