Hackers claim break-in of US Senate computers

WASHINGTON - A loosely aligned group of computer hackers calling themselves Lulz Security said they broke into the US Senate's computer network on Monday.
There was no immediate comment by the Senate Sergeant at Arms Office, which oversees the chamber's security.
Lulz Security, who have hacked into Sony's website and the Public Broadcasting System, posted online a list of files that appear not to be sensitive but indicate the hackers had been into the Senate's computer network.
"They certainly demonstrated that they were in and they found the file server," said Stewart Baker, a former cyber official at the Department of Homeland Security.
