By Andrew Morse and Ian Sherr, Of DOW JONES NEWSWIRES SAN FRANCISCO -(Dow Jones)- A hacker group that has claimed attacks on media and law enforcement affiliates extended its month-long cyber rampage on Monday, boasting that it had cracked the U.S. Senate’s website.
On Monday, the group–known as Lulz Security–posted a configuration file for the Senate’s main website on its homepage. The material in the file doesn’t suggest sensitive information was breached, but it does indicate Lulz Security infiltrated the Senate’s network.
“This is a small, just-for-kicks release of some internal data from Senate.gov,” Lulz Security said in its release. “Is this an act of war, gentlemen?”
The group appeared to be referencing a recent Wall Street Journal article that reported the Pentagon considered some forms of computer sabotage constituted warfare.
A Senate representative said she was unaware of any breach of the body’s web site.
The intrusion is part of a spree of hacks by the group, which has targeted Japanese media-and-technology giant Sony Corp. (SNE, 6758.TO), the Atlanta chapter of Federal Bureau of Investigation affiliate InfraGard and U.S. public broadcaster PBS.
Also on Monday, LulzSec, as the group sometimes refers to itself, said it had broken into a website run by Bethesda Softworks LLC., which makes horror and fantasy games.
Bethesda acknowledged its network had been breached but said that no personal financial information or credit card data had been stolen.
“The hackers may have gained access to some user names, email addresses, and/ or passwords,” the company said. “As a precaution, we recommend that all our fans immediately change passwords on all our sites.”
