The U.S. Senate website was the latest target in a string of cyberattacks from Lulz Security, the hacker group that had previously compromised PBS and some Sony sites. The hackers got into the servers’ public side but were not able to penetrate the firewall to reach private information, such as senators’ contact information. "We don't like the U.S. government very much," Lulz Security said in its release of the information it obtained. "This is a small, just-for-kicks release of some internal data from Senate.gov—is this an act of war, gentlemen? Problem?" The reference is to a report that the U.S. government may consider cyberattacks acts of war; however, the report referred specifically to attacks from foreign governments, not loose-knit hacking groups like Lulz Security.
