LulzSec hacks US Senate website, although no data taken

LulzSec continued to push its collective luck over the weekend, breaking into US Senate computers and publishing the directory structure on its website. The move is LulzSec's most brazen yet: breaking into government computers is a serious offense.

The group is responsible for hacks on FBI-related sites and Nintendo, and has also claimed responsibility for attacks on PBS' site where it posted an article claiming late rapper Tupac Shakur was still alive, as well as at least a half-dozen attacks on Sony.

Senate officials say LulzSec's hack did not result in any kind of data loss. "The intruder did not gain access into the Senate computer network and was only able to read and determine the directory structure of the files placed on Senate.gov," a spokesperson said in a statement released to the press.

Regardless of the outcome of the hack, the Senate still intends to review all sites hosted by the government body to ensure that they are secure.

The directory structure has been posted to the group's web site. In a statement included with the data, LulzSec said it hacked government sites because "we don't like the government very much."

In an attempt to provoke a response, the group asked "is this an act of war, gentlemen?," likely in reference to recent talk by the Pentagon that the US Government may consider cyberattacks an act of war.

Attacks by these groups have become more aggressive over recent months, as has the response from worldwide governments. In Spain and Turkey, at least 35 people suspected to be associated with the hacking group Anonymous have been detained.
