Hackers hit US Senate

The US Senate is reviewing the security of all its websites after admitting to being hacked.

According to the Senate, no individual senator's information had been compromised, but officials were looking into claims made by hacker group Lulz Security, which said it had posted proof on its website.

“We don't like the US government very much,” the hackers posted. “Their boats are weak, and their sites aren't very secure. In an attempt to help them fix their issues, we've decided to donate additional lulz in the form of owning them some more!"

The hackers posted a list of directories as proof of their exploits, forcing Senate officials to admit the breach and rethink their security.

Despite the attack, the Sergeant at Arms Office, which provides security for the Senate, said no serious damage had been done.

"We were responding to their allegations. Basically what we're saying that the server they got into is for public access and is in the public side," Senate official Martina Bradford told the Reuters news agency.

"Although this intrusion is inconvenient, it does not compromise the security of the Senate's network, its members or staff. Specifically, there is no individual user account information on the server supporting senate.gov that could have been compromised."

Lulz Security, which has hacked into Sony's website and the British NHS in recent weeks, went on to mock the US officials' stance that it would respond to cyberattacks from foreign countries with traditional military force.

“Is this an act of war, gentlemen?” the group said. “Problem?”

The group also claimed to have breached the network at gaming company Bethesda.
