Days after three men were arrested in connection with the Anonymous hacking ring US officials have announced that hackers managed to break into the Senate website at the weekend.

This is the latest in a long line of high profile cyber attacks, although an official said whilst the attack had been 'inconvenient' the security of the staff had not been compromised.

Lulz Security, a loosely aligned group of hackers, claimed it had carried out the attack for fun.

Sony, Nintendo and Fox News have all been targeted by Lulz in recent months as the number of hacks increases rapidly.

Martina Bradford, Senate Deputy Sergeant-at-Arms, confirmed the breach of security had been noticed at the weekend and since then all sites hosted on were being reviewed.

"Specifically, there is no individual user account information on the server supporting that could have been compromised," she said in a statement.

Files from the Senate website were posted online by Lulz Security to prove they had carried out the attack, although none were of a sensitive nature.

"We don't like the US government very much," Lulz Security said at the top of a release.

"This is a small, just-for-kicks release of some internal data from - is this an act of war, gentlemen? Problem?" it added.

The last comment comes on the back of the US recently saying that they would consider cyber attacks as 'acts of war'.
