Chinese hacked Over Four million federal workers information

These guys are smart, nobody seem to be safe when it comes to Internet.

Chinese hackers are believed to have broken into US government computer networks to steal the sensitive details of four million federal workers.

The Department of Homeland Security admitted the 'shocking' breach yesterday with one security expert calling it an 'attack against the nation'.

It is now feared the stolen data could be used to blackmail, defraud or impersonate federal employees - and the FBI has launched an investigation.
