Hackers hit the official White House Web site Monday evening, shutting it down while officials investigated the incident.
One or more attackers breached the computer system that hosts the site around 8pm Monday, a White House spokesman said. After the attempt was detected, the site was disabled until this morning, he said, calling it a "normal security response". When a breach occurs, it's a serious matter and some procedures need to be looked at, he added.
The spokesman declined to say what damage, if any, the hackers may have caused.
An investigation has begun, looking into exactly what happened and if any internal damage to the site occurred, the White House spokesman said. As for the attack possibly being linked to NATO bombings in Kosovo, the spokesman said "any and all possibilities" would be looked at.
The White House Web site includes information for the general public on past presidencies and the Clinton administration and doesn't host sensitive government data.
