U.S. House spokesman Jeff Ventura in the chief administrative office said hackers attacked 49 sites that are managed by a third-party vendor on Wednesday night. Here is the story.
Ventura did not say if authorities had identified any suspects or who the third-party vendor was. But this is not the first time government sites' are attacked.
Chinese hackers have been suspected of penetrating White House sites several times, the Financial Times has reported. North Korean hackers have been suspected of hacking U.S. military secrets via a Chinese IP location, the Associated Press has reported.
