WASHINGTON – Four of Rep. Frank Wolf's staff computers were hacked and the Virginia Republican is blaming sources working out of China.
Wolf was bringing up a resolution on the House floor on Wednesday to let his colleagues know about the dangers of computers being open to Chinese infiltration. He was joined at a press conference by Rep. Chris Smith, R-N.J., who also says two of his computers were compromised.
The hacking is not limited to Wolf and Smith. It's believed to be widespread among a number of lawmakers from both sides of the aisle and at least one House panel — the Foreign Relations Committee. Senior congressional aides told FOX News the situation represents a "significant breach" of congressional computer security.
Congressional sources said the hacking apparently has "direct" ties back to China. Wolf is a longtime critic of the Chinese government's human rights record.
"While this has not been confirmed to me, my own suspicion is I was targeted by China because of my long history of speaking out about China’s abysmal human rights record," Wolf said.
Wolf said that in his office, the hackers "got everything," including all the casework regarding political dissidents around the world.
In comments to The Associated Press earlier in the day, Wolf suggested the problem probably goes further. "If it's been done in the House, don't you think that they're doing the same thing in the Senate?"
"I think this is very bad because you have the Chinese compromising and gaining access to computers of any number of members of the House and a major committee of the House," Wolf said. "We don't know how many others."
He also said that he detects an "apparent lack of a sense of national urgency" to address this problem within the U.S. cybersecurity community.
Similar breaches have occurred before on Capitol Hill. On Tuesday, the campaign Web site of Rep. Dennis Kucinich, D-Ohio, was hacked. It's not known if these incidents are related.
Wolf says he was told by the FBI in August 2006 that four computers in his personal office were compromised. A spokesman for Wolf said the four computers were being used by staff members working on human rights issues. The FBI did not comment on the allegations.
House Speaker Nancy Pelosi responded that the House continues to monitor attempts to access computer systems, and security officials "assured that the House has very sophisticated technology in place to prevent and detect intrusions.”
