Representative Frank Wolf has said that, according to the FBI, four computers in his office have been hacked by people working from inside China. From the Los Angeles Times:
Wolf said that the computers affected in his office had been used by staff members who were working on human rights issues and that the intrusions began in 2006. Wolf said that he was planning to introduce a resolution in the House aimed at protecting congressional computers from future cyber-attacks and that he intended to speak on the House floor about the issue this afternoon.
Federal authorities have been increasingly concerned about the Chinese government deploying a diverse network of spies and scientists and others to sweep up U.S. technology in recent years.
