evidence: FBI Director Christopher Wray warned about the growing threat of Chinese cyberattacks against U.S. electrical grids and other infrastructure in an appearance Wednesday morning before the House Select Committee on the Chinese Communist Party. "China’s hackers are positioning on American infrastructure in preparation to wreak havoc and cause real-world harm to American citizens and communities, if or when China decides the time has come to strike," said excerpts of Wray's prepared testimony released by the FBI. [...] Wray’s remarks add to a series of stark warnings he has issued about the Chinese government’s hacking capabilities. In an interview with NBC News in 2022, Wray said that he was shocked to learn the scale of Chinese efforts to steal U.S. technology when he became FBI director in 2017 and that the FBI had launched an average of two counterintelligence investigations a day to counter those threats.
