evidence: In a speech earlier this month at the University of Michigan, FBI director Christopher Wray warned of another peril, saying that the presence of TikTok software on millions of smartphones could give China "the ability to engage in malicious cyber activity." For example, intelligence agents might identify a high-value target who uses TikTok, then secretly activate their phone’s video camera or microphone to record that person’s activities. Wray also warned that TikTok could be used to conduct "influence operations" like those run by Russia in an effort to tamper with US elections. TikTok’s algorithms could be tweaked to send US viewers a steady stream of pro-Chinese news stories, or videos that disparage the United States.
