U.S. counterintelligence officials say Silicon Valley is facing a new kind of espionage threat — one that blends old-fashioned seduction with modern tech infiltration.
According to intelligence experts, Chinese and Russian operatives have been targeting American engineers, executives, and startup founders through what some are calling “sex warfare” — a strategy that uses personal and romantic entanglements to extract trade secrets and technological data.
James Mulvenon, chief intelligence officer at Pamir Consulting, said the tactic has grown more aggressive in recent months. “I’m getting an enormous number of very sophisticated LinkedIn requests from the same type of attractive young Chinese woman,” he told The Times. “It really seems to have ramped up recently.”
Mulvenon, who has studied espionage for three decades, said the U.S. is particularly vulnerable because “we, by statute and by culture, do not do that. So they have an asymmetric advantage when it comes to sex warfare.”
But the seduction angle is just one part of a much larger effort. U.S. counterintelligence officials say foreign governments — particularly China’s Communist Party — are deploying investors, academics, and even crypto analysts to collect sensitive information. “We’re not chasing a KGB agent in a smoky guesthouse in Germany anymore,” one senior official said. “Our adversaries are using a whole-of-society approach.”
A former intelligence operative told reporters about a case involving a Russian woman who married an American aerospace engineer, only to later emerge as a cryptocurrency expert with ties to Russian soft-power programs. “Showing up, marrying a target, having kids — and conducting a lifelong collection operation,” he said. “It’s uncomfortable to think about, but it’s prevalent.”
The financial stakes are enormous. Intellectual property theft costs the U.S. economy an estimated $600 billion annually, with China identified as the leading culprit. In one recent case, a Chinese national tried to sell Tesla trade secrets to undercover agents for $15 million. He was sentenced to two years in prison last December.
Meanwhile, the Chinese government has turned “innovation competitions” into another espionage tool. American startups are invited to pitch their ideas to Chinese investors, only to be required later to move their operations — and their intellectual property — to China in exchange for funding.
One biotech CEO described being followed by officials and forced to wear a microphone during one such competition. “They would record everything I’d say, then ask detailed questions about how we do it,” he said. “It felt like surveillance disguised as business.”
Experts warn that the U.S. has yet to mount a coordinated defense against these tactics. “The Chinese understand our system and know how to exploit it,” said Jeff Stoff, a former national security analyst. “Right now, we’re playing catch-up in a war that’s already well underway.”
