FBI Snags Top Chinese Hacker in Rare Extradition as Kash Patel Defends Controversial Italy Trip

The FBI recently secured the extradition of Xu Zewei, a Chinese national charged with orchestrating a high-profile cyberattack targeting U.S. COVID-19 research during the pandemic. This rare cross-border operation, conducted in close coordination with Italian law enforcement, marks a significant win against state-linked cyber espionage.

Xu faces federal charges related to a 2020-2021 hacking campaign aimed at American universities, immunologists, and virologists working on treatments and vaccines. Prosecutors allege Xu reported directly to China’s Ministry of State Security (MSS) and its Shanghai bureau, though many details remain classified. The indictment also connects Xu to the notorious "HAFNIUM" campaign, which exploited Microsoft Exchange Server vulnerabilities to breach thousands of organizations worldwide, including over 12,000 in the U.S.

FBI Director Kash Patel, who faced criticism for a 2026 trip to Italy that included Olympic events, insists the visit was a critical part of the effort. He told Fox News Digital that the trip helped build the necessary relationships and timing to apprehend Xu before legal hurdles could block extradition. "We created an opportunity with our partners in Italy to have him apprehended there," Patel said, pushing back on claims he was on vacation.

Patel described Xu as "one of the top two cyber criminals in the world for China," emphasizing the suspect’s role in stealing sensitive research at a time when the U.S. was vulnerable during the COVID-19 crisis. The FBI director also noted recent attempts by Chinese officials to interfere with the extradition, underscoring the geopolitical stakes.

This case fits into a broader pattern of Chinese intelligence using private contractors to mask direct involvement in cyber operations. Among the victims was a Washington, D.C.-based law firm, where hackers sought information related to U.S. policymakers.

Patel highlighted that the FBI has ramped up efforts against Chinese espionage, claiming more arrests under his watch than any previous FBI director. He warned that the MSS continues to aggressively target the U.S. for classified information and scientific research, making counterintelligence a top priority.

The Chinese embassy did not respond to requests for comment.

This extradition sends a clear message: the U.S. is intensifying its crackdown on foreign cyber threats, even as questions linger about the optics of FBI leadership’s international engagements. As the FBI pursues Xu’s co-conspirators still at large, the fight against Beijing’s espionage apparatus shows no signs of slowing.
