The US Rewards for Justice (RFJ) programme is seeking information on Chinese hacker Zhang Yu under a reward offer of up to $10 million (£7,565,150) over alleged theft of COVID-19 research at American institutions beginning in early 2020.
Zhang remains at large, according to RFJ. His alleged partner, Xu Zewei, was extradited to the United States in April 2026 after his arrest by Italian law enforcement, following alleged intrusions targeting researchers and computers running Microsoft Exchange Server.
