Silk Typhoon Operator Xu Zewei Extradited to US — First MSS Shanghai Bureau Hacker Held Accountable

Xu Zewei, a hacker attributed to the MSS Shanghai Bureau and the Silk Typhoon (formerly Hafnium) APT group, has been extradited from Italy to face US federal charges relating to the theft of COVID-19 vaccine research, defence contractor IP, and financial sector data via Exchange Server zero-days. The extradition marks the first successful prosecution of a Silk Typhoon operator and sends a direct signal to MSS-affiliated cyber operators.
