Some of these attacks weaponized then zero-days in Microsoft Exchange Server, a threat activity cluster that Microsoft tracked as Hafnium, to breach targets and deploy web shells for remote administration.\\n\\nXu worked for a company named Shanghai Powerock Network Co. Ltd. when the attacks were carried out, per the indictment. The U.S. Department of Justice (DoJ) said Powerock was one of many \\”enabling\\” companies in China that conducted hacking operations for the government.\\n\\n\\”In early 2020, Xu and his co-conspirators hacked and otherwise targeted U.S.-based universities, immunologists, and virologists conducting research into COVID\u201119 vaccines, treatment, and testing,\\” the DoJ added. \\”The charges further allege that beginning in late 2020, Xu and his co-conspirators exploited certain vulnerabilities in Microsoft Exchange Server, a widely-used Microsoft product for sending, receiving, and storing email messages.\\”\\n\\nHowever, the defendant has repeatedly denied any involvement in Chinese government hacking operations, claiming his arrest was a case of mistaken identity. He was in Milan with his wife on vacation when he was apprehended. Speaking to TechCrunch, Xu’s lawyer said he pleaded not guilty to all charges during a court hearing on Monday. Zhang Yu remains at large.\\n\\nFound this article interesting?
