The U.S. government in recent months launched an operation to fight a pervasive Chinese hacking operation that successfully compromised thousands of internet-connected devices, according to two Western security officials and one person familiar with the matter.

The Justice Department and Federal Bureau of Investigation sought and received legal authorization to remotely disable aspects of the Chinese hacking campaign, the sources told Reuters.

The administration of U.S. President Joe Biden has increasingly focused on hacking, not only for fear nation states may try to disrupt the U.S. election in November, but because ransomware wreaked havoc on corporate America in 2023.
