Security researchers have discovered surveillance implants in routers made in China that are sold globally. The implants are backdoor-like and are hidden in the firmware of the routers. Three different types of these implants were found. The discovery was made by security researchers, although the specific details of the researchers and the affected routers are not provided. The implants suggest a potential security risk for users of these routers.
