DECOUPLING: U.S. Weighs Ban on Chinese-Made Router in Millions of American Homes. “TP-Link is the bestselling router on Amazon—and has been linked to Chinese cyberattacks.”

The router-manufacturer TP-Link, established in China, has roughly 65% of the U.S. market for routers for homes and small businesses. It is also the top choice on Amazon.com, and powers internet communications for the Defense Department and other federal government agencies.

Investigators at the Commerce, Defense and Justice departments have opened their own probes into the company, and authorities could ban the sale of TP-Link routers in the U.S. next year, according to people familiar with the matter. An office of the Commerce Department has subpoenaed TP-Link, some of the people said.

Action against the company would likely fall to the incoming Trump administration, which has signaled an aggressive approach to China.

An analysis from Microsoft published in October found that a Chinese hacking entity maintains a large network of compromised network devices mostly comprising thousands of TP-Link routers. The network has been used by numerous Chinese actors to launch cyberattacks. These actors have gone after Western targets including think tanks, government organizations, nongovernment organizations and Defense Department suppliers.

Not good.
