The routers—mainly Cisco and Netgear devices that had reached their end of life—were infected with what’s known as KV Botnet malware, Justice Department officials said.

From there, the campaign operators connected to the networks of US critical infrastructure organizations to establish posts that could be used in future cyberattacks.

Before the takedown could be conducted legally, FBI agents had to receive authority—technically for what’s called a seizure of infected routers or "target devices"—from a federal judge.

"To effect these seizures, the FBI will issue a command to each Target Device to stop it from running the KV Botnet VPN process," an agency special agent wrote in an affidavit dated January 9.

Wednesday’s Justice Department statement said authorities had followed through on the takedown, which disinfected "hundreds" of infected routers and removed them from the botnet.

To effect these seizures, the FBI will issue a command to each Target Device to stop it from running the KV Botnet VPN process.
