Hackers working for the Russian government have been using printers, video decoders, and other so-called Internet-of-things devices as a beachhead to penetrate targeted computer networks, Microsoft officials warned on Monday.

“These devices became points of ingress from which the actor established a presence on the network and continued looking for further access,” officials with the Microsoft Threat Intelligence Center wrote in a post. “Once the actor had successfully established access to the network, a simple network scan to look for other insecure devices allowed them to discover and move across the network in search of higher-privileged accounts that would grant access to higher-value data.”
