Router Vulnerability and the VPNFilter Botnet

10

On May 25, the FBI asked us all to reboot our routers. The story behind this request is one of sophisticated malware and unsophisticated home-network security, and it’s a harbinger of the sorts of pervasive threats — from nation-states, criminals and hackers — that we should expect in coming years.

VPNFilter is a sophisticated piece of malware that infects mostly older home and small-office routers made by Linksys, MikroTik, Netgear, QNAP and TP-Link. (For a list of specific models, click here.) It’s an impressive piece of work. It can eavesdrop on traffic passing through the router — specifically, log-in credentials and SCADA traffic, which is a networking protocol that controls power plants, chemical plants and industrial systems — attack other targets on the Internet and destructively “kill” its infected device. It is one of a very few pieces of malware that can survive a reboot, even though that’s what the FBI has requested. It has a number of other capabilities, and it can be remotely updated to provide still others. More than 500,000 routers in at least 54 countries have been infected since 2016.
