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.

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.
