VPNFilter and The Importance of The Home Network


Since May of 2018, we’ve heard a lot about VPNFilter malware and the growing number of affected devices. We’ve even been given the directive to reboot our routers to stop the malware which also enables the FBI and other security groups to better track it. While rebooting the router won’t remove the malware, it will stop the advanced portions of VPNFilter from continuing. To remove the Stage 1 VPNFilter payload, you must apply the proper patch and updates from the manufacturer.

Originally it was thought that the VPNFilter malware was only affecting a few older routers and firmware. However, as the days continued, it has been revealed that numerous small office and home routers have also been affected. The reach of this malware into consumer homes brings up a very important point. When thinking about cybersecurity, most people would naturally think of corporate networks and data breaches. And who would blame them? We rarely think to look at the equipment in our own homes that provides us with connectivity. This case proves how dangerous that can be. VPNFilter can not only render a router or NAS device inoperable, but it can also provide a man-in-the-middle attack. As we’ve examined before, this type of attack allows passwords and other confidential information to be captured from the SSL traffic that crosses it.

As our homes become increasingly filled and connected with Internet of Things (IoT) devices, or
Smart Home devices as they’re commercially known, it becomes that much more important to address the security of the equipment outside our offices. We need to make sure that our router’s firmware stays up-to-date and look into replacing the hardware regularly. These devices are our first line of defense when we leave our corporate controlled networks and are becoming just as important.
