Should you update your router?

I ran across the following article, “Is Your Router Vulnerable to VPNFilter Malware?“ which was a bit of an eye opener, but not exactly a surprise in the big picture. I happen to use one of the devices in question (lucky me), so I’ve been following this issue.
In mid-May, the original guidance provided by the FBI was simple: just reboot your router. “Easy enough,” I thought, and I made it happen.
Fast forward a couple of weeks and it turns out there’s a bit more to it. We now have greater understanding of the malware. It’s turning out to be more capable than initially thought, has a much more complex mitigation path, and there’s an ever-expanding list of potentially vulnerable devices.
The article provides a good overview of the impacted devices and lists the latest mitigation information. I’d summarize it as follows:
- Apply the latest firmware.
- Perform a factory reset.
- Disable remote management, if applicable.
- Change the default admin password when reconfiguring the device.
This is a great example of the shifting landscape where consumer devices are becoming more attractive targets for attack. As the steps for mitigation become more complex, it’s likely that many of the devices will remain vulnerable for the foreseeable future.
It’s something to think about as we continue to add “internet of things” devices throughout our homes.
