How to Protect Your Home Network from VPNFilter Malware

Last week, Cisco Talos revealed a dangerous malware known as VPNFilter.

VPNFilter is a malware bug originally from Russia. It may be possible VPNFilter is connected to the Russian government. The majority of reported VPNFilter attacks are coming from Ukraine. Furthermore, this bug is not limited to Eastern Europe. VPNFilter has infected at least 500,000 devices in at least 54 countries.

This is a particularly dangerous bug. VPNFilter can delete itself and render infected routers inoperable. Additionally, VPNFilter may be used to incorporate infected routers into a botnet to be used in a Distributed-Denial-of-Service attack.

Protect Your Home Network from VPNFilter

If you own any of the routers on the above list, it is recommended you take several steps in order to ensure the safety of your home network.

  1. Update Your Router Firmware: Go to your router’s admin page and go to the Advanced or Management section to check for firmware updates. Furthermore, Open Source DD-WRT and Tomato firmware can be used to replace your router’s default buggy firmware and any other issues that may be contained within it. If the device you own is Open Source compatible, FlashRouters can upgrade the firmware for you. Find out if we support your router with our Support Plans.
  2. Perform a Factory Reset: Holding your router’s reset button for five to ten seconds will reboot the router. This will return the router to default settings and potentially clear the device of VPNFilter.
  3. Change Your Router Password: This is a simple step, but a necessary one if your device has been hacked. Changing your password will prevent access to your router from any hacker who has the previous login key.
  4. Turn off Remote Administration: Check your router’s firmware to make sure you have Remote Administration turned off. If this is on, hackers will be able to access your device more readily.

Protecting Your Network with a VPN FlashRouter

Using an Open-Source FlashRouter equipped with a Virtual Private Network is recommended for protecting your network from any outside intrusion.

A FlashRouter, like the above pictured R7000 Netgear Nighthawk DD-WRT, can be used to secure your entire home network. Moreover, it is not only the Open Source firmware that will protect your device from factory flaws.

Using a Virtual Private Network will allow you to encrypt your entire network by tunneling all of your VPNFilte rtraffic through a VPN server. Many devices, such as Smart TVs and game consoles, can only go through a VPN if they are on a VPN router. Furthermore, you will appear as if you are in the location of the VPN server according to outside traffic.

Taking advantage of a VPN router is a great first step towards building a hacker-free network.
