There is growing concern about a Russian cyberattack that is targeting the consumer and small business internet routers.
The malware attack called "VPNFilter" has been happening since 2016, but hackers have stepped up the attack in recent weeks to the point it's prompted the FBI to issue guidance to all router owners.
What do they want you to do?
Switch your router off and on again, basically.
The hack happens in three stages, the first stage being the malware establishing itself as a presence in your router.
The second collect files stored on your router (your personal data) and even has the capability of destroying the router completely, while the third stage can spy on the traffic routed through your device (including your website passwords).
If you switch your router off and on again, it should stop Stage 1 from becoming Stages 2 and 3 at least for the time being and give the FBI more time to figure out which routers are already infected.

And if you find your router is already infected with Stage 1, Symantec advises you carry out a "hard reset" of your device by holding down the small reset switch that should be on your router for 5-10 seconds.
This wipes any configurations or passwords you have stored on the router, so you'll need to re-enter these upon reboot.
Which routers are affected?
The FBI says all internet users should reboot their routers by switching off and on, but the Cisco blog post says more than 500,000 routers have already been infected across 54 countries.
Even though rebooting your router temporarily stops Stages 2 and 3, it doesn't wipe Stage 1 from your device, which is why a hard factory reset is needed as well as installing the latest patches from the maker of your router.
While it's hard to figure out if your router has been infected with Stage 1, the owners of the following devices should carry out a hard factory reset as soon as possible:
