Your mission, should you choose to accept it: Turn your router off, then turn it back on.
An analysis by Cisco's threat intelligence division, Talos, has linked the malware to the hacking group Fancy Bear. The US authorities have identified this malware as VPNFilter and, as they point out, it already affected half a million home routers worldwide and it aims to spread coordinated global attacks and record all network activities.
The FBI is recommending owners of small office and home office routers reboot the devices to temporarily disrupt the malware and aid the potential identification of infected devices linked to Russian Federation that has infected hundreds of thousands of internet routers. This malware has the ability to watch the traffic that is moving through the router - stealing data, executing commands, blocking network traffic and even "bricking" the device.
That means the malware would be able to steal logins and passwords, and monitor industrial control systems, CNET reported.
Talos, in its blog post Wednesday, said that the computer code used in the malware shows significant overlap with a malware that was responsible for multiple large-scale attacks that targeted devices in Ukraine. The simplest thing to do is reboot the device, which will temporarily disrupt the malware if it is present.
Last week, security researchers at Cisco's cyberintelligence unit Talos warned of the attack: malicious software, dubbed VPNFilter, had infected an estimated 500,000 consumer routers in 54 countries and was targeting routers from Linksys, MikroTik, Netgear and TP-Link, and possibly others.
The U.S. government says it has seized a critical web domain, called toknowall.com, which the Russian hackers were using to disseminate the malware. The install package, on the other hand, will be left intact.
Rebooting is a pretty easy process, usually requiring little more than holding down a reset button on the router, CNET explains. Also, be sure to change all default router passwords to strong passwords.
Cisco researcher Craig Williams told Reuters: "With a network like this you could do anything". Check your model's instruction manual for help with both steps.
Besides a reboot, the Federal Bureau of Investigation has stated that users should also change their login information for routers.
