If you have a wireless Internet router in your home, you need to turn it off and turn it back on as soon as possible.
The FBI is urging all households and businesses to do the simple reboot to avoid being compromised by Russian-linked cyber attackers. The attackers are using VPNFilter Malware to gain access to consumer routers and making them inoperable. A public service announcement from the FBI warns, "The malware can potentially also collect information passing through the router. Detection and analysis of the malware’s network activity is complicated by its use of encryption and misattributable networks."
The VPNFilter malware can effect routers made by Linksys, Mikrotik and Netgear. The fix is as easy as turning it off and back on. If that doesn't work, it should be reset and wiped clean.
Seems like some pretty high tech crazy stuff. For more on this go HERE!
Truthfully, it's probably a good idea to do this frequently. Maybe even change your WiFi password from time to time.
