The FBI is urging small businesses and households to immediately reboot routers following Cisco's report that 500,000 infected devices could be destroyed with a single command.
The malware, dubbed VPNFilter, was developed by the Russian state-sponsored hacking group Sofacy, also known as Fancy Bear and APT28, according to the FBI, which last week obtained a warrant to seize a domain used to control the infected routers.
Cisco's Talos Intelligence researchers revealed in a report last week that 500,000 routers made by Linksys, MikroTik, Netgear, and TP-Link had been infected with VPNFilter.
The malware is capable of collecting traffic sent through infected routers, such as website credentials.
However, the most worrying capability is that malware allows its controllers to wipe a portion of an infected device's firmware, rendering it useless. The attackers can selectively destroy a single device or wipe all infected devices at once.
The country also blamed Russia for last June's NotPetya attacks that mostly affected Ukraine organizations but also spread within multinational corporations with offices in Ukraine.
Users with infected routers can remove the dangerous Stage 2 and Stage 3 components of VPNFilter by rebooting the device. However, Stage 1 of VPNFilter will persist after a reboot, potentially allowing the attackers to reinfect the compromised routers.
The web address the FBI seized on Wednesday, ToKnowAll[.]com, could have been used to reinstall Stage 2 and Stage 3 malware, but all traffic to this address is now being directed to a server under the FBI's control.
The FBI nonetheless is urging all small office and home router owners to reboot devices even if they were not made by one of the affected vendors. This will help neuter the threat and help the FBI identify infected devices.
The FBI recommends any owner of small office and home office routers reboot the devices to temporarily disrupt the malware and aid the potential identification of infected devices," the FBI said in a public-service announcement.
Owners are advised to consider disabling remote-management settings on devices and secure with strong passwords and encryption when enabled. Network devices should be upgraded to the latest available versions of firmware.
Cisco and the Justice Department have also urged all home and small office users to reboot routers.
The Justice Department said the FBI-controlled server to which infected devices are now communicating with will collect the IP addresses of each device.
The addresses are being shared with the non-profit cyber security group, The Shadowserver Foundation, which will disseminate the addresses to foreign CERTs and ISPs. The FBI and US DHS CERT has also notified some ISPs.
It's not known how the attackers initially infected the routers, but Symantec noted in its report on VPNFilter that many of them have known vulnerabilities.
"Most of the devices targeted are known to use default credentials and/or have known exploits, particularly for older versions. There is no indication at present that the exploit of zero-day vulnerabilities is involved in spreading the threat," wrote Symantec researchers.
Known infected devices include:
Linksys E1200
Linksys E2500
Linksys WRVS4400N
MikroTik RouterOS for Cloud Core Routers: Versions 1016, 1036, and 1072
Netgear DGN2200
Netgear R6400
Netgear R7000
Netgear R8000
Netgear WNR1000
Netgear WNR2000
QNAP TS251
QNAP TS439 Pro
Other QNAP NAS devices running QTS software
TP-Link R600VPN
I read about this and did the reboot of my router. Then I remembered that I also have another router that picks up the signal from the main router and sends it to parts of the house that aren't covered by the main router. I hadn't turned it off, so I went back and turned both of them off at the same time, so one wouldn't reinfect the other. Don't know if this makes any sense, but it seemed like a good idea.
Rebooted my router also.
Thanks, Rob

Thank you sir
Thanks Rob for the thorough update. I needed to replace an old router with a new model, and turn the power off at night, no point to leaving it on.
