![]() government issued a warning about it Friday (Dec. After giving Netgear more than three months to respond, Acew0rm went public with his concerns on Twitter and YouTube late last week. He says he contacted the company, which did not reply to his concerns. Louis-based security researcher who used the name Acew0rm, found a huge flaw in two high-end Netgear routers. The information on the vulnerability comes from a variety of sources, but here’s the rough chronology. Who found this attack, and what is Netgear doing about it? UPDATE: Netgear has added beta firmware for the R6250 (opens in new tab), R6700 (opens in new tab), R6900 (opens in new tab), R7100LG (opens in new tab), R7300DST (opens in new tab), R7900 (opens in new tab), D6220 (opens in new tab) and D6400 (opens in new tab). A Netgear security advisory (opens in new tab) states that a permanent solution is being worked on for these models and all other affected models. UPDATE: Netgear has created temporary firmware that fixes the problem for the R6400 (opens in new tab), R7000 (opens in new tab) and R8000 (opens in new tab). There’s no evidence that attackers have exploited this vulnerability in the wild, but as it’s been out for four days, and it’s so easy to do, the floodgates are open. In theory, this fix should not affect your router’s ability to provide internet service, making it a smart, if imperfect, fix for the time being.Īlternatively, if you have an older router in the closet, now might be the time to pull it out and put it to work. On the other hand, neither will an attacker. This means you won’t be able to access any of your router’s administrative functions - like changing passwords, or opening ports - until you physically reboot the router. Into your Web browser, and the command will disable Netgear’s RouterLogin administrative software. Ironically, you can do this by taking advantage of the same exploit that allows infiltration in the first place. Changing your IP address will prevent random strangers from finding you online, but won’t prevent an infiltration if someone targets you specifically and discovers it, or if someone can get onto your local network, which by default discloses your router's IP address.Ī more complete, but temporary, workaround is to disable the router’s administration web interface completely. Netgear provides instructions (opens in new tab), although only the tech-savvy among you will want to try this it’s a bit of a process. First, you can change your router’s local IP address. There are two workarounds, although the first is not entirely effective. (You can use commands other than reboot, if you like, but that’s a fairly harmless one.) How to temporarily shield your Netgear router from attack If the router reboots, your model is vulnerable to remote infiltration, and you should unplug it until Netgear provides a fix. Which does NOT require that you know your router's local IP address. ![]() (Here's how to find your home router's local IP address.) Many routers will respond to the even simpler substituting your own router's local IP address for the term set off by brackets. While you're at home and connected to the local network, simply go to an Internet browser and type the following command: Luckily, there is a very simple test you can perform to see if your model is vulnerable. How to tell if your Netgear router is vulnerable UPDATE: Netgear has added the Nighthawk AC1900 Smart WiFi Router (R6900), AC1200 WiFi VDSL/ADSL Modem Router (D6220) and AC1600 WiFi VDSL/ADSL Modem Router (D6400) models to the list of affected routers. UPDATE: Netgear has added the AC1600 Smart WiFi Router (R6250), Nighthawk AC1750 Smart WiFi Router (R6700), Nighthawk AC1900 LTE Modem Router (R7100LG), Nighthawk DST 1900 Dual-Band WiFi Router (R7300DST) and Nighthawk AC3000 X6 Tri-Band WiFi Router (R7900) to the list of possibly affected routers. Since many Netgear routers run on similar firmware, the vulnerability could be more widespread than the researchers and Redditors anticipated.
