New Attack on Home Routers

August 10, 2021

We live in strange times. Cyber attacks occur on a daily basis and addressing them should now be part of any technology implementation. That even includes IoT devices such as your video doorbell or smart (are they really smart?) lightbulbs. Malwarebytes has a post warning that home routers are now being attacked just days after the announcement of a recent vulnerability. The tactic of the cyber criminal is to attack any vulnerability very quickly after being announced. The goal is to compromise a device before the end-user applies the patch. Just two days after Tenable announced the firmware vulnerability, Juniper Threat Labs started seeing attacks. Yet again, another reason to apply any updates as soon as they are available.

The vulnerable router firmware is found in products made by SonicWall, D-Link, Netgear, Cisco, Tenda, MicroFocus, and Netis. Tenable published a list of approximately 36 impacted devices along with the vulnerable firmware version. Contact the manufacturer of your device for any updated firmware that may be available. Tenable published the technical “propeller head” details if you are interested in how the authentication bypass works.
