F-Secure researchers have uncovered a critical vulnerability in some models of Inteno home routers that, if exploited, is severe enough to allow an attacker complete control over the victim device and the Internet traffic traveling through it. The finding highlights the security challenges plaguing consumer routers.
The vulnerability allows an attacker to install their own firmware to the device, which would still work as before, but with back doors and other unwanted features. An attacker exploiting the flaw would be able to listen in on unencrypted traffic going through the router, not just device-to-internet, but device-to-device inside the home; as well as manipulate the victim’s browsing sessions by redirecting to malicious sites.
“By changing the firmware, the attacker can change any and all rules of the router,” says Janne Kauhanen, cyber security expert at F-Secure. “Watching video content you’re storing on another computer? So is the attacker. Updating another device through the router? Hopefully it’s not vulnerable like this, or they’ll own that too. Of course, HTTPS traffic is encrypted, so the attacker won’t see that as easily. But they can still redirect all your traffic to malicious sites that enable them to drop malware on your machine.” For the full article click here
