Rebind variant plays Jedi mind trick on home comms kit
Millions of household routers are susceptible to a flaw that creates a handy means for hackers to hijack surfing sessions or hack into home networks.
Craig Heffner, a researcher at security consultancy Seismic, is due to detail the flaw and release a proof-of-concept tool at the Black Hat conference in Vegas later this month. The DNS rebinding-related security flaw affects kit from Linksys Belkin and Dell, among others.
The sleight of hand discovered by Heffner involves establishing an attack site which runs malicious script that means a visitor’s own IP address is presented as one of the site’s alternative IP addresses, thereby granting a trusted status to a malign site. Modern browsers are designed to block earlier types of such attacks but not with this particular scenario, for reasons Heffner is due to explain at Black Hat.
The complex attack approach uncovered by Heffner involves either exploiting vulnerable routers or taking advantage of weak (default) hardware passwords, Forbes explains.
