Philips Smart TVs wide open to Gmail cookie theft, other serious hacks

ReVuln

Web-connected TVs manufactured by Philips operating the most recent firmware replace are huge open to browser cookie theft and different critical assaults by hackers inside radio vary, a safety researcher has warned.

The hacks work towards Philips Sensible televisions which have a function referred to as Miracast enabled, Luigi Auriemma, a researcher with Malta-based ReVuln (Twitter deal with @revuln), informed Ars. Miracast permits TVs to behave as Wi-Fi entry factors that close by computer systems and smartphones can connect with so their display screen output may be displayed on the bigger set. The hacking vulnerability is the results of a latest firmware replace that permits anybody inside vary to hook up with the TV, so long as they know the hard-coded authentication password “Miracast.”

As soon as somebody has related to the Miracast-enabled Wi-Fi community, they will use publicly accessible software program to obtain any private information which may be contained on USB drives plugged in to the Philips Sensible TV. Extra troubling, related units can steal the extremely delicate browser cookies that many web sites depend on to authenticate customers once they entry their personal accounts.

In a video posted Wednesday, Auriemma confirmed how authentication cookies for legitimate Gmail accounts had been siphoned off a Philips TV operating the most recent firmware. The video additionally demonstrated how movies, pictures, and different knowledge saved on a USB drive related to the TV may also be accessed. The theft took seconds to hold out, and there was no seen indication to an finish consumer that something was amiss.

Along with cookie and file theft, Auriemma’s hack makes it attainable for close by attackers to hold out quite a lot of mischievous pranks. Think about the horror of an unsuspecting consumer with a lounge stuffed with friends as she discovers her TV is out of the blue and inexplicably displaying porn or different content material that not everybody in attendance considers applicable. Hackers might additionally change channels, mute or unmute the sound, or management any variety of different capabilities of the TV in actual time, with no clear indication to informal customers the way it’s occurring.

The proof-of-concept assault is the most recent to underscore the dangers of so-called Web-of-things capabilities, which remodel thermostats, LED gentle bulbs, child displays, and, sure, TVs into networked home equipment with the flexibility to ship and obtain instructions and different knowledge. Including computing and networking capabilities to on a regular basis units should not routinely be dismissed as dangerous, however customers have loads of cause to be cautious. In spite of everything, if Microsoft, Apple, and different firms with large safety groups recurrently wrestle to make their merchandise protected, what cause is there to belief firms which can be new to community safety?

Remarkably, the vulnerability within the Philips TVs was launched in a firmware model launched in December. Auriemma has since confirmed that the vulnerability exists within the present firmware, model QF2EU-0.173.46.0, when it runs on mannequin 55PFL6008S TVs. Starting with the December replace, there was no means for customers to vary the hard-coded password that close by units will need to have to entry the Miracast community. He stated he believes all 2013 Sensible TV fashions from Philips are additionally in danger as a result of they use the identical inclined firmware.

It should not be arduous for Philips to launch a brand new model that restores authentication to Miracast, and that may go an extended approach to stopping untrusted folks from accessing house owners’ units. However even then, Auriemma stated the firmware comprises what’s referred to as a listing traversal vulnerability. It is the bug that truly makes the file theft attainable, and it has been public data for no less than six months. In the meanwhile, it might make extra sense to not use Miracast in any respect.
