Could your smart TV be HACKED? 'Red button' feature could be used to hijack web accounts

  • Researchers at Columbia University claim smart TVs can be hacked
  • So-called hybrid TVs can be hijacked using a $250 (£150) 1-watt transmitter
  • The scientists are set to discuss the exploit in a paper later this year
  • They claim attackers could get access to viewers' internet accounts
  • They could then post on Facebook, write fake reviews, and much more

By Jonathan O'Callaghan

A team of scientists at Columbia University claim hybrid smart TVs that blur the line between televisions and the internet are vulnerable to a simple hack.

Coined the ‘red-button attack’ - named after the red button used on modern smart TV remotes to access additional content - the flaw can be exploited with just a $250 (£150) transmitter.

In just minutes, someone using a smart TV could find their various internet accounts sending spam, printing coupons and writing fake reviews without their knowledge.

Hackers could, in theory, also use these accounts to harvest personal information.

Yossi Oren and Angelos Keromytis from the Network Security Lab have outlined their research in a paper set to be released later this year.

The hack is apparently remarkably easy to perform.

HOW DRONES CAN ALSO STEAL YOUR IDENTITY

Experts in London recently proved it's possible to use drones to steal data.

They modified an aircraft capable of tapping into a phone's Wi-Fi settings.

Once it had access, it was able to read and steal personal information.

Called Snoopy, the drone takes advantage of smartphones that actively search for networks.

From this it can also see networks those devices have accessed in the past.

During tests, hackers exposed credit card information and passwords.

According to Forbes, it would occur while someone is watching TV and would be over in just 12 minutes.

 

The attack works by exploiting a vulnerability in Hybrid Broadcast-Broadband Television (HbbTV).

This ‘allows broadcast streams to include embedded HTML content which is rendered by the television,’ the researchers wrote in their paper.

‘This system is already in very wide deployment in Europe, and has recently been adopted as part of the American digital television standard.’

The hacker would then, in essence, take over the channel a viewer was watching for a short amount of time.

This would be done by using a simple amplifier, costing as little as £150 ($250) on a rooftop to hijack networks across an area of 0.5 square miles (1.4 square kilometres).

Alternatively, a transmitter could also be placed on a drone, which could hover outside the windows of houses to hijack TVs.

In doing so, the hacker would have access to any websites the viewer was logged into on their smart TV.

This could range from getting access to their Facebook accounts to writing fake reviews on websites for products.

The attack could be carried out by attaching a small and cheap transmitter to a drone (stock image shown) and then hovering outside a victim's window. The attackers could also set up a transmitter on a roof to potentially hijack tens of thousands of TVs across an entire city

HbbTVs broadcasts can be hijacked because they are not linked to a web server, which also makes attacks virtually untraceable.

‘This enables a large-scale exploitation technique with a localised geographical footprint based on radio frequency (RF) injection,’ the researchers continue.

This ‘requires a minimal budget and infrastructure and is remarkably difficult to detect.’

‘In a dense urban area, an attacker with a budget of about $450 (£270) can target more than 20,000 devices in a single attack.’

There are a number of possible solutions. The most drastic includes cutting all internet access to smart TVs.

Alternatively, broadcasters could begin to integrate smart TVs into a network that could see if they are being hijacked by monitoring for high spikes in signal strength.

Perhaps the most simple solution, though, would be to have a confirmation box pop-up on screen when a viewer’s smart TV is trying to open an app such as Facebook.

This, however, would detract from the current seamless and smooth integration between TV and internet favoured by companies at the moment.

WHY THE RISE IN 'SMART' DEVICES MIGHT BE A PROBLEM

'This potential attack method isn't related specifically to the use of the red button on a TV remote specifically, but to any interaction with a smart TV,' says David Emm, senior security researcher at Kaspersky Lab in Russia.

'Such an attack would effectively be a "man in the middle" attack, with hackers placing themselves between the consumer and the broadcaster and injecting their own, bogus information into the broadcast stream - for example, fake adverts and other content.

'After hacking the radio signal, hackers "become the broadcaster" and even have the ability to hack into anything sent or received by the consumer.

'One problem with such an attack is that, since it would involve hacking into the radio signal through the use of an antenna, it would be difficult to track down the attackers.

'It’s reminiscent of someone sniffing the traffic on a public Wi-Fi hotspot or setting up a fake one.

'Providers need to ensure they are considering such security implications of new technology.

'When new technologies emerge, the focus tends to be on the positive benefits - how the technology will make people's lives easier - not enough focus is placed on the risks inherent in the use of the latest technology.

'Smart fridges, garage doors, car entertainment systems and electricity meters are all examples of new technology that all benefit from Internet connectivity, but the extension of technology in this way also brings the possibility of more cyber-attacks.'

"My" LG was smart until it was found that LG were using these devices to snoop. It's now just a large dumb screen with a sometimes wired connection. Be smart and buy dumb, control the stuff you own.

Let me guess, we'll need special TV antivirus software and a firewall. Yours for only £40.

With all the other gadget people have in their homes, I really cant see the point of Smart TV's!

I wouldn't use a smart TV for anything other than YouTube and catch up TV. If you want easy access to the internet buy a tablet or smartphone.

Nothing is safe anymore. Last week I bought a new pack of jockey under ware and when I put on the first pair I swore I felt a distinct humming in the material of the crotch. I looked up and I'll be damned if there wasn't a drone flying over my house at that very moment. I just scratched my head and wondered what information the government got from that?

Err... not if you don't use it for the internet. It really is quite sad how some people are so obsessed with the latest gadget.

Fortunately i'm not sad enough to need crackbook on my TV so I chose a TV without the smart features.
