Sounds cool and convenient, right? But as people left the festival others were lined up at the exit, eager to buy their wristbands. Simply holding their wristbands up to the vendor’s reader was enough to pay for drinks, food and merchandising. For example, this year, some music festivals allowed participants to load their wristband pass with credit card information, thus avoiding the need to carry a bag or wallet, or to have to dig around for change in the middle of a busy crowd. However, wearables are an area for concern - it’s the information that they hold that can be valuable. As Gary Davis of Intel says, the real weak link is the user’s mobile phone: most wearables link to phones, which by comparison hold vastly more personal data and exhibit many of the same vulnerabilities. That being said, HP has found some major areas for concern in many smart watches, including insufficiently robust authentication, vulnerability to man-in-the-middle attacks, and poor firmware updates. Again, the majority simply do not connect directly to the Internet. Therefore, hacking a pacemaker or similar device is highly unlikely at present.Īnother IoT fable, at least for the time being, concerns smart watches. Most medical appliances are too small to allow integration of a mobile phone connection and, in any case, consumer concerns over placing phone transmitters in the body restrict the development of the technology. Most personal devices aren’t connected to the Internet at all they use Bluetooth to connect to other smart devices. Security myths around connected devices are also plentiful. Think of it like leaving the window open in your spare room there may not be anything of value in the room itself but it allows access to the rest of your home unless properly secured. IoT devices, however innocuous they may seem should be thought of as a point of entry. A similar weakness has been identified in smart light bulbs, when hackers were able to obtain the passwords for the connecting Wi-Fi network as they were passed from one bulb to another. The thought of a hacker gaining control of your refrigerator may be less daunting than them taking control of your steering wheel on the motorway, but these products can act as a gateway to much more sensitive information.Īn example of such a hack was the recently exposed man-in-the-middle vulnerability of a Samsung smart refrigerator: its calendar integration functionality provided hackers with access to the owner’s network and the ability to steal linked Gmail login credentials. Hacked vehicles are an obvious cause for concern, but the hazards presented by apparently innocuous devices such as the "smart fridge" or "connected toaster" also warrant equal consideration. Tesla quickly developed a fix, which has been sent to all of the affected vehicles. Although it took closer to a year to pull this hack off, the researchers were able to apply the hand brake, lock and unlock the car, and control the touch screen displays. The two described the hack as "fairly easy" and "a weekend project".Ī few months later, news broke that researchers had hacked a Tesla Model S, once again via the car’s entertainment system. Hacking into the Jeep’s electronics through the entertainment system, they were able to change the vehicle’s speed, alter its braking capability, and manipulate the radio and windscreen wipers. In April, Cybersecurity experts Charlie Miller and Chris Valasek revealed a software flaw that allowed them to take control of a Jeep Cherokee on the move - all from a laptop computer at home. However, with poor Internet security expertise some manufacturers are being caught out. Cars, for instance, have only recently become connected, although they have long been computerized. With so many connected devices we decided to take a look at those that have made the headlines so far this year. The Internet of Things (IoT) isn’t a new concept, but it has gained momentum especially within the last year, as more and more connected devices have come to market. While connecting everything brings added convenience to our everyday lives, it’s crucial to understand what we may be compromising from a security perspective, and importantly, which devices could pose a threat either now or in the future.
