Bluetooth has quickly become the default way for devices to share data across short distances since its original invention in 1994. Unfortunately, its widespread, easy-to-use nature makes it a prime target. According to an article by ArsTechnica, researchers have created an attack that can hack a wide range of Bluetooth enabled devices running Android, Linux, and Windows. That includes billions of devices worldwide.

Called “BlueBorne”, the attack method is notably effective and far in its reach. As ArsTechnica explains, “Virtually any Android, Linux, or Windows device that hasn’t been recently patched and has Bluetooth turned on can be compromised by an attacking device within 32 feet. It doesn’t require device users to click on any links, connect to a rogue Bluetooth device, or take any other action, short of leaving Bluetooth on. The exploit process is generally very fast, requiring no more than 10 seconds to complete, and it works even when the targeted device is already connected to another Bluetooth-enabled device.”

Sounds scary, right? Well, it kind of is. Nadir Izrael, CTO and co-founder of security firm Armis, told ArsTechnica that BlueBorne “abuses the fact that when Bluetooth is on, all of these devices are always listening for connections.”

There is some good news, however, if you use Microsoft. Microsoft has patched the vulnerabilities, so recent updates should protect you against this hack. Moreover, a representative has said that the Windows Phone was never vulnerable to the attack in the first place.

Google is also working on patching the vulnerabilities for its Pixel XL and other Google-branded phones, but a total fix might take some time. Apple’s iOS prior to version 10 was quite vulnerable, but should be better going forward, and Linux is expected to release a fix soon. ArsTechnica says that the attack is most potent against Android and Linux devices.

You may not think of Nokia as a top smartphone brand, considering that in recent times it has only launched three middle-tier devices. But Nokia’s newest device releasing in September, the Nokia 8, is challenging this reputation. According to a review from The Independent, the Nokia 8 might just be worth considering as your next purchase.

“In feel alone, this is easily the best phone the new HMD Nokia has produced, slick and smooth enough to slide easily between your fingers,” said The Independent.

The Nokia 8 comes in four different shades; matte silver, polished blue, matte blue, and polished copper. It has a 5.3-inch, 2,560 x 1,440 resolution display, and with 554 pixels per inch, the sharpest resolution of any Nokia phone. Unlike the popular OLED display favoured by Samsung, the Nokia 8 keeps it simple with an LCD screen.

Cameras are undoubtedly important features on any smartphone nowadays, and the collaboration between Nokia and optical system manufacturers Zeiss should result in an excellent quality product.

According to The Independent, “The rear dual cameras are both 13-megapixel sensors, one colour and one monochrome. Huawei has a similar approach on its latest phones, saying that the monochrome sensor can get a sharper result as it grabs light quickly, and the colour one gives you the colour fidelity.” This should make photography feel a bit more professional than the average smartphone.

The Nokia 8 also boasts high-quality audio, using a system called OZO, in which three microphones work together to record better sound with no special playback system required.

The Nokia 8 will be one of the first smartphones to receive Android O when it goes live, and until then will run on the latest version available, Android 7.1.1. The functionality of the Nokia 8 will feel very similar to most Android phones, with the only stark difference being in the camera.
