Apple iPhone need to download this important security update

iPhone 8 users as well as any Apple owners with devices running iOS 11 need to download an important security update that has rolled out today.

The Cupertino-based tech giant have just released iOS 11.1, which brings with it one absolutely essential feature.

Apple have confirmed that iOS 11.1 fixes the KRACK attack security risk.

The vulnerability, exposed earlier this month, affects any smart device that uses Wi-Fi, cyber security experts said.

The KRACK exploit affects the WPA2 security protocol, a standard for Wi-Fi security used on almost every Wi-Fi router.

In theory it allows a hacker within range of a Wi-Fi network to read passwords, credit card numbers and photos sent over the internet.

In a post online, Apple said the fix for the KRACK attack would impact those with an iPhone 7 and later, and those with a iPad Pro 9.7-inch (early 2016 model) and beyond.

Describing how the KRACK vulnerability may work, Apple said: "An attacker in Wi-Fi range may force nonce reuse in WPA clients (Key Reinstallation Attacks – KRACK)".

Outlining how they fixed it, the iPhone maker added: "A logic issue existed in the handling of state transitions. This was addressed with improved state management."

The KRACK exploit was unearthed by researchers led by Mathy Vanhoef from the Belgian university KU Leuven earlier in October.

The experts, after discovering the exploit, carried out a “proof-of-concept” attack on an Android smartphone to learn more about the vulnerability.

Vanhoef said the attack would work against “all modern protected Wi-Fi networks” and “if your device supports Wi-Fi, it is most likely affected”.

In the paper on the Krack Attacks website, the researchers said: "All protected Wi-Fi networks use the four-way handshake to generate a fresh session key and so far this 14-year-old handshake has remained free from attack.

"Every Wi-Fi device is vulnerable to some variants of our attacks.”

The iOS 11.1 update also brings with it more than 70 new emoji for iPhone and iPad owners.

These new emoji characters including new food types, animals, mythical creatures, clothing options, more expressive smiley faces and gender-neutral characters.

The update also brings back the popular 3D Touch App Switcher gesture, which lets iOS users perform a 3D Touch gesture at the left edge of the display

By performing this gesture, it brings up the multitasking App Switcher interface.

The latest iOS 11 update, comes ahead of the worldwide release date for the iPhone X this Friday.

Pre-orders for the futuristic smartphone opened last week, but Apple have said stock will be available in-store for people without reservations on launch day.

However, if you do want an iPhone X on launch day it's best to get to one of the Apple stores which will have stock as early as possible.
