Apple just released iOS 10.3.3 a few days ago, a system update that many have criticized for being small and unimpressive. According to Forbes, the only visible change that the update made was to add new wallpapers for the iPad Pro 12.9-inch, whose bigger display required a bit of extra attention. However, this is only the surface layer of the update, the one we can see with the naked eye.
The true heroes of the iOS 10.3.3 update are the multiple bug fixes and security enhancements that came through it for iPhones 5 and newer, fourth generation iPads and newer and sixth generation iPods. Apple released the full security log on their blog, but one of the most important fixes is detailed only at the bottom of the page. We’re talking about the critical Wi-Fi security flaw.
Not many people knew of this bug, and that includes Apple users. But apparently, the previous version of iOS left open a very wide gateway for malicious third party attackers to exploit. It seems that a hacker could take control of a device’s CPU through its Wi-Fi connection, which sounds ridiculously dangerous when considering that being connected to the Internet via Wi-Fi is more than half of our devices’ daily activity.
Apparently, these attacks profited off of a weakness in Broadcom BCM43xx products, a product family that iPhones have had since the iPhone 5. The attacks were so severe that they gained a 9.8/10 rating on the National Institute of Standards and Technology’s index. The vulnerability only appeared when users connected to open Wi-Fi networks but still, the risks of infection were pretty high. Fortunately, all that is over now thanks to the iOS 10.3.3 update.
So next time you think this new update was useless, think again.
