Unlike the writer of this article, I ordinarily do not recommend making all updates automatic unless that’s the only way they’ll ever get made. BUT this particular software update is essential for all of your Apple devices to avoid hackers.
It’s always instructive to need to make a global update. That’s when you realize — surrounded by Apple devices — how much of an Apple fan you are. (Before you ask five, and it’s that low only because I rarely keep more than one generation of anything, instead moving them to people in need.)
Here’s Why You Should Update Your iPhone Right Now (Even if You Just Did)
Hackers exploited a flaw in iOS that Apple had previously patched.
Apple prides itself on the fact that iOS is a secure mobile operating system. It’s certainly not perfect, but considering the company recently offered $1 million to anyone who can hack it, it must feel pretty good. That’s why it’s such a surprise the company managed to reopen a flaw it previously patched, and it affects everyone who was running the most recent version of iOS.
This afternoon, the company released an emergency update (iOS 12.4.1) to fix a major problem–one the company itself created. The update is available as an over-the-air update to anyone with an iPhone 5 or later, or iPad Air or later. If you’re running iOS 12.4, you should update your device immediately.
While Apple itself doesn’t provide much information about the flaw, the company did make a point of recognizing Ned Williamson from Google Project Zero as having reported the vulnerability, along with the hacker and “researcher” @Pwn20wnd, who created the jailbreak.
Jailbreaking was common early in the days of the iPhone when users wanted access to apps unavailable through the App Store, or to install profiles that allowed for other functionality (like unlimited data, back in the day). Now, however, it’s far more difficult to jailbreak iOS, though that doesn’t mean hackers aren’t constantly trying. In fact, iOS 12.3 had patched this very flaw until Apple inadvertently reopened the door to hackers with 12.4.
This specific flaw could result in a hacker taking over your device through a malicious webpage coupled with a browser exploit. It’s not clear whether any examples of this happening exist in the wild, but as with any hack, it’s only a matter of time.
I imagine Apple never intended to update iOS 12 beyond 12.4, with iOS 13 just around the corner, but the last thing the company wants is for large numbers of devices to be compromised right before it releases new iPhones next month.
Of course, if you’re a hacker, maybe you’d rather be able to jailbreak your device and take your chances. In that case, definitely don’t update your iPhone. For the rest of you who would rather keep your personal information and iOS device secure, updating is simple. Just open your Settings app, go to General > Software Update and tap “Download and Install.” That will download the current version and update it on your device.
While you’re at it, you might want to go ahead and tap on “Automatic Updates,” and turn them on to be sure your device is always kept up to date.
