Recently patched vulnerabilities provided hackers complete access to iPhones

A new report from a mobile security firm has highlighted a series of vulnerabilities in previous versions of iOS that, when used in the right context, could give an attacker complete control of a user’s device. The findings were published by Zimperium, and relate to two components in particular: the IOSurface and AppleAVE kernel extensions.

These components are responsible for driving a device’s display and allowing hardware acceleration for videos, respectively — though Zimperium has outlined eight ways in which they can be used to compromise an iPhone or iPad. The vulnerabilities concern the elevation of privileges, so unscrupulous parties can be granted free rein over the system. Once they’re in, a hacker can access a variety of personally identifiable information, like the device’s GPS location data, contacts, microphone, and even photos.

The IOSurface extension in particular has been previously linked to jailbreak methods, and with the release of iOS 10.3.2, Apple has patched the issues. However, users of older devices are still left unprotected. According to Zimperium’s Adam Donenfeld, who discovered the vulnerabilities, the exploits are so discreet that they can be performed without the user’s knowledge.

“Before the patch, the only way for a user to guard itself was to install a third-party mobile protection solution,” Donenfeld told Digital Trends. “Unless patched, without a third-party mobile protection solution there’s no way for a user to know whether he’s being attacked.”

Thankfully, Donenfeld noted that Apple has acted swiftly in issuing fixes. Zimperium notified the company of its findings toward the end of March, and Apple pushed out iOS 10.3.2 to devices in mid-May. The oldest iPhone currently supported with updates is the iPhone 5, meaning the wide majority of current iOS users have been covered. Zimperium will publish an expanded proof-of-concept explaining the vulnerabilities in greater detail soon, but the report is currently being delayed at Apple’s request.

Mobile devices carry unique risks. That’s the reason why firms like Zimperium exist — to address the concerns of smartphone and tablet users, who face a very different threat from their desktop counterparts. One of the dangers Donenfeld identifies is the behavior of many mobile devices in automatically connecting to available public Wi-Fi networks.

“Network-based threats are significant and far too easy to execute,” Donenfeld said. “Plus, malware in many forms has grown at an alarming rate in recent years. We’ve seen an increasing number of mobile vulnerabilities — such as Stagefright — being discovered.”

Despite manufacturers’ and researchers’ best efforts, Donenfeld doesn’t expect the rising tide of crime to turn anytime soon.

“Mobility provides a huge number of assets with much less risk of discovery and prosecution than traditional crimes, so it is only logical that mobile threats will continue to grow.”

This one Apple Fitness feature completely changed how I exercise

I have a confession to make: I'm not good at sticking to a workout routine. I love running, high-intensity interval training (HIIT), strength training, etc. In the moment of those exercises and in the post-workout euphoria, I feel amazing. But when it comes to waking up early in the morning to do these things before work? Well, that's where I really struggle.

This has been a problem for a while now. I go to bed with the goal of waking up early and going to the gym, but as I groggily open my eyes to snooze the alarm on my iPhone 15 Pro Max, I end up falling back asleep. And I've been repeating this over and over and over again.

Apple is about to do the unthinkable to its iPads
A person holding the iPad Air 4.

Earlier today, Apple announced that new iPads are coming this May. In my eyes, this seems to be “The Chosen One” generation. We’re likely getting an OLED display, a better keyboard (hopefully), and a chip ready to chomp the AI dinner. This gadget shall finally fill the techno-digital void in my life. At last.

Or maybe I am just trying to blindly convince myself to splurge over a thousand dollars for a machine that is “still not a Mac” and “can never be a fully fleshed out workstation.” But hey, people are spending $3,500 on a headset that gives them a headache and $700 for an AI thingamajig that can’t quite figure out what it really wants to do.
