Zuk is looking for hardware exploits

Zuk Avraham, chairman and founder of Zimperium Labs, is trying to investigate a new hardware-based security vulnerability.

He is specifically trying to find the root cause of reboots on iPhones running iOS 10.3.2 and 10.3.3. Here’s what the security researcher tweeted.

Taking a look at his Twitter account, he is clearly trying to exploit a security vulnerability present in the modem chipset of iPhone.

The fact that he is specifically asking users with SIM cards to report lends even more credibility to this claim.

This issue seems to be rampant on iOS 10.3.2 and 10.3.2. A lot of users are reporting a black “loading screen” that results in a random respring or a reboot.loading screen iOS

If you ever experience the “loading screen” out of the blue, you might have this vulnerability in your iPhone modem.

Can this lead to an iOS 10.3.3 jailbreak?

Forget a jailbreak, such an exploit can lead to complete compromise of your iPhone! The general view within the Information Security community is that modem exploits are insanely powerful.

As of yet, Avraham has neither confirmed nor denied the existence of such a security vulnerability.

Since he works at a professional security company, he may or may not release this exploit for jailbreak developers.

He might even try to sell it to Apple for big bucks if it’s powerful enough.

If you happen to be running any of these firmware versions on your iPhone, kindly contact Zuk with all the necessary details.

Please do not inundate him with jailbreak requests. He has already clarified that doing so will result in a permanent block.
