iOS 12 Jailbreak: Alibaba Team Shows Off Another iOS 12.1.2 Exploit

2:30 PM

Earlier this week, we published an article about the “(Mach) post-oriented programming attack proof” series by Min(Spark) Zheng (@SparkZheng) who is an android/iOS senior security engineer at Alibaba and is also a prominent figure in the jailbreak community. At that time, there were only two posts/announcements made by Zheng via Twitter.

This time around, the third part of the series was spotted. Just like the second post, it talks about the iOS 12.1.2 which gives hope to an iOS 12 jailbreak or iOS 12.1.2 jailbreak release sometime in the future.

However, instead of the senior security engineer, it was announced via Twitter by someone who goes by the name Xiaolong Bai (@bxl1989) who is also a security engineer at Alibaba.

The (Mach) Post-oriented Programming Attack Proof Series

Before we talk about the third post, let’s first take a look at the two previous posts. As we mentioned in our previous article, these posts are probably going to form the basis of a presentation at a security conference somewhere in the world.

This is the first part of the (Mach) post-oriented programming attack proof series announced by Zheng. As you can see, it’s about a local privilege escalation for the macOS 10.14.2. Moreover, the senior security engineer also mentions @bxl1989 (or Xiaolong Bai).

For the second part of the series, it’s about an iOS 12.1.2 exploit. Aside from the iOS-powered device showing iOS 12.1.2 (Build 16C101) in operation running on an iPhone 6s, a number of command line screenshots we attached as well. With this post, it reaffirmed the hope of the jailbreak community for a future iOS 12 jailbreak release. And in this case, it’s an iOS 12.1.2 jailbreak.

Just like the previous post, the senior security engineer mentions @bxl1989. We can also see that at the moment, this second part of the series has accumulated about twice the likes and retweets compared to the previous post.

Lastly, we have the third part of the series which was posted just a few days ago. Only this time around, it was announced by Bai, another security engineer at Alibaba, crediting himself and Zheng.

Just like the previous post, it also talks about an iOS 12.1.2 exploit. However, instead of an iPhone 6s, it’s an iPhone XS Max with an A12 core. This third post also reaffirms the hope for a possible iOS 12.1.2 jailbreak release in the future.

What are your thoughts about this “(Mach) post-oriented programming attack proof” series? What are the chances of them releasing an iOS 12.1.2 jailbreak (or just iOS 12 jailbreak in general) to the public domain? Tell us in the comment section below.
