In reality the syntax of NSPredicate is a full scripting language. It involved NSPredicate, an innocent looking class that allows developers to filter lists of arbitrary objects. While much attention was given to the first exploit, we were much more interested in the second as it described a way to dynamically execute arbitrary code in another process which completely sidestepped code signing.

Part 1 described the initial exploitation of PDF parsing code and Part 2 laid out the sandbox escape. They further collaborated with Google Project Zero to analyze the exploits, leading to a pair of posts detailing the methods used in the attack. In September 2021 Citizen Lab revealed FORCEDENTRY, a 0-click iOS remote code execution exploit that targeted a Saudi activist in order to infect their iPhone with the Pegasus Malware. These issues could be used by malicious applications and exploits to gain access to sensitive information such as a user's messages, location data, call history, and photos. The vulnerabilities range from medium to high severity with CVSS scores between 5.1 and 7.1. The Trellix Advanced Research Center vulnerability team has discovered a large new class of bugs that allow bypassing code signing to execute arbitrary code in the context of several platform applications, leading to escalation of privileges and sandbox escape on both macOS and iOS. As macOS has continually adopted more features of iOS it has also come to enforce code signing more strictly. The ability to dynamically execute code was nearly completely removed, creating a powerful barrier for exploits which would need to find a way around these mitigations to run a malicious program. Only applications that were cryptographically signed by a developer certificate trusted by Apple could be executed, and scripting languages like AppleScript were not found on iOS. Since the first version of iOS on the original iPhone, Apple has enforced careful restrictions on the software that can run on their mobile devices.
