Ipsw
ipsw is a specialized toolkit for iOS firmware analysis, binary reverse engineering, and hardware interaction. It provides a suite of tools for downloading, extracting, and analyzing firmware images and kernel caches, alongside a MachO binary analysis tool for disassembling and patching executables.
The project distinguishes itself through integrated language-model-powered code reconstruction to translate machine code into high-level source code. It also features an automation client for the App Store Connect API to manage certificates and application settings.
The framework covers a broad range of capabilities, including device management via USB and bootloader shell interfaces, firmware version comparison, and digital forensics for artifact extraction. It further supports security research through kernel cache analysis, binary entitlement querying, and the emulation of dynamic linkers.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
