blacktop/ipsw-skillSkill
Reverse-engineers Apple firmware and binaries with the ipsw CLI. Inspects IPSWs and OTAs remotely or locally; extracts kernelcaches, dyld_shared_cache, exclave, SEP, and coprocessor firmware; disassembles and cross-references DSC dylibs, KEXTs, and Mach-Os; dumps and diffs ObjC/Swift headers; decompiles and queries sandbox profiles; searches entitlements; symbolicates crashes and panics; and diffs releases. Use for iOS/macOS internals, private frameworks, kernel or firmware research, and Apple security research, even when ipsw is not named.
Why this score
Popularity score: 64/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
Security
Scanned Oct 20, 2026 at commit 1a797280aa27, with Cisco's open-source skill-scanner.
None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
