litehook

Lightweight *OS hooking library with no dependencies except for libsystem

Supported Functionality

Since this is a lightweight library, only very basic functionality is supported, this includes:

• Finding <redacted> symbols by parsing the dyld_shared_cache (litehook_find_dsc_symbol)
• Replacing a function with a branch to some other location/function, with no ability to call the original function (litehook_hook_function)
• Rebinding a symbol in the GOT of an image, similar to fishhook and dyld_dynamic_interpose (litehook_rebind_symbol)

Supported Environments:

Architectures:

• arm64e
• arm64
• armv7s
• armv7

litehook is intended to work on iOS 10 and up.
