A Binary Ninja plugin for analyzing Swift binaries

Plugin demo movie

Description

Swift binaries contain multiple type-related metadata. This metadata is often helpful in reverse engineering. However, many disassemblers do not parse this type metadata, which poses a significant challenge when analyzing Swift binaries. This plugin solves this problem by providing the following features:

  • Parsing type metadata accessor and type metadata
  • Analyzing PWT for structs and classes
  • Identifying class methods
  • Analyzing Swift immortal and large strings
  • Visualizing protocol conformance and class inheritance

Installation

  1. Install SwiftMetadataDump
  2. Install this plugin by placing this repository's content in ~/Library/Application Support/Binary Ninja/plugins
  3. Restart Binary Ninja
