Overview

Binary Ninja is a modern, lightweight reverse engineering platform that provides powerful analysis capabilities through its unique intermediate language (IL) system. Developed by Vector 35, it offers a scriptable interface with Python and C APIs, making it ideal for both interactive analysis and automated reverse engineering workflows.

💡 Key Strengths: SSA-based intermediate representation, live analysis, extensive Python API, cross-platform support, and active plugin ecosystem.

Intermediate Language (IL) System

IL Levels Overview

# Binary Ninja's Multi-Level IL System:

# 1. Low Level IL (LLIL) - Architecture-specific
# 2. Medium Level IL (MLIL) - Architecture-independent
# 3. High Level IL (HLIL) - C-like representation
# 4. Static Single Assignment (SSA) forms for each level

# Accessing IL in Python API:
import binaryninja as bn

# Load binary
bv = bn.open_view("/path/to/binary")

# Get function
func = bv.get_function_at(0x401000)

# Access different IL levels
llil = func.llil
mlil = func.mlil
hlil = func.hlil

# SSA forms
llil_ssa = func.llil.ssa_form
mlil_ssa = func.mlil.ssa_form
hlil_ssa = func.hlil.ssa_form

Python API and Scripting

Basic API Usage
