About This Tool

Hexrays Toolbox - Find code patterns within the Hexrays ctree

Primary Use Case

This tool is primarily used by reverse engineers and security researchers who work with Hex-Rays decompiler to identify and analyze code patterns in decompiled binaries. It helps automate the detection of vulnerabilities or interesting code constructs by querying the Hex-Rays ctree representation, improving efficiency during binary analysis.

Key Features

Pattern matching within Hex-Rays ctree structures
Integration with Hex-Rays decompiler
Facilitates vulnerability scanning in decompiled code
Supports complex code pattern queries
Enhances exploitation research by identifying exploitable code patterns

Insights & Recommendations

Requires Hex-Rays decompiler plugin for IDA Pro to function. Users should be familiar with Hex-Rays ctree structures and IDA scripting to effectively utilize this tool.

Installation

Clone the repository: git clone https://github.com/patois/HexraysToolbox.git
Open IDA Pro with Hex-Rays decompiler installed
Place HexraysToolbox scripts in the IDA plugins or scripts directory
Load the toolbox within IDA to access its functionality

Usage

ht.search(pattern)

Searches the Hex-Rays ctree for the specified code pattern.

ht.find_all(pattern)

Finds all occurrences of a given pattern within the decompiled code.

ht.highlight(node)

Highlights a matched node in the Hex-Rays decompiler view.

Smart Usage Notes

Integrate HexraysToolbox with automated exploit frameworks like Metasploit to streamline vulnerability exploitation workflows.Use pattern matching queries to build a knowledge base of common vulnerable code constructs for faster triage.Incorporate HexraysToolbox into reverse engineering pipelines to accelerate malware analysis and threat hunting.Leverage the tool to create custom detection signatures for blue teams based on discovered vulnerable code patterns.Deploy in purple team exercises to bridge gap between offensive discovery and defensive detection capabilities.
