Hex Rays

2014 Plug-In Contest


Hex-Rays Plugin Contest Results 2014

We’ve had four contestants this year. All of them were interesting, but we had to choose three. Here’s the final ranking:

 

 

Congratulations to the winners!

Below is the full list of submissions:


  • Bignum dumper by Milan Bohacek, Charles University in PragueLast year’s winner is back with a new plugin. His description:

    Bignum dumper

    Is an IDA plugin with dual purpose.

    • Assisting with dumping of big integers from IDA database.
    • Find relations between the acquired integers.

    Our comments:

    This plugin is very useful when working with crypto code which uses big numbers, such as RSA or ECC. It knows many common formats of storing such numbers and even has some heuristics to detect them automatically.

  • BinSourcerer from Concordia UniversityAshkan Rahimian from Concordia University sent an interesting submission:

    BinSourcerer is an assembly to source code matching framework written in Python. The main purpose of BinSourcerer is to recreate the functionalities that RE-Google provided, until the Google Code Search API was discontinued. This plugin can be used for code search (GitHub, Ohloh, etc.) and function tagging. It generates a disassembly feature file that can be used in various binary analyzes. Moreover, the framework functionalities are easily expandable.

    Our comments: In addition to code search, the plugin can tag the functions in the binary based on the APIs being used. This can save time when dealing with many different samples. The author also provided several videos demonstrating the features of their plugin.

  • GraphSlick from MicrosoftElias Bachaalany, Ali Rahbar and Ali Pezeshk from Microsoft submitted a plugin which solves a very interesting problem: automated detection of inlined functions. It highlights similar groups of nodes and allows you to group them, simplifying complex functions. The authors provide an accompanying presentation which explains the algorithms behind the plugin and shows sample use cases.

  • IDA Sploiter, IDA Patcher, and IDA Pomidor by Peter KacherginskyPeter has submitted not one or two, but three plugins! He provided the following descriptions:

    IDA Sploiter

    IDA Sploiter is a plugin for Hex-Rays IDA Pro disassembler designed to enhance IDA’s capabilities as an exploit development and vulnerability research tool. Some of the plugin’s features include a powerful ROP gadgets search engine, semantic gadget analysis and filtering, interactive ROP chain builder, stack pivot analysis, writable function pointer search, cyclic memory pattern generation and offset analysis, detection of bad characters and memory holes, and many others.

    This plugin brings vulnerability research functionality from various debuggers and scripts under a single, powerful and convenient platform.

    IDA Patcher

    IDA Patcher is a plugin for Hex-Ray’s IDA Pro disassembler designed to enhance IDA’s ability to patch binary files and memory. The plugin is useful for tasks related to malware analysis, exploit development as well as bug patching. IDA Patcher blends into the standard IDA user interface through the addition of a subview and several menu items.

    This plugin exposes many of IDA’s internal patch management features using various UI elements.

    IDA Pomidor

    IDA Pomidor is a fun and simple plugin for the Hex-Ray’s IDA Pro disassembler that will help you retain concentration and productivity during long reversing sessions. The plugin uses a Pomodoro Technique©, a popular time management technique.

    This plugin helped me survive through long reversing sessions and I hope you will find it useful as well.

    Our comments:

    IDA Sploiter is the clear winner of this year’s contest. Very nicely designed UI, clear and well-commented code, and good usage of the features provided by IDA API (choosers, forms, custom menu items and so on). Despite the complexity of the task, the plugin is pretty fast and robust. It will be a great tool in the arsenal of vulnerablity researchers.

    The other two plugins are simple, but well-made. They are a good example of how to use IDA APIs.
