The Decompiler Artificial Intelligence Language Assistant (DAILA) is a tool for adding AI to decompilers.
Project description
DAILA
The Decompiler Artificial Intelligence Language Assistant (DAILA) is a unified interface for AI systems to be used in decompilers. Using DAILA, you can utilize various AI systems, like local and remote LLMs, all in the same scripting and GUI interfaces. Power up your decompilation experience with AI!
DAILA provides a lifted interface, relying on the BinSync library LibBS to abstract away the decompiler. All decompilers supported in LibBS are supported in DAILA, which currently includes IDA, Ghidra, Binja, and angr-management. Currently, there are two AI systems supported in DAILA: OpenAI and VarBERT, the latter of which is a local model for renaming variables in decompilation published in S&P 2024.
Installation
Install our library backend through pip and our decompiler plugin through our installer:
pip3 install dailalib && daila --install
This will also download the VarBERT models for you through the VarBERT API.
Ghidra Extra Steps
You need to do a few extra steps to get Ghidra working. Next, enable the DAILA plugin:
- Start Ghidra and open a binary
- Goto the
Windows > Script Manager
menu - Search for
daila
and enable the script
You must have python3
in your path for the Ghidra version to work. We quite literally call it from inside Python 2.
You may also need to enable the $USER_HOME/ghidra_scripts
as a valid scripts path in Ghidra.
Manual Install (if above fails)
If the above fails, you will need to manually install.
To manually install, first pip3 install dailalib
on the repo, then copy the daila_plugin.py file to your decompiler's plugin directory.
Usage
DAILA is designed to be used in two ways:
- As a decompiler plugin with a GUI
- As a scripting library in your decompiler
Decompiler GUI
With the exception of Ghidra (see below), when you start your decompiler you will have a new context menu which you can access when you right-click anywhere in a function:
If you are using Ghidra, go to Tools->DAILA->Start DAILA Backend
to start the backend server.
After you've done this, you can use the context menu as shown above.
Scripting
You can use DAILA in your own scripts by importing the dailalib
package.
Here is an example using the OpenAI API:
from dailalib import OpenAIAPI
from libbs.api import DecompilerInterface
deci = DecompilerInterface.discover_interface()
ai_api = OpenAIAPI(decompiler_interface=deci)
for function in deci.functions:
summary = ai_api.summarize_function(function)
Supported AI Backends
OpenAI (ChatGPT)
DAILA supports the OpenAI API. To use the OpenAI API, you must have an OpenAI API key.
If your decompiler does not have access to the OPENAI_API_KEY
environment variable, then you must use the decompiler option from
DAILA to set the API key.
Currently, DAILA supports the following prompts:
- Summarize a function
- Rename variables
- Rename function
- Identify the source of a function
VarBERT
VarBERT is a local BERT model from the S&P 2024 paper ""Len or index or count, anything but v1": Predicting Variable Names in Decompilation Output with Transfer Learning". VarBERT is for renaming variables (both stack, register, and arguments) in decompilation. To understand how to use VarBERT as a library, please see the VarBERT API documentation. Using it in DAILA is a simple as using the GUI context-menu when clicking on a function.
