Disclaimer

We are currently in the process of rewriting the prototype to better serve our goal of providing an online taint service for different architectures. For people who are interested in the implementation used in the paper, feel free to contact us.

Requirements

Python3.6

• capstone
• keystone
• unicorn
• tqdm
• squirrel-framework

Usage

@TODO

taintinduce.py provides the inference interface and is the CLI tool to generate the rule.
Checkout the --help option on how to use the CLI tool.

python -m taintinduce.taintinduce c3 X86

taintinduce_worker.py is the compute process that SquirrelFlowDB uses.

python -m taintinduce.taintinduce_worker localhost 1234

Issue with virtual env (Ubuntu 16.04, Python 2.7.12)

When installing capstone and keystone-engine with pip in a virtual environment, the shared library files are expected to be in a folder like ~/.virtualenvs/<virtual_env>/lib/python2.7/site-packages/capstone. If not, you might run into an import error: ImportError: ERROR: fail to load the dynamic library.

A quick solution is to find where the library is and copy it to the expected path. For example, find - name libcapstone* inside ~/.virtualenvs/<virtual_env> and copy it to ~/.virtualenvs/<virtual_env>/lib/python2.7/site-packages/capstone.

Format of rules
