TaintInduce is a project which aims to automate the creation of taint propagation rules for unknown instruction sets.
One Engine To Serve 'em All: Inferring Taint Rules Without Architectural Semantics

In the Network and Distributed System Security Symposium 2019, San Diego, CA, US, Feb 2019.
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.
- capstone
- keystone-engine
- unicorn
- z3
- pyjsonrpc
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.

Edit squirrelflow.cfg. Put your server:port into this configure file.

Init FlowDB with rule directory:
from taintinduce.squirrelflowdb import SquirrelFlowDB
FlowDB = SquirrelFlowDB(rule_dir)
Check a set of rules:
FlowDB.check_rules(arch, insns)
Where arch is one of ['X86', 'AMD64', 'ARM64'] and insns is a set of instructions (raw bytes).
Get a rule of a given instruction.
squirrel_flow = FlowDB.get_rule(arch, insn)
