Karonte : Static Analysis Tool To Detect Multi-Binary Vulnerabilities In Embedded Firmware

Karonte is a static analysis tool to detect multi-binary vulnerabilities in embedded firmware.

Research Paper

We present our approach and the findings of this work in the following research paper:

Repository Structure

There are four main directories:

• tool: python files
• firmware: firmware dataset
• configs: configuration files to analyze the firmware samples in the dataset
• eval: scripts to run the various evaluations on it.

Run

To run it, from the root directory, just run

• SYNOPSIS       python tool/karonte.py JSON_CONFIG_FILE [LOG_NAME]
• DESCRIPTION      runs karonte on the firmware sample represented by the JSON_CONFIG_FILE, and save the results in LOG_NAME
• EXAMPLE      python tool/karonte.py config/NETGEAR/r_7800.json      It runs karonte on the R7800 NETGEAR firmware

By default, results are saved in /tmp/ with the suffix Karonte.txt.

To inspect the generated alerts, just run:

python tool/pretty_print.py LOG_NAME

Docker

A dockerized version of it is ready to use can be found here
