Karonte – A 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.

Repository Structure
There are four main directories:

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

Run Karonte
To run karonte, 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 Karonte ready to use can be found here
