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 - karonte-viz: script to visualize the results produced by Karonte

Run Karonte

To run karonte, from the root directory, just run

SYNOPSIS       python tool/karonte.py JSONCONFIGFILE [LOG_NAME]

DESCRIPTION      runs karonte on the firmware sample represented by the JSONCONFIGFILE, 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
