TROMMEL

TROMMEL sifts through embedded device files to identify potential vulnerable indicators. <br />

TROMMEL identifies the following indicators related to:

• Secure Shell (SSH) key files
• Secure Socket Layer (SSL) key files
• Internet Protocol (IP) addresses
• Uniform Resource Locator (URL)
• email addresses
• shell scripts
• web server binaries
• configuration files
• database files
• specific binaries files (i.e. Dropbear, BusyBox, etc.)
• shared object library files
• web application scripting variables, and
• Android application package (APK) file permissions.

TROMMEL has also integrated vFeed which allows for further in-depth vulnerability analysis of identified indicators. <br />

Dependencies

• Python-Magic
• vFeed Database - For non-commercial use, register and download the Community Edition database

Usage

$ trommel.py --help

Output TROMMEL results to a file based on a given directory

$ trommel.py -p /directory -o output_file

Notes

• The intended use of TROMMEL is to assist researchers during firmware analysis.
• TROMMEL has been tested using Python 2.7 on macOS Sierra and Kali Linux x86_64.
• TROMMEL was written with the intent to help with identifying indicators that may contain vulnerabilities found in firmware of embedded devices.
