TROMMEL - Sift Through Embedded Device Files To Identify Potential Vulnerable Indicators

TROMMEL sifts through embedded device files to identify potential vulnerable indicators.
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.

  • Python-Magic - See documentation for instructions for Python3-magic installation
  • vFeed Database - For non-commercial use, register and download the Community Edition database

$ trommel.py --help
Output TROMMEL results to a file based on a given directory. By default, only searches plain text files.
$ trommel.py -p /directory -o output_file
Output TROMMEL results to a file based on a given directory. Search both binary and plain text files.
$ trommel.py -p /directory -o output_file -b

  • The intended use of TROMMEL is to assist researchers during firmware analysis.
  • TROMMEL has been tested using Python3 on 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.
