Trommel : Sift Through Embedded Device Files to Identify Potential Vulnerable Indicators

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

It has also integrated vFeed which allows for further in-depth vulnerability analysis of identified indicators to enrich the output.

$ –help

Output TROMMEL results to a file based on a given directory. By default, only searches plain text files.

$ -p /directory -o output_file

Output TROMMEL results to a file based on a given directory. Search both binary and plain text files.

$ -p /directory -o output_file -b


  • The intended to assist researchers during firmware analysis to find potential vulnerabilities
  • Network defenders can benefit as well to assess devices on their network or for devices they plan to add to their network
  • Devices can include IoT (web cams, smart devices (light bulbs, plugs, switches, TVs, fridge, coffee maker, etc.)), SCADA/ICS, routers, really anything with an embedded flash chip that boots an OS on startup.
  • TROMMEL has been tested using Python3 on Kali Linux x86_64.
