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.

  • Usage

    $ --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 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.
