TROMMEL
MAJOR UPDATES Coming Soon!!!
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.
Dependencies
- Python-Magic - See documentation for instructions for Python3-magic installation
Usage
$ 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
Notes
- 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.
