EZ-Wave — Exploiting Z-Wave Networks
EZ-Wave: Tools for Evaluating and Exploiting Z-Wave Networks using Software-Defined Radios.
-
ezstumbler
passive Z-Wave network discovery and active network enumeration
-
ezrecon
Z-Wave device interrogation including: – Manufacturer and device name – Software/firmware versions – Supported Z-Wave command classes – Device configuration settings
-
ezfingerprint
determines device’s Z-Wave module generation (3rd or 5th gen) using a PHY layer manipulation technique (preamble length manipulation).

Requirements
- Python 2.7
- GNU Radio 3.7+ (recommend Pybombs:https://gnuradio.org/redmine/projects/pybombs/wiki/QuickStart)
- Wireshark 1.12+ (https://code.wireshark.org/review/wireshark)
- Mercurial (sudo apt-get install mercurial -y)
- **Default configuration is for 2 HackRF One SDRs. Other SDRs can be use by modifying the GRC files accordingly post install ($HOME/.scapy/radio).
- OsmocomSDR (https://sdr.osmocom.org/trac/wiki/GrOsmoSDR)
- HackRF host software (https://github.com/mossmann/hackrf/tree/master/host)
Installation
The setup script will clone Scapy-radio (https://bitbucket.org/cybertools/scapy-radio/) and modify installation files
./setup.sh

Install Scapy-radio
cd $HOME/scapy-radio
./install.sh scapy
./install.sh blocks
Open [gnuradio prefix]/etc/gnuradio/conf.d in a text editor and append “:/usr/local/share/gnuradio/grc/blocks” to global_blocks_path
./install.sh grc
Install Wireshark dissector
Copy all files in EZ-Wave/setup/wireshark to [wireshark]/epan/dissectors
cd [wireshark]
./autogen.sh
./configure
make
sudo make install
sudo ldconfig
Usage
ezstumbler
ezstumbler.py [-h, –help] [-p, –passive] [-t, –timeout] [-a, –active] [–homeid] -p, –passive Conduct a passive scan for a set time (secs) -t, –timeout Timeout (secs) for scans, default=60 -a, –active Conduct an active scan for a set time (secs) –homeid 4 byte HomeID to scan (ex: 0x1a2b3c4d)
30s passive followed by active scan:
ezstumbler.py --timeout=30
passive scan:
ezstumbler.py --passive
active scan:
ezstumbler.py --active --homeid=0x1a2b3d4e
