Passive SSH

Passive SSH logo

Passive SSH is an open source framework composed of a scanner and server to store and lookup the SSH keys and fingerprints per host (IPv4/IPv6/onion).

The key materials along fingerprints and hosts are stored in a fast-lookup database. The system provides an historical view of SSH keys seen but also common key materials reused on different IP addresses.

Features

  • A simple SSH scanner
  • A server storing key materials in a Redis database
  • A simple ReST API to lookup by SSH fingerprints (including hassh or host (IPv4, IPv6 or onion addresses)
  • Statistics of SSH banners and SSH fingerprints

Server Requirements

  • Python >= 3.6
  • Redis >5.0
  • tornado

Scanner Requirements

  • Python >= 3.6
  • D4 paramiko
  • pysocks (required to scan Tor hidden services)

Install

./install.sh
  • Install Redis and all pythons requirements.
  • All Python 3 code will be installed in a virtualenv (PSSHENV).

Tor proxy

The ssh scanner can be used with a Tor proxy to scan a host or an hidden service.

Don't forget to install the Tor proxy if you want to scan Tor hidden services: sudo apt-get install tor -y

Running

Launch the redis and the tornado server:

./LAUNCH -l

Manual scan

A SSH scanner is included to scan small networks or internal infrastructure.

. ./PSSHENV/bin/activate
cd bin/

# Scan a host
./ssh_scan.py -t <host: 10.0.0.12>

# Scan a network range
./ssh_scan.py -r <network range: 10.0.0.0/8>

API

An API is available to query the Passive SSH server.

By default, the tornado server for Passive SSH is running on port 8500.

curl http://localhost:8500/banners
