Ph0neutria : Malware Zoo Builder That Sources Samples Straight From The Wild

Ph0neutria is a malware zoo builder that sources samples straight from the wild. Everything is stored in Viper for ease of access and manageability.

It aims to:

  • Limit the scope of crawling to only frequently updated and reliable sources.
  • Maximise the effectiveness of individual indicators.
  • Offer a single, reliable and well organised storage mechanism.
  • Not do work that can instead be done by Viper.

What does the name mean? “Phoneutria nigriventer” is commonly known as the Brazillian Wandering Spider: https://en.wikipedia.org/wiki/Brazilian_wandering_spider

Sources

As of version 1.0.0 all sources are created as ‘plugins’, found in the plugin sub-directory of the core scripts folder. Default sources are:

  • 0xffff0800’s Malware Library (credit: http://0day.coffee).
  • CleanMX (requires approved user-agent).
  • Cymon, which includes: Abuse.ch trackers, Bambenek C2 feed, Cyber Crime Tracker, Malc0de, URLVir and VX Vault.
  • Hybrid Analysis (requires vetted API key).
  • OTX.
  • Shodan, using the Malware Hunter search facility.
  • URLhaus.

Each plugin has parameters that must be completed prior to operation. You’ll find these at the top of each plugin file.

VirusTotal is a core component of ph0neutria that cannot be disabled. IP lists are fed into it to discover URL’s that are known for the IP’s. If you have a standard 5 request/minute API key then I’d encourage being conservative with what you feed it. You can do this by:

  • Reducing the number of Cymon feeds.
  • Reducing your OTX subscription count.
  • Setting the Hybrid Analysis SCORE_MIN parameter to 100.

Installation

The following script will install ph0neutria along with Viper and Tor:

wget https://raw.githubusercontent.com/phage-nz/ph0neutria/master/install.sh
chmod +x install.sh
sudo ./install.sh

Optional

Configure additional ClamAV signatures:

cd /tmp
git clone https://github.com/extremeshok/clamav-unofficial-sigs
cd clamav-unofficial-sigs
cp clamav-unofficial-sigs.sh /usr/local/bin
chmod 755 /usr/local/bin/clamav-unofficial-sigs.sh
mkdir /etc/clamav-unofficial-sigs
cp config/* /etc/clamav-unofficial-sigs
cd /etc/clamav-unofficial-sigs

Rename os..conf to os.conf, for example:

mv os.ubuntu.conf os.conf

Modify configuration files:

  • master.conf: search for “Enabled Databases” and enable/disable desired sources.
  • user.conf: UN-comment the required lines for sources you have enabled and complete them. user.conf overrides master.conf. You must UN-comment user_configuration_complete=”yes” once you’ve completed setup for the following commands to succeed.

mkdir /var/log/clamav-unofficial-sigs
clamav-unofficial-sigs.sh –install-cron
clamav-unofficial-sigs.sh –install-logrotate
clamav-unofficial-sigs.sh –install-man
clamav-unofficial-sigs.sh
cd /tmp/clamav-unofficial-sigs
cp systemd/* /etc/systemd
cd ..
rm -rf clamav-unofficial-sigs*

It’ll take a while to pull down the new signatures – during which time ClamAV may not be available.

Usage

Take precautions when piecing together your malware zoo:

Ensure Tor is started:

service tor restart

Start the Viper API and web interface:

cd /opt/viper
sudo -H -u spider python3 viper-web

Take note of the admin password that is created when Viper is started. Use this to log into http://<viper IP\>:<viper port>/admin (default: http://127.0.0.1:8080/admin) and retrieve the API token from the Tokens page.

The main Viper web interface will be available at http://<viper IP>:<viper port> (default: http://127.0.0.1:8080).

  • Complete the config file at: /opt/ph0neutria/core/config/settings.conf
  • Complete the parameters at the top of each plugin. If you wish to disable the plugin, set DISABLED = True: /opt/ph0neutria/core/plugins/*.py

Start ph0neutria:

cd /opt/ph0neutria
sudo -H -u spider python3 run.py

You can press Ctrl+C at any time to kill the run. You are free to run it again as soon as you’d like – you can’t end up with database duplicates.

To run this daily, create a script in /etc/cron.daily with the following:

!/bin/bash
cd /opt/ph0neutria && sudo -H -u spider python3 run.py*
