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:

Do not disable Tor unless replacing with an anonymous VPN.
Operate on an isolated network and on dedicated hardware.
Only execute samples in a suitable Sandbox (refer: https://github.com/phage-nz/malware-hunting/tree/master/sandbox).
Monitor for abuse of your API keys.

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*
