Silver – Mass Scan IPs For Vulnerable Services

masscan is fast, nmap can fingerprint software and vulners is a huge vulnerability database. Silver is a front-end that allows complete utilization of these programs by parsing data, spawning parallel processes, caching vulnerability data for faster scanning over time and much more.

Note: Silver isn’t compatible with Python 2.

Features

• Resumable scanning
• Slack notifcations
• multi-core utilization
• Vulnerability data caching
• Smart Shodan integration*

*Shodan integration is optional but when linked, Silver can automatically use Shodan to retrieve service and vulnerability data if a host has a lot of ports open to save resources. Shodan credits used per scan by Silver can be throttled. The minimum number of ports to trigger Shodan can be configured as well.

Requirements

• nmap
• masscan

Usage

Note: Silver scans all TCP ports by default i.e. ports 0-65535.

Scan host(s) from command line

python3 silver.py 127.0.0.1
python3 silver.py 127.0.0.1/22
python3 silver.py 127.0.0.1,127.0.0.2,127.0.0.3

Scan top ~1000 ports

python3 silver.py 127.0.0.1 --quick

Scan hosts from a file

python3 silver.py -i /path/to/targets.txt

Set max number of parallel nmap instances

python3 silver.py -i /path/to/targets.txt -t 4

Configuration
Slack WebHook, Shodan API key and limits can be configured by editing respective variables in /core/memory.py

Setting up Slack notifications

• Create a workspace on slack, here
• Create an app, here
• Enable WebHooks from the app and copy the URL from there to Silver’s /core/memory.py file.
