Silver – Mass Vulnerability Scanner Front End



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.


  • Resumable scanning
  • Slack notifcations
  • Multi-core utilization
  • Supports: IPs, CIDR & hostnames
  • 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.


Downloading Silver

git clone


External Programs

Python libraries

  • psutil
  • requests

Required Python libraries can be installed by executing pip3 install -r requirements.txt in Silver directory.


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

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/ file.


Before you start

warning Run Silver as root and with python3 i.e. with sudo python3 <your input>

warning Silver scans all TCP ports by default i.e. ports 0-65535. Use --quick switch to only scan top ~1000 ports.

Scan host(s) from command line

Scan top ~1000 ports
python3 --quick
Choose packets to be sent per seconds
python3 --rate 10000
Scan hosts from a file
python3 -i /path/to/targets.txt

Note: If your input file contains any hostnames, use the --resolve flag to tell Silver to resolve them to IPs because masscan only scans IPs.

Set max number of parallel nmap instances
python3 -i /path/to/targets.txt -t 4
