mwebfp – Massive Web Fingerprinter

The “LowNoiseHG (LNHG) Massive Web Fingerprinter” (“mwebfp” from now on) was conceived in July 2013 after realizing the usefulness of webserver screenshots to pentesters, during an engagement with large external or internal IP address ranges, as a quick means of identification of critical assets, easily-exploitable services, forgotten/outdated servers and basic network architecture knowledge of the target.


The basic operation of mwebfp consists of the processing of an input (targets and TCP ports) that is then used to identify open web server ports with the help of a powerful portscanner (nmap). All ports found open are then analyzed (on HTTP and HTTPS) and all relevant webserver information is recorded, as well as a screenshot of the rendered webpage (as if it is seen from a broswer).

Special Features

  • Input
    • Target(s) can be IP address(es), IP address range(s), server name(s), etc.
    • Target(s) can be provided directly on the command-line or on a file
  • Port Definition
    • Default ports are 80 (HTTP) and 443 (HTTPS), but any port can be easily configured at runtime
  • Output
    • All output files and related support files for the scan are saved on a directory configured at runtime by the user
    • Currently, mwebfp exports results on a CSV file (Easily usable on MS Excel) only
  • Virtual Hosts
    • If requested at runtime, mwebfp will find all virutally hosted domains and webpages for the target server
  • Webserver Screenshots
    • If requested at runtime, mwebfp will grab screenshots of all found web pages (Graphical UI under Linux is required)
