The script http-grep can select different patterns for extraction by setting the script argument http-grep.builtins. The built-in patterns are:

• E-mail
• Phone
• Mastercard
• Discover
• VISA
• Amex
• SSN
• IP address

Pass a table of patterns to http-grep.builtins to select any of the built-in patterns:

$nmap -p 80 <target> --script http-grep --script-args 'http-grep.builtins ={"mastercard", "discover"}  

By just setting http-grep.builtins, all patterns will be enabled:

$nmap -p80 --script http-grep --script-args http-grep.builtins <target>
