 Want to take your found ports and pipe them into Nmap for further analysis? That's possible. Want to run `smb-enum` if SMB is found open? Possible.

 The possibilities are endless -- and you can write scripts in whatever language you feel comfortable with.

+# Nmap nmap payload database -*- mode: fundamental; -*-
+# $Id$
+#
+# These payloads are sent with every host discovery or port scan probe
+# by default. This database should only include payloads that are
+# unlikely to crash services, trip IDS alerts, or change state on the
+# server. The idea behind these is to evoke a response using a payload.
+# Some of them are taken from nmap-service-probes.
+#
+# This collection of data is (C) 1996-2022 by Nmap Software LLC.  It
+# is distributed under the Nmap Public Source license as provided in
+# the LICENSE file of the source distribution or at
+# https://nmap.org/npsl/.  Note that this free license does not allow
+# incorporation of Nmap or its data files within proprietary
+# software. We sell a separate Nmap OEM for that as described
+# (including pricing) at https://nmap.org/npsl/.
+#
+# Each entry begins with a protocol (only "udp" is supported) followed
+# by a comma-separated list of ports, followed by one or more quoted
+# strings containing the payload. These elements may be broken across
+# several lines. For future expansion, additional keywords may follow
+# the payload data. Any data following one of these keywords must be on
+# the same line as the keyword so that unknown keywords can be ignored
+# by the parser. Currently this file contains some entries with the
+# "source" keyword to specify a desired source port, but it is not
+# honored by Nmap.
+#
+# Multiple payloads may be defined for a single protocol and port, in
+# which case they will be all be sent concurrently. There is a limit
+# of 255 payloads per port.
+#
+# Lines longer than 1024 characters will be ignored.
+#
+# Example:
+# udp 1234 "payloaddatapayloaddata"
