Template

Template is a YAML input file which defines all the requests and other metadata for a template.

id string

ID is the unique id for the template.

Good IDs

A good ID uniquely identifies what the requests in the template are doing. Let's say you have a template that identifies a git-config file on the webservers, a good name would be git-config-exposure. Another example name is azure-apps-nxdomain-takeover.

Examples:

data string

Data is the data to send as the input.

It supports DSL Helper Functions as well as normal expressions.

Examples:

data: TEST

Type is the type of input specified in data field.

Default value is text, but hex can be used for hex formatted data.

Valid values:

  • hex

  • text

read int

Read is the number of bytes to read from socket.

This can be used for protocols which expect an immediate response. You can read and write responses one after another and eventually perform matching on every data captured with name attribute.

The network docs highlight more on how to do this.

Examples:

read: 1024

name string

Name is the optional name of the data read to provide matching on.

Examples:

name: prefix
