Detection Pattern Guide

Signatures use regex patterns to match technology fingerprints. Include at least one detection pattern. More patterns = higher confidence.

scriptSrc

Regex matching <script src> or <link href> URLs

cdn\\.example\\.com/sdk\\.js

meta

Object: meta tag name → value regex. Use "generator" for CMS detection

{ "generator": "ExampleCMS ([\\d.]+)\\;version:\\1" }

headers

Object: HTTP header name → value regex. Empty string means "header exists"

{ "X-Powered-By": "ExampleFramework" }

js

Object: JavaScript global variable path → value regex

{ "Example.version": "(.+)\\;version:\\1" }

html

Regex matching raw HTML content (use sparingly — can cause false positives)

<div[^>]+class="example-widget"

dom

CSS selector to match DOM elements

link[href*='example.com']

cookies

Object: cookie name → value regex. Empty string means "cookie exists"

{ "_example_session": "" }

dns

Object: DNS record type → value regex

{ "TXT": "example-site-verification" }

Version extraction: use ([\\d.]+)\\;version:\\1. Confidence override: append \\;confidence:50.
