Host-Extract - Enumerate All IP/Host Patterns In A Web Page

Tweet

This little ruby script tries to extract all IP/Host patterns in page response of a given URL and JavaScript/CSS files of that URL. With it, you can quickly identify internal IPs/Hostnames, development IPs/ports, cdn, load balancers, additional attack entries related to your target that are revealed in inline js, css, html comment areas and js/css files. This is unlike web crawler which looks for new links only in anchor tags (<a) or the like. (you might miss many additional targets if you ever use such web crawler or other GUI-based tools that shows you your main target and its relationship with its linked sub/off-site domains) In some cases, host-extract may give you false positives when there are some words like - main-site_ver_10.2.1.3.swf. With -v option, you can ask the tool to output html view-source snippets for each IP/Domain extracted. This will shorten your manual analysis time. USAGE: ruby host-extract.rb URL [option] Usage: host-extract [options] -a find all ip/host patterns -j scan all js files -c scan all css files -v append view-source html snippet for manual verification Download Host-Extract
