Hakrawler - Simple, Fast Web Crawler Designed For Easy, Quick Discovery Of Endpoints And Assets Within A Web Application

hakrawler is a Go web crawler designed for easy, quick discovery of endpoints and assets within a web application. It can be used to discover:

Forms
Endpoints
Subdomains
Related domains
JavaScript files

The goal is to create the tool in a way that it can be easily chained with other tools such as subdomain enumeration tools and vulnerability scanners in order to facilitate tool chaining, for example:

assetfinder target.com | hakrawler | some-xss-scanner

Features

Unlimited, fast web crawling for endpoint discovery
Fuzzy matching for domain discovery
robots.txt parsing
sitemap.xml parsing
Plain output for easy parsing into other tools
Accept domains from stdin for easier tool chaining
SQLMap-friendly output format
Link gathering from JavaScript files

Upcoming features

Cleaner code

Corben Leo added in functionality to pull links from JavaScript files

Thanks

codingo and prodigysml/sml555, my favourite people to hack with. A constant source of ideas and inspiration. They also provided beta testing and a sounding board for this tool in development.
tomnomnom who wrote waybackurls, which powers the wayback part of this tool
s0md3v who wrote photon, which I took ideas from to create this tool
The folks from gocolly, the library which powers the crawler engine
oxffaa, who wrote a very efficient sitemap.xml parser which is used in this tool
The contributors of LinkFinder where some awesome regex was stolen to parse links from JavaScript files.

Installation

Install Golang
Run the command below

go get github.com/hakluke/hakrawler

Run hakrawler from your Go bin directory. For linux systems it will likely be:

~/go/bin/hakrawler

Note that if you need to do this, you probably want to add your Go bin directory to your $PATH to make things easier!

Usage
Note: multiple domains can be crawled by piping them into hakrawler from stdin. If only a single domain is being crawled, it can be added by using the -domain flag.

$ hakrawler -h
Usage of hakrawler:
  -all
     Include everything in output - this is the default, so this option is superfluous (default true)
  -auth string
     The value of this will be included as a Authorization header
  -cookie string
     The value of this will be included as a Cookie header
  -depth int
     Maximum depth to crawl, the default is 1. Anything above 1 will include URLs from robots, sitemap, waybackurls and the initial crawler as a seed. Higher numbers take longer but yield more results. (default 1)
  -domain string
     The domain that you wish to crawl (for example, google.com)
  -forms
     Include form actions in output
  -js
     Include links to utilised JavaScript files
  -outdir string
     Directory to save discovered raw HTTP requests
  -plain
     Don't use colours or print the banners to allow for easier parsing
  -robots
     Include robots.txt entries in    output
  -schema string
     Schema, http or https (default "http")
  -scope string
     Scope to include:
     strict = specified domain only
     subs = specified domain and subdomains
     fuzzy = anything containing the supplied domain
     yolo = everything (default "subs")
  -sitemap
     Include sitemap.xml entries in output
  -subs
     Include subdomains in output
  -urls
     Include URLs in output
  -usewayback
     Query wayback machine for URLs and add them as seeds for the crawler
  -wayback
     Include wayback machine entries in output
  -linkfinder
      Search all JavaScript files for more links. Note that these will not be complete links, only relative. Parsing full links from JavaScript is too resource intensive.

Basic Example

Image:
Command: hakrawler -domain bugcrowd.com -depth 1

Full text output:

   $ hakrawler -domain bugcrowd.com -depth 1
