Find virtual hosts (vhosts) from IP addresses and hostnames

Last update: Jul 09, 2022

Overview

Features

Enumerate vhosts from a list of IP addresses and domain names.

Virtual Hosts are enumerated using the following process:

Supplied domains are resolved (all IPv4 and IPv6 addresses are added to scope)
All IP addresses are scanned for HTTP(S) services (using a default port list, see help)
Query external APIs (rapiddns) if enabled via --apis to find vhosts from IP or subdomains from domain
For all HTTP services, find vhosts using these techniques :
- TLS certificate parsing (for hosts with TLS service running)
  - CertCN
  - AltNames
- HTTP headers parsing (for detected HTTP services)
  - Location header
  - Access-Control-Allow-Origin header
  - Content-Security-Policy header
- JavaScript redirect (*.location=) when contains absolute URL
The whole process is repeated N times (--recursion-depth, default 2) on newfound IP addresses and hostnames. Increasing recursion depth will enumerate more hosts but may go out of scope.

Install

Example 2 :

# ./vhostmap.py -t targets.txt -p large --apis -o out

--apis : Use external API to find subdomains and virtual hosts (rapiddns)
-p large : Search for web services on a larger port list
-o out : Store results in "out" folder

Output folder contains multiple result files:

all-hostnames.txt : final hostname list, one by line
all-ips.txt : final list of all IP address associated with one or more hostnames, one by line
all-urls.txt : all valid web services found, one by line
hosts.txt : /etc/hosts format file associating IP addresses with vhosts
log.txt : tool output
