Wordpress Fingerprinting

Wordpress comes bundled with the tinymce.js plug-in. Because this code changes every wordpress release, we are able to use its md5sum to determine a wordpress version against a target site. A perl script is below.

<syntaxhighlight lang="perl">

1. !/usr/bin/perl

use strict; use LWP::UserAgent; use HTTP::Request; use HTTP::Response; use Digest::MD5 qw(md5_hex);

my $domain = shift || die "No domain provided.\n";

my %ver_hash = (
