Wpoison - Prevent E-Mail Address Harvesting
 Wpoison is a
CGI which can be used to help reduce the problem of
bulk junk e-mail on the Internet. Wpoison helps to combat the junk e-mail problem by thwarting the
efforts of junk e-mailers who regularly scan web pages, looking for target e-mail addresses to
harvest (which they subsequently bombard with junk e-mail).
Installation
Connect to your Virtual Private Server via
SSH,
su to root, and issue this command:
# vinstall wpoison
Add the mod_rewite
Apache Module to your web server by including the
following line in your web server configuration file (/www/conf/httpd.conf):
LoadModule rewrite_module modules/mod_rewrite.so
Usage
In order to properly implement a site inoculation, you will want to use a combination of empty
<a href> tags on your home page and throughout your web site similar to this:
<a href="/leeches/index.html"></a>
and then add lines similar to the following to your web server configuration file:
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} ^ExtractorPro.*
RewriteRule ^/.* /leeches/index.html [L]
RewriteCond %{HTTP_USER_AGENT} ^E-mailSiphon.*
RewriteRule ^/.* /leeches/index.html [L]
RewriteCond %{HTTP_USER_AGENT} ^eCatch.*
RewriteRule ^/.* /leeches/index.html [L]
To prevent legitimate
Web Robots
from indexing the Wpoison generated pages, create an entry in your robots.txt file
(or create the file in your ~/www/htdocs/ directory if it does not already exist) to
disallow the /leeches/ directory, like this:
User-agent: *
Disallow: /leeches/
