|
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.
