HttpServerEvilB

simple module

HttpServerEvilB

Demonstrates subclassing the server to create a custom site. This site is an attacker -- a puppetmaster -- which serves HTML pages containing attack code. In this case, we are simulating JavaScript attack code which prompts the unsuspecting browser to issue a number of requests for non-existing resources (random URLS) to the victim site. Delays are specified to simulate hiding the attack from the browser user by use of JavaScript timeouts or similar mechanisms. The generateBody virtual function is redefined to create a page containing the attack code.

This module definition has two additional parameters to the standard HttpServerDirect definition: * minBadRequests specifies the lower bound on bad requests caused to be sent to the victim by the browser. * maxBadRequests specifies the upper bound on bad requests caused to be sent to the victim by the browser.
