With the Fast Flux technique, bad guys can leverage thousands of disposable drone machines as intermediaries, rapidly swapping among different systems, confounding investigators who try to trace back a constantly fluctuating set of targets. In normal phishing attacks, the name in the link Web server at one of these IP addresses. The machines at those addresses, however, are actually bot-infected victim machined running a transparent Web proxy.
