Kill 'em All - DDoS Protection Total Annihilation!

Presented at DEF CON 21 (2013), Aug. 2, 2013, 3 p.m. (45 minutes)

With the advent of paid DDoS protection in the forms of CleanPipe, CDN / Cloud or whatnot, the sitting ducks have stood up and donned armors... or so they think! We're here to rip apart this false sense of security by dissecting each and every mitigation techniques you can buy today, showing you in clinical details how exactly they work and how they can be defeated.

Essentially we developed a 3-fold attack methodology:stay just below red-flag rate threshold,mask our attack traffics inconspicuous,emulate the behavior of a real networking stack with a human operator behind it in order to spoof the correct response to challenges,???PROFIT!We will explain all the required look-innocent headers, TCP / HTTP challenge-response handshakes,JS auth bypass, etc. etc. in meticulous details. With that knowledge you too can be a DDoS ninja! Our PoC attack tool "Kill-em-All" will then be introduced as a platform to put what you've learned into practice, empowering you to bypass all DDoS mitigation layers and get straight through to the backend where havoc could be wrought. Oh and for the skeptics among you, we'll be showing testing results against specific products and services.
