Last Friday, a large DDoS attack against Dyn caused many popular websites to be unreachable. The outage was discussed on mainstream news outlets. It is likely that you will be asked to brief your boss or your team about this attack. To help you out, we prepared a brief presentation that you may use as part of such a briefing. We publish the slides and a video of the presentation for you to use. You may modify the slides at will (add/remove to them) . But please give us credit if you use any of the material.

If you have any feedback, please let us know. We may update the presentation later this evening based on any suggestions we receive.
