In a DDos, traffic increases so quickly over so many nodes simultaneously that servers can't do what they're supposed to do, which is basically figure out where all the packets are supposed to go. The theory has sort of always been that no DDoS, or even multiple DDos (es?) could shut down - say - the internet.
So, flashback a bit to Friday 10/21. A coordinated series of DDoS attacks overwhelmed the services of a huge internet "hub" kind of company called Dyn; here's their statement about it. You may be thinking, "I hate acronyms. What do I care?" Well, Dyn is so big and tied in to so many other networks that the attack disrupted at least some part of service (according to Gizmodo) at a TON of sites including:
- CNN
- Github
- HBO Now
- Iheart.com (iHeartRadio)
- PayPal
- People.com
- Playstation Network
- Spotify
- The Verge
- Wired.com
- Wix Customer Sites
- Yelp
- Netflix
- New York Times
- Weather.com
- WSJ.com
The FBI and other law-enforcement agencies have said they're investigating the attacks. What do you see as the possible ramifications, the possibility for future threats, that this kind of attack might suggest?
