It was a DDoS attack using a botnet that took advantage of the IoT (Internet of Things). These botnets exist on computers all over the country but this one also included phones, internet tvs, tablets, etc. This one in particular focused on a specific brand of DVR. But I haven't seen any evidence it was "his supporters."

At first, it was unclear who or what was behind the attack on Dyn. But over the past few hours, at least one computer security firm has come out saying the attack involved Mirai, the same malware strain that was used in the record 620 Gpbs attack on my site last month. At the end September 2016, the hacker responsible for creating the Mirai malware released the source code for it, effectively letting anyone build their own attack army using Mirai.
Mirai scours the Web for IoT devices protected by little more than factory-default usernames and passwords, and then enlists the devices in attacks that hurl junk traffic at an online target until it can no longer accommodate legitimate visitors or users.
According to researchers at security firm Flashpoint, today’s attack was launched at least in part by a Mirai-based botnet. Allison Nixon, director of research at Flashpoint, said the botnet used in today’s ongoing attack is built on the backs of hacked IoT devices — mainly compromised digital video recorders (DVRs) and IP cameras made by a Chinese hi-tech company called XiongMai Technologies. The components that XiongMai makes are sold downstream to vendors who then use it in their own products.
“It’s remarkable that virtually an entire company’s product line has just been turned into a botnet that is now attacking the United States,” Nixon said, noting that Flashpoint hasn’t ruled out the possibility of multiple botnets being involved in the attack on Dyn.

As I noted in The Democratization of Censorship, to address the threat from the mass-proliferation of hardware devices such as Internet routers, DVRs and IP cameras that ship with default-insecure settings, we probably need an industry security association, with published standards that all members adhere to and are audited against periodically.
