Ecuador's government confirms that they cut Julian Assange's Internet connection, after another batch of email exchanges (involves Ms Hillary Clinton) was leaked by Wikileaks, at its embassy in London.
As per news, the DDoS attack was generated to take revenge for this.

Wikileaks requested the attackers to stop the DDoS attack immediately.

Type of attack
Latest reports indicate that the DDoS attack on Dyn infrastructure (particularly DNS servers) was generated using infected IoT devices (like CCTVs, WebCam and others). The source code of one such malware named Mirai was released on the Internet recently. It is speculated that this malware was used for generating the attack.

  • Would such an opensource alone be sufficient to launch the attack? (I guess no, for otherwise there would be a real catastrophe.) Commented Oct 31, 2016 at 7:33
  • Mirai was one of the confirmed malware which was used to launch an attack on Dyn Infrastructure on Fri 21. There may be other malware (or other methods) but those were not confirmed by Dyn (or other security researchers). Commented Oct 31, 2016 at 7:35
  • My ignorant's conjecture is that that malware code is apprently not self-sufficient for achieving the reported success. For otherwise any kids would now be able to generate chaos on the Internet. Commented Oct 31, 2016 at 7:54
  • They are. in the post releasing the source code, the user anna_senpai claims that at release the bot pulls 300k devices from telnet alone, but it's dropping. Conservatively assuming these can output 1Mb/s, they can deliver a 300Gb/s DDoS
