A recent large scale DDoS (distributed denial of service) attack on DNS provider Dyn caused many sites to become temporarily inaccessible, including Twitter, Spotify, and a number of other important social media, e-commerce, news, and code-sharing sites. The attack was coordinated using a large group of compromised devices known as a “botnet”. Rather than computers, much of this botnet consisted of infected IoT (Internet of Things) devices such as security cameras.

Extended Discussion Questions

  • The Internet of Things provides connectivity to everyday objects. What concerns about the viability of this concept does this attack raise?
  • The article mentions that the source code for the Mirai botnet had been publicly released. What implications does this have for the future of IoT development?
  • At the time of this post, the source code is very easy to find online. What are the pros and cons of this kind of information being so easy to access?
