October 21, 2016 DDOS Attack

On October 21, 2016 a significant DDOS Attack occurred against DYN, a provider of DNS services for websites in the United States. This DDOS attack led to many web- sites to appear offline. The map below shows the scope of the impact of the DDOS on internet users. In many regions, the internet appeared unusable for several hours until DYN was able to mitigate the DDOS attack. The attack itself was carried out using basic devices connected to the internet. They include DVR’s, Blu-ray play- ers, TV’s, Webcams, etc. These devices are connected to the internet and have ex- tremely weak security protections. The attack is an example of the vulnerability of the internet and our reliance on it. It serves as an example to be used with staff about having backup and alternative plans available. It is likely that this attack impacted teachers who had planned les- sons utilizing affected websites. Additionally, for technology personnel it can be used as a case study in mitigating a DDOS attack and having an appropriate response.
