Dyn loses 14,500 domains following Mirai DDoS attack

The Security Ledger has reported that around 14,500 Internet domains have stopped using managed DNS services from Dyn, following the Mirai DDoS attack in October 2016.

Multiple large DDoS attacks against Dyn took down multiple prominent websites, including Twitter, PayPal, Reddit, and Amazon.

The DDoS attacks were conducted in three waves and were targeted at Dyn’s managed DNS infrastructure.

“Dyn experiencing a DDoS attack. While it’s not uncommon for Dyn’s Network Operations Center (NOC) team to mitigate DDoS attacks, it quickly became clear that this attack was different,” said Kyle York, Dyn’s Chief Strategy Officer.

Approximately two hours later, the Dyn NOC team was able to mitigate the attack and restore service to customers.

During that time, Internet users directed to Dyn servers on the east coast of the US were unable to reach several of Dyn’s customers’ sites.

The Security Ledger said the attacks “had lasting implications for Dyn – and other Internet companies like it – as new data suggests that around 8% of the web domains relying on Dyn’s managed DNS service dropped the service in the immediate aftermath of the attack”.
