The distributed denial-of-service (DDoS) attack was accomplished through numerous DNS lookup requests from tens of millions of IP addresses. [6] The activities are believed to have been executed through a botnet consisting of many Internet-connected devices —such as printers , IP cameras , residential gateways and baby monitors —that had ...
