"It is said that eternal vigilance is the price of liberty...We must continue to work together to make the internet a more resilient place to work, play and communicate," wrote Dyn's Chief Strategy Officer in a Saturday blog post. An anonymous reader reports: Dyn CSO Kyle York says they're still investigating Friday's attack, "conducting a thorough root cause and forensic analysis" while "carefully monitoring" for any additional attacks. In a section titled "What We Know," he describes "a sophisticated attack across multiple attack vectors and internet locations...one source of the traffic for the attacks were devices infected by the Mirai Botnet. We observed 10s of millions of discrete IP addresses associated with the Mirai botnet that were part of the attack." But he warns that "we are unlikely to share all details of the attack and our mitigation efforts to preserve future defenses." He posted a timeline of the attacks (7:00 EST and 12:00 EST), adding "While there was a third attack attempted, we were able to successfully mitigate it without customer impact... We practice and prepare for scenarios like this on a regular basis, and we run constantly evolving playbooks and work with mitigation partners to address scenarios like these." He predicts Friday's attack will be seen as "historic," and acknowledges his staff's efforts to fight the attack as well as the support received from "the technology community, from the operations teams of the world's top internet companies, to law enforcement and the standards community, to our competition and vendors... On behalf of Dyn, I'd like to extend our sincere thanks and appreciation to the entire internet infrastructure community for their ongoing show of support." Online businesses may have lost up to $110 million in sales and revenue, according to the CEO of Dynatrace, who tells CNN more than half of the 150 websites they monitor were affected.
