New data suggests that some 14,500 web domains stopped using Dyn’s Managed DNS service in the immediate aftermath of an October DDoS attack by the Mirai botnet. That’s around 8% of the web domains using Dyn Managed DNS… “The data show that Dyn lost a pretty big chunk of their customer base because they were affected by (Mirai),” said Dan Dahlberg, a research scientist at BitSight Technologies in Cambridge, Massachusetts… BitSight, which provides security rating services for companies, analyzed a set of 178,000 domains that were hosted on Dyn’s managed DNS infrastructure before and immediately after the October 21st attacks.
It’s possible some of those domains later returned to Dyn — and the number of actual customers may be smaller than the number of hosted domains. But in the end it may not have mattered much, since Dyn was acquired by Oracle the next month, and TechCrunch speculates that the deal had already been set in motion before the attack. They also add that “Oracle, of course, is no stranger to breaches itself: in August it was found that hundreds of its own computer systems were breached.”
