Overview of DNS-Based DDoS

Denial of service attacks have been around since the Internet was commercialized and some of the largest attacks ever launched relied on DNS, making headlines. But every day a barrage of smaller DNS-based attacks take down targets and severely stress the DNS ecosystem. Although DNS servers are not usually the target of attacks they are often disrupted so attention from operation teams is required. There is no indication the problem is going away and attackers continue to innovate. Most disturbing is bot-based DNS DDoS malware is already infiltrating consumer devices like home gateways and web connected cameras. It’s likely malware used in attacks is portable so more “Things” may be inducted.
