In this episode, returning guest Abhistha -- now Assistant Professor in network security at the University of Utwente  -- digs into his latest research on the real economic impact of distributed denial-of-service (DDOS) attacks such as the Mirai botnet. With the internet-of-things continuing to grow as an attack surface, and compromised devices increasing both in number and processing capacity, we take an in-depth look at the underground economics of botnets -- and why some large corporations may not be owning up to the true extent of the threat to their bottom line.
