CNNfn's Business Unusual was a business-focused program that took on the stories shaping the new economy — and in March 2000, no story was bigger than the DDoS attacks that had just brought down Yahoo, eBay, Amazon, CNN, and other internet leaders. Stuart McClure's appearance on the program brought exactly what the moment needed: a credible, clear-eyed technical voice who could explain the attacks in terms that made sense to business audiences.
The context was distinctive. Business Unusual's audience was not the general consumer of CNN Morning News or the specialist reader of security trade press — it was the emerging class of business leaders and investors who were betting their companies and their capital on the internet. For them, the February and March 2000 DDoS attacks raised urgent questions: Was the internet infrastructure fundamentally unsafe? Could companies depend on it? What would it take to protect against this kind of attack?
Stuart addressed these questions with the practical authority that came from co-authoring Hacking Exposed the previous year. He was able to explain the mechanics of distributed denial-of-service attacks — the botnet of compromised machines, the amplified traffic flood, the overwhelmed servers — without losing a business audience that needed context more than technical depth. And he could situate those mechanics in the economic reality: yes, this was serious; no, it was not the end of the internet; here is what good security practice looks like; here is what companies need to do.
The March 2000 Business Unusual appearance was part of a concentrated period of national media presence for Stuart as the internet security crisis played out in real time. These appearances collectively established his reputation as a trusted voice for business audiences on complex security questions — a role he has continued to play for the decades since.
