Recently, when Let’s Encrypt began offering wildcard certificates, I began to wonder how this would change the encryption landscape. Would we see more companies encrypting more of their online assets? Would best practices for wildcard certificates scale to meet this new demand? Would we see a corresponding increase in phishing and other attacks?
As I was discussing these issues with a colleague, I was surprised and delighted to learn that the inventor of wildcard certificates, George Parsons, works with me at Venafi. To better understand some of the ramifications of the availability of free wildcard certificates, I sat down with George for a lengthy and informative chat about the history, use and abuse of wildcard certificates. Some of his anecdotes were amusing. And some were downright frightening. But I’m sure you’ll enjoy all of them as much as I did.
Here’s part one of my interview with George Parsons:
Have wildcard certificates outlived their usefulness? In the next two conversations with George Parsons, we’ll look at potential attacks that misuse wildcards and the ongoing temptation to use wildcards widely across enterprise networks.
