Patch All the Things!

What is a zero-day exploit?

I'm glad you asked! These are the most critical vulnerabilities in a software application. A flaw is present that the vendor doesn't know about, but bad guys do, and they are already taking advantage of it.

Apparently there is Big Money in zero-days. This interesting article talks about the "multi-millionaire market" for zero-days.
