Palo Alto Networks CEO @nikesharora says he's more concerned about "trophy hunters" searching for the next security vulnerability than the PHP vulnerability itself. "I'm more concerned about what comes next. This is just one. There's more to come." "The problem is when you start seeing big things like this happen, you start finding people who are trophy hunters." "They're going to say, 'Where can I find the next PHP and prove to the world that I'm as smart as the last guy.'"
