Uber recently poached a number of top security personnel from the social network, including Uber’s security chief Joe Sullivan. “Even with a team of highly-qualified and well trained security experts, you need to be constantly on the look-out for ways to improve,” Sullivan said in a statement about the initiative. “This bug bounty program will help ensure that our code is as secure as possible. And our unique loyalty scheme will encourage the security community to become experts when it comes to Uber.” The bug bounty program complements a number of other key cybersecurity hires that Uber has made in the past year. In addition to on-boarding 40 Carnegie Mellon roboticists, the company poached Charlie Miller and Chris Valasek, last year’s infamous Jeep Grand Cherokee hackers, from their respective roles at Twitter and cybersecurity firm IOActive.
