Microsoft has a bounty program that pays $150,000 to security researchers for ripping Windows and Internet Explorer apart. They use it to find vulnerabilities before malicious hackers do.

On Tuesday, the company just awarded $100,000 of the pot to just one guy, James Forshaw, a security researcher at Context Security.

There are no details of the security attack created by Forshaw. The company wants to fix the problem before talking about it. Forshaw says he found "an entire class of issues".

To get a $100,000 payout, a security researcher would have to come up with a "truly novel" way of breaking the security protections built into Windows 8.1. It had to be so big and bad that one guy could control a Windows PC over the Internet.
