In October,
Microsoft awarded its top bounty reward of $100,000 for the first time to security researcher James Forshaw
for his discovery of a mitigation bypass exploit in Windows 8.1. This week, the company revealed that it has given out another $100,000 prize to researcher Yu Yang for finding and reporting variants on the Mitigation Bypass. The $100,000 reward was posted up quietly on
Microsoft's Bounty Hunter honor roll page and also revealed
via Twitter by Katie Moussouris, the company's Senior Security Strategist Lead.
