If you're a software expert and interested in earning a nice load of money you may be interested in taking up Microsoft on their Security Bounty program for Windows 8.1. Under the program, Microsoft will pay up to $100,000 for security flaws found in Windows 8.1 Preview, and up to $11,000 for critical vulnerabilities in Internet Explorer 11. You can find the full details over here.
The following programs will launch on June 26, 2013:
Mitigation Bypass Bounty. Microsoft will pay up to $100,000 USD for truly novel exploitation techniques against protections built into the latest version of our operating system (Windows 8.1 Preview). Learning about new exploitation techniques earlier helps Microsoft improve security by leaps, instead of capturing one vulnerability at a time as a traditional bug bounty alone would. TIMEFRAME: ONGOING
BlueHat Bonus for Defense. Additionally, Microsoft will pay up to $50,000 USD for defensive ideas that accompany a qualifying Mitigation Bypass submission. Doing so highlights our continued support of defensive technologies and provides a way for the research community to help protect more than a billion computer systems worldwide. TIMEFRAME: ONGOING (in conjunction with the Mitigation Bypass Bounty).
Internet Explorer 11 Preview Bug Bounty. Microsoft will pay up to $11,000 USD for critical vulnerabilities that affect Internet Explorer 11 Preview on the latest version of Windows (Windows 8.1 Preview). The entry period for this program will be the first 30 days of the Internet Explorer 11 beta period (June 26 to July 26, 2013). Learning about critical vulnerabilities in Internet Explorer as early as possible during the public preview will help Microsoft make the newest version of the browser more secure. TIMEFRAME: 30 DAYS
