A total of six researchers have found 15 vulnerabilities within the preview version of Internet Explorer 11. And, Microsoft has paid them more than $28,000 to date.
IE 11 is an integral part of Windows 8.1 while at the same time it will most likely be a target for hackers and malware writers. For Microsoft, getting the security vulnerabilities squashed earlier rather than later is its primary motivation.
IE 11 for Windows 8 is scheduled to ship with Windows 8.1 on October 18.
