To some it may have passed under the radar, for others it might be of interest.
Microsoft has released a bug bounty program for hackers, white hats, bug hunters and security researchers alike to discover, find and report vulnerabilities to Microsoft to strengthen the Microsoft portfolio.
Microsoft having dominated the market for home users and business computers have long been a favored target for cyber criminals, hobby hackers and other nefarious operatives. Meaning that just a zero-day vulnerability or any breach can cause a crisis like the recent WannaCry ransomware attack.
Microsoft has previously had bug bounty programs, but mostly they have been limited in time, or for specific suites.
