As seen at Ars Technica , one Andre Freund was working along in his job as a security engineer at Microsoft with the intent of troubleshooting a 500 ms delay in a compression utility. Truly, the most exciting work in the world.
He found that it was due to a malware exploit being merged into open source which would have added a back door to every infected computer.
Great discussion on the exploit here .
So I guess Mr. Andre Freund is the Stanislav Petrov of the 21st century.
