The Verge reports that of the 57 security flaws fixed in Microsoft's products on this week's edition of Patch Tuesday, 32 were bugs found by Google engineers.
Google engineers often find and report security vulnerabilities in Microsoft products, but they outdid themselves this month. Mateusz "j00ru" Jurczyk, a self-described "Windows hacker" and security engineer at Google, is credited for reporting 32 issues with Windows which Microsoft deemed "important," or one step below "critical." A second Google security engineer, Gynvael Coldwind, collaborated on reporting five of those bugs.
Google engineers are regularly credited in security updates, but this month's count is unusually high. (Google engineers reported a bug a month in October, November, and December, and none in January.) The total number of bugs Microsoft fixed this month is close to the all-time record of 64.
