This year is on track to be a record one for zero-day vulnerabilities, the term for software flaws that are being actively exploited in the wild and do not have a fix. About 21 have been discovered so far, and if that pace continues, the year could end with more than 60. Google’s Project Zero, which was launched in 2014, is a team of researchers that focuses on finding these high-impact flaws before they’re maliciously exploited. The group’s motto is “make zero day hard””]
