Google announces Project Zero, a team of researchers who searches the web for vulnerabilities and malware. When a threat is found, the software vendor is notified and it is posted on a publicly available database:
You should be able to use the web without fear that a criminal or state-sponsored actor is exploiting software bugs to infect your computer, steal secrets or monitor your communications. Yet in sophisticated attacks, we see the use of “zero-day” vulnerabilities to target, for example, human rights activists or to conduct industrial espionage. This needs to stop. We think more can be done to tackle this problem. Project Zero is our contribution, to start the ball rolling.
