Google security researchers uncover real-world exploitation of publicly unknown (zero-day) vulnerabilities. They say that more urgent action is appropriate for critical vulnerabilities under active exploitation. Each day an actively exploited vulnerability remains undisclosed to the public and unpatched, more computers will be compromised. 7 days is nice as a start, but actually bits and bytes know speed a little different than us puny humans. We will support researchers making details available so that users can take steps to protect themselves.”]
