The clock starts when a 0-day surfaces. How long before attackers strike?

Attackers often exploit new vulnerabilities before defenders can react, sometimes before the vulnerability even gets a public ID (a CVE).
Ethiack Zero is a live tracker of that race between attackers and defenders.

Zero is Ethiack’s public record of emerging 0-days. It turns early signals and patches into a working proof of exploit, then publishes how fast it validates each vulnerability (time-to-validateTime-to-Validate: how long it takes Zero to confirm a signal is exploitable, from first ingestion.) next to how fast attackers exploited it (time-to-exploitTime-to-Exploit: how long after public disclosure attackers take to exploit a vulnerability in the wild.).
