The exploitation of zero-day vulnerabilities, flaws abused before the developers built a fix, is growing faster than the exploitation of n-day vulnerabilities (those for which a patch is already available), according to a report from Google Mandiant’s cybersecurity researchers, who describe it as a “worrying trend”.
The researchers recently analyzed 138 exploited vulnerabilities that were disclosed in 2023, and concluded that 70% were abused as zero-days, while 30% were n-days.
