Mandiant analyzed 138 vulnerabilities that were disclosed in 2023 and that we tracked as exploited in the wild. Consistent with past analyses, the majority (97) of these vulnerabilities were exploited as zero-days (vulnerabilities exploited before patches are made available, excluding end-of-life technologies).
Forty-one vulnerabilities were exploited as n-days (vulnerabilities first exploited after patches are available). While we have previously seen and continue to expect a growing use of zero-days over time, 2023 saw an even larger discrepancy grow between zero-day and n-day exploitation as zero-day exploitation outpaced n-day exploitation more heavily than we have previously observed.
