The Problem The “2024 Attack Intelligence Report” from the staff at Rapid7 [1] is a well-researched, well-written report that is worthy of careful study. Some key takeaways are:  53% of the over 30 new vulnerabilities that were widely exploited in 2023 and at the start of 2024 were zero-days. More mass compromise events arose from zero-day vulnerabilities than from n-day vulnerabilities.
