A comprehensive vulnerability analysis by “Mandiant” for 2023 uncovered “138” actively exploited “security vulnerabilities.”
They identified a significant prevalence of “97 zero-day vulnerabilities” and “41 n-day vulnerabilities” (the latter being exploited following the implementation of their respective patches). (those exploited after patch release).
The key finding was the considerable decrease in “Time-to-Exploit” (“TTE”), which fell to an average of just five days in 2023, compared to “32 days in 2021-2022,” “44 days in 2020-2021,” and “63 days in 2018-2019.”
The ratio of “n-day” to “zero-day” exploits changed to “30:70 in 2023,” down from the earlier ratio of about “38:62,” indicating a marked rise in “zero-day exploitation activities.”
Besides this, for “n-day vulnerabilities” specifically the exploitation timeline showed concerning trends:-
12% (5 vulnerabilities) were exploited within 24 hours of patch release.
29% (12 vulnerabilities) were exploited within a week.
56% were exploited within the first month.
A key case study is “CVE-2023-28121,” a vulnerability in the WooCommerce Payments plugin. This flaw highlighted how the availability of an exploit affected the timing of attacks, which occurred three months after it was disclosed.
Within three days of a weaponized exploit’s release, there were 1.3 million attacks per day.
