When Time Turns Against You: Understanding Negative TTE for Cyber Resilience
The rapid exploitation of vulnerabilities by bad actors has rendered waiting for vendor patches an ineffective strategy.
Modern defense now focuses on resilience, containment, rapid detection and response, and recovery, as the window between vulnerability disclosure and exploitation has not only closed but reversed.
Attackers are now weaponizing flaws before patches exist, with
an estimated 63 dayspreviously considered a common safe window for patching before threat actors began exploiting disclosed vulnerabilities in 2019.
According to a Mandiant analysis,
70% of exploited vulnerabilities in 2023 were zero-day exploits, with the average time to exploit (TTE) dropping sharply to about
5 days.
This shift underscores the need for proactive cyber resilience measures.
