Microsoft Wants You to Rethink Your Approach to Cyber Defense
TechTarget, Tuesday, August 19th, 2025
Microsoft says an exploit now costs $3.61 and 21 minutes to build, and MSRC volume is up ninefold.
Microsoft's David Weston argued that traditional vulnerability remediation is obsolete now that AI has driven exploit development down to roughly $3.61 and 21 minutes.
MSRC is processing nine times more vulnerabilities than it was in March, and Microsoft's own MDASH tool automatically generated 182 exploits from 200 discovered Linux kernel flaws.
Weston's prescription is to stop treating reactive patching as the primary defense and invest in inherently resilient systems, pointing to memory-safe languages such as Rust that would eliminate roughly 70% of what currently gets patched.
Rather than continuing the hand-to-hand combat of detection and evasion cycles, he wants enterprises to spend on prevention and secure-by-design architecture.
