00:05 WannaCry is perhaps the most infamous ransomware attack ever carried out. On May 12th, 2017, more than 200,000 computers were hit by the crypto worm, which tore a path of destruction across 150 countries, doing an estimated $4 billion in damages before security researcher Marcus Hutchins put a stop to it. And it never should have happened, because the vulnerability that let WannaCry spread with ease had been patched roughly two months before the outbreak.

00:42 Really, spending a few hours applying patch can save months of recovery, millions of dollars. The patch was free. The breach was not. That's what the math leaders need to keep in mind. A bunch of organizations just never applied that patch, teeing up WannaCry for perhaps the single most destructive day in cybersecurity history. Listen to the full episode wherever podcasts are found.

💡 Answer

No. Patch management remains essential because applying patches promptly can prevent major breaches and recovery costs.

🧠 AI Summary

Patch management is not dead: applying a free security patch promptly can prevent catastrophic ransomware damage. WannaCry infected more than 200,000 computers across 150 countries on May 12th, 2017, causing an estimated $4 billion in damages even though the exploited vulnerability had been patched roughly two months earlier.

🔑 Key Points
