Security Hot Takes: CrowdStrike Outage Post-mortem

So, CrowdStrike blew up the internet! But what really happened and why was the impact so big? We’ll take you through the what, how and why of the CrowdStrike outage and cover some lessons we can all learn from the event.

What you'll learn

On July 19 2024, CrowdStrike pushed an update to security sensors on customer networks. The update contained “problematic content” on Windows devices that wasn’t identified by its internal testing processes. This led to a Windows ‘Stop Error’, or Blue Screen of Death (BSOD), on any device that received the update. Companies worldwide ground to a halt - airports halted flights and hospitals postponed medical procedures. But why?

In this course you’ll learn what went wrong, why the impact was so widespread, and how it was fixed. You’ll also understand why a relatively small update had such a significant impact, and what we can learn from this type of incident.
