Microsoft ($3.1 trillion market value) & CrowdStrike ($63 billion market value) software update failure had caused massive disruptions to corporations & individuals using Windows computers worldwide on 19th July 2024, with hospitals, airlines, airports, banks & many others affected. CrowdStrike was founded by ex-executives of antivirus McAfee in 2012, and is a leading cybersecurity firm with software to defend against ransomware & hacks. CrowdStrike Founder & CEO George Kurtz: “I want to sincerely apologize directly to all of you for the outage. All of CrowdStrike understands the gravity and impact of the situation. We quickly identified the issue and deployed a fix, allowing us to focus diligently on restoring customer systems as our highest priority. The outage was caused by a defect found in a Falcon content update for Windows hosts. Mac and Linux hosts are not impacted. This was not a cyberattack. We are working closely with impacted customers and partners to ensure that all systems are restored, so you can deliver the services your customers rely on. CrowdStrike is operating normally, and this issue does not affect our Falcon platform systems. There is no impact to any protection if the Falcon sensor is installed. Falcon Complete and Falcon OverWatch services are not disrupted. We will provide continuous updates through our Support Portal. We have mobilized all of CrowdStrike to help you and your teams. If you have questions or need additional support, please reach out to your CrowdStrike representative or Technical Support. We know that adversaries and bad actors will try to exploit events like this. I encourage everyone to remain vigilant and ensure that you’re engaging with official CrowdStrike representatives. Our blog and technical support will continue to be the official channels for the latest updates. Nothing is more important to me than the trust and confidence that our customers and partners have put into CrowdStrike. As we resolve this incident, you have my commitment to provide full transparency on how this occurred and steps we’re taking to prevent anything like this from happening again.”

What Happened? On Friday, July 19, 2024 at 04:09 UTC, as part of regular operations, CrowdStrike released a content configuration update for the Windows sensor to gather telemetry on possible novel threat techniques. These updates are a regular part of the dynamic protection mechanisms of the Falcon platform. The problematic Rapid Response Content configuration update resulted in a Windows system crash. Systems in scope include Windows hosts running sensor version 7.11 and above that were online between Friday, July 19, 2024 04:09 UTC and Friday, July 19, 2024 05:27 UTC and received the update. Mac and Linux hosts were not impacted. The defect in the content update was reverted on Friday, July 19, 2024 at 05:27 UTC. Systems coming online after this time, or that did not connect during the window, were not impacted.
What Went Wrong and Why? CrowdStrike delivers security content configuration updates to our sensors in two ways: Sensor Content that is shipped with our sensor directly, and Rapid Response Content that is designed to respond to the changing threat landscape at operational speed. The issue on Friday involved a Rapid Response Content update with an undetected error.
