Microsoft has said it is taking "mitigation action" to deal with "the lingering impact" of the outage.
How Did The Outage Happen?
The outage caused Microsoft laptops and PCs to show a “blue screen of death”, meaning users were unable to access their systems.
CrowdStrike CEO George Kurtz said the company was working to fix problems created for Windows users of its tools by a recent update in a post on the social media platform X.
"CrowdStrike is actively working with customers impacted by a defect found in a single content update for Windows hosts. Mac and Linux hosts are not impacted. This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed. We refer customers to the support portal for the latest updates and will continue to provide complete and continuous updates on our website. We further recommend organisations ensure they’re communicating with CrowdStrike representatives through official channels. Our team is fully mobilised to ensure the security and stability of CrowdStrike customers."CrowdStrike CEO George Kurtz
