Statement from George Kurtz, CEO of CrowdStrike
“CrowdStrike is actively assisting customers affected by a defect identified in a recent content update for Windows hosts. This issue does not impact Mac or Linux hosts and is not related to a security incident or cyberattack. We have identified and isolated the problem, and a fix has been deployed. We advise customers to check the support portal for the latest updates and to continue monitoring our website for comprehensive and ongoing information. We also recommend that organizations communicate with CrowdStrike representatives through official channels to ensure they receive accurate information. Our team is fully mobilized to guarantee the security and stability of our customers’ systems.”
Statement from Microsoft
“We’re working around the clock and providing ongoing updates and support. Additionally, CrowdStrike has helped us develop a scalable solution that will help Microsoft’s Azure infrastructure accelerate a fix for CrowdStrike’s faulty update. We have also worked with both AWS and GCP to collaborate on the most effective approaches.
While software updates may occasionally cause disturbances, significant incidents like the CrowdStrike event are infrequent. We currently estimate that CrowdStrike’s update affected 8.5 million Windows devices, or less than one percent of all Windows machines. While the percentage was small, the broad economic and societal impacts reflect the use of CrowdStrike by enterprises that run many critical services.
This incident demonstrates the interconnected nature of our broad ecosystem — global cloud providers, software platforms, security vendors and other software vendors, and customers. It’s also a reminder of how important it is for all of us across the tech ecosystem to prioritize operating with safe deployment and disaster recovery using the mechanisms that exist. As we’ve seen over the last two days, we learn, recover and move forward most effectively when we collaborate and work together. We appreciate the cooperation and collaboration of our entire sector, and we will continue to update with learnings and next steps.”
