An issue with U.S. cybersecurity software company CrowdStrike led to the widespread global issue. “This is not a security incident or cyberattack,” CrowdStrike CEO George Kurtz clarified on Friday. A defect had been found in a single content update for Windows hosts which was attributed later to the Falcon Sensor product, he added. The issue had come down to a bug in a single update causing the cascading effect.
CrowdStrike calls Falcon “the CrowdStrike platform purpose-built to stop breaches via a unified set of cloud-delivered technologies that prevent all types of attacks—including malware and much more.”
