Quicksplained: What is CrowdStrike? How is it linked to Microsoft's global IT outage?

You may have seen the “Blue Screen of Death” on your PC or laptop today – forcing it to shut down or restart. The firm in a support note stated, “Our Engineering teams are actively working to resolve this issue and there is no need to open a support ticket.” According to an alert sent by Crowdstrike to its clients and reviewed by Reuters, the company’s “Falcon Sensor” software is causing Microsoft Windows to crash and display a blue screen, known informally as the “Blue Screen of Death”. IT security firm also ran a recorded phone message on Friday saying it was aware of reports of crashes on Microsoft’s Windows operating system relating to its Falcon sensor. CrowdStrike CEO George Kurtz posted on social media platform X that the company “is actively working with customers impacted by a defect found in a single content update for Windows hosts.” He added: “This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed.” CrowdStrike was also mentioned in the infamous July 2019 phone call between then president Donald Trump and Ukrainian President Volodymyr Zelenskyy.
