The Indian Computer Emergency Response Team (CERT) released a technical advisory, noting that "Windows hosts related to CrowdStrike agent 'Falcon Sensor' are facing outages and getting crashed due to a recent update received in the product."

The advisory detailed that affected Windows hosts are experiencing a "Blue Screen of Death (BSOD)" due to issues with the Falcon Sensor.

CERT also provided a workaround for the issue, advising users to boot Windows into Safe Mode or the Windows Recovery Environment, navigate to the C:\Windows\System32\drivers\CrowdStrike directory, locate and delete the file matching "C-00000291*.sys", and then boot the host normally.

The technical issues stemmed from the latest update of CrowdStrike, which has since been reverted by their team. However, services across various sectors were disrupted globally due to the combined technical problems at Microsoft and CrowdStrike, with millions of Microsoft Windows users encountering the "Blue Screen of Death" error, causing their systems to shut down or restart.

Microsoft attributed the issue to a "configuration change" in a segment of its Azure backend workloads, leading to connectivity failures between storage and compute resources, which in turn affected downstream Microsoft 365 services.

In a post on X, Microsoft stated, "Our services are still seeing continuous improvements while we continue to take mitigation actions."
