CrowdStrike Update Triggers BSOD Issue Affecting Airlines and Banks

Millions of Windows users worldwide are currently facing the Blue Screen of Death (BSOD) issue, causing system shutdowns or restarts. This problem has been linked to a recent CrowdStrike update, impacting various organizations, financial institutions, and government agencies globally. Notably, several Indian airlines have reported disruptions, informing passengers about the issue on X (formerly Twitter).

Understanding Blue Screen of Death (BSOD): BSOD errors, also known as STOP code errors, occur due to critical issues forcing Windows to shut down or restart. These errors can be triggered by hardware or software problems, often displaying messages like "Windows has been shut down to prevent damage to your computer."

Impact on Industries: Large U.S. airlines, including American Airlines, Delta Airlines, and United Airlines, have issued ground stops due to communication problems. Additionally, several airports experienced significant technical issues with check-in kiosks for airlines such as IndiGo, Akasa Air, SpiceJet, and Air India Express.

The Widespread Issue: The problem is widespread, affecting workplaces and public entities like airlines, banks, and media companies. It has been identified that Windows PCs using a specific cybersecurity solution from CrowdStrike are the main targets of this outage.

Microsoft's Response: Microsoft has acknowledged the issue and is working on mitigations. The company, via its verified X handle Microsoft 365 status, has shared updates on the outage and ongoing investigations. Microsoft Azure has identified that Virtual Machines (VMs) running Windows Client and Windows Server with the CrowdStrike Falcon agent installed may encounter BSOD and become stuck in a restarting state.
