What is CroudStrike and What Caused the CroudStrike Falcon BSOD error that stopped the world?
An insane number of Windows devices globally are crashing with a Blue Screen of Death (BSOD) because of a single CrowdStike Falon Sensor file. The File is called “csagent.sys”. Falcon Sensor is a simple software agent deployed on endpoints (such as computers and servers) to provide real-time protection against a wide range of cyber threats. Which is hilarious to think about because the very tool designed to protect critical systems around the world is the one that brought it all to a grinding halt. Something hackers probably couldn't have pulled off.
Seeing as this issue seems to only have a manual fix (at the time of writing) solving the problem is going to take a long time to fix fully. Airlines have already flipped to manual boarding doing everything by hand using paper and pens like it's the 40s again. As things evolve we'll keep you updated on the Outage.
