Key Findings

On July 18, 2024, a global Information Technology (IT) outage caused significant disruption to industries around the world, with thousands of Windows workstations and servers displaying a fatal system error message commonly referred to as the “blue screen of death.”
The incident reportedly impacts Windows hosts that have installed CrowdStrike’s Falcon Sensor service; it does not affect all Windows devices.
At the time of writing, the cause of the outage is not being treated as a cyberattack and is instead most likely to be a faulty or incorrectly deployed security update or a faulty channel file.
The outage is known to have affected Windows devices across the world, with a significant impact across multiple industries—including, but not limited to—Energy, Finance, Healthcare, Media, Retail, and Travel.
The current workaround provided by the vendor requires a physical presence at each device and almost certainly cannot be deployed remotely.
