CrowdStrike is a prominent cybersecurity company specializing in protecting computer systems from cyber attacks. One of its key products is the Falcon Sensor, an advanced software tool designed to monitor and prevent malicious activities on computers.

The current issue caused by the Falcon Sensor update has triggered these errors, leading to system crashes and disruptions for numerous users.
How Widespread is This Issue?
The impact of the faulty Falcon Sensor update is extensive due to the widespread use of CrowdStrike's software. Affected platforms include major services such as Amazon Web Services, Microsoft 365, Azure, Instagram, eBay, Visa, and AT&T. Users can check the status of various services on Downdetector, a platform tracking service outages.
The problems have had far-reaching consequences, including:
