A massive IT failure caused by a faulty update from cybersecurity firm Crowdstrike has disrupted millions of computers worldwide, affecting various sectors including airlines, hospitals, and supermarkets.

The update, which targeted Microsoft systems, led to significant operational halts, with reports indicating that around 8.5 million Windows devices were impacted.

Flights were canceled, surgeries postponed, and many businesses faced shutdowns due to malfunctioning cash registers.

Crowdstrike has acknowledged the issue and is working on solutions, but the full extent of the damage and potential insurance claims is still unclear.

Experts warn that the incident could lead to substantial financial losses, potentially in the billions, as companies assess the fallout from this unprecedented cyber event.
