CrowdStrike’s latest update to its Falcon Sensor software caused a major global tech outage on Friday due to inadequate quality checks.

The faulty update disrupted systems for banks, airlines, hospitals, and government offices using Microsoft Windows, leading to widespread crashes.

Security experts noted that the flawed code, which affected configuration or malware detection signatures, likely slipped through quality assurance.

The update’s rapid deployment without thorough testing contributed to the issue. CrowdStrike is working on fixes, but restoring affected systems will take time, CNBC has reported.

This incident highlights the risks of insufficient vetting in critical software updates.
