The incident that led to a major failure of 8.5 computers was caused by a tiny update file that weighed around 40KB and was ignored by the company's error detection tools.
CrowdStrike Falcon is security software that is used on millions of Windows computers. Last Friday, the company released a small quick update for "collecting telemetry on possible new threat methods".
The problematic file was overlooked by Content Validator, whom the CrowdStrike trusted based on their experience, which eventually led to the infamous event.
