00:00Microsoft has estimated that around 8.5 million computers around the world were affected by
00:07the recent global IT outage.
00:10The glitch was caused by a corrupted update issued by security company CrowdStrike, which
00:15caused computers running Windows to crash.
00:19That caused havoc across much of the world from Thursday into Friday, with flights unable
00:24to take off or land, some businesses unable to take card payments, and hospitals and clinics
00:29having to cancel operations.
00:32We've talked for a long time in the industry about the inherent fragility of foundational
00:37parts of the internet, these little bits of activity and infrastructure that underpin
00:42the whole thing and if they go wrong they can have really serious global consequences.
00:48The UK's National Cyber Security Centre warned people and businesses to be on the lookout
00:53for phishing attempts.
00:55And the German government's IT security agency warned that cybercriminals were trying to
01:00take advantage of the situation through fake websites and other online scams.
