The update bug only affected 1% of all Windows users in the world, but the mess may take weeks to clean up.
The mess of Crowdstrike, which messed up millions of Windows devices, could take weeks to sort out.
This is what the information security experts assessed on Sunday. The issue was reported by, among others, a British newspaper Guardian.
More than 5,000 flights have been cancelled. The costs of the mess can rise to more than a billion dollars, said the American CNN.
Britain’s NHS, which was one of the worst affected, said on Sunday that its software still runs slowly.
Disruptions to air traffic are still expected for the beginning of the week in, for example, Britain and the United States.
The bug only affected 1% of Windows machines, but it caused a lot of chaos
The US security company Crowdstrike released an update to its security software on Thursday, which turned out to be faulty.
It crashed millions of Windows devices.
The result was serious problems around the world. Train traffic, banking services, large media websites and healthcare information systems were disrupted. Thousands of flights were cancelled.
According to software company Microsoft, the developer of Windows, the flaw affected 8.5 million Windows devices worldwide. It only corresponds to about one hundredth, or one percent, of all Windows devices.
Finland was spared the chaos because only large companies use the problematic Crowdstrike Falcon software. In addition, information security software from Withsecure (formerly F-Secure) is commonly used in Finland.
The matter is evaluated by Withsecure’s research director Mikko Hyppönen In an interview with on Friday.
Project manager of Aalto University’s Cyber Citizen project Marianne Lindroth emphasized to STT on Sunday that the error of one company does not affect the software of ordinary users and that security updates can be done normally.
Crowdstrike’s stock dropped immediately
Crowdstrike’s mistake may be the largest and most expensive data breach ever.
The company assured on Sunday that all the problems had been identified and patches sent to customers. Company founder and CEO George Kurtz apologized for the problems caused by the company.
Crowdstrike’s share price fell by almost 20 percent as a result of the incident. The rate is expected to fall further on Monday.
