HOW A SOFTWARE UPDATE FROM CYBER FIRM CROWDSTRIKE CAUSED ONE OF THE WORLD'S BIGGEST IT BLACKOUTS

Summary from the TLDR newsletter

A fault with an update issued by CrowdStrike led to worldwide outages on Friday. CrowdStrike is a cybersecurity vendor that develops software to help companies detect and block hacks. It uses cloud technology to apply cyber protections to internet connected devices. The software requires deep access to systems to scan for threats. A fix has been issued, but it could be hard to implement - engineers will have to go into each individual data center running Windows to apply the fix, entering complex encryption keys manually for encrypted machines.
