Microsoft estimates that 8.5 million computers globally were disabled by a recent IT outage, potentially marking it as the worst cyber event in history. The problem stemmed from a corrupted software update issued by security firm CrowdStrike.
David Weston, Microsoft’s VP, shared in a blog post that the affected devices make up less than 1% of all Windows machines but emphasized the severe economic and societal impacts due to CrowdStrike’s critical security role.
Microsoft, aiding in recovery efforts, stressed that the issue wasn’t related to their own software and underscored the necessity for rigorous quality checks on updates by companies like CrowdStrike. “This event highlights the need for safe deployment and disaster recovery mechanisms across the tech ecosystem,” Weston stated.
The incident could surpass previous major cyber events like the 2017 WannaCry attack and the NotPetya attack. It has sparked warnings from cybersecurity experts about an expected rise in hacking attempts. Agencies in the UK and Australia have advised vigilance against fake communications and websites.
CrowdStrike’s CEO George Kurtz urged users to interact only with official representatives. Secureworks researchers noted a surge in CrowdStrike-themed domain registrations by hackers aiming to deceive IT managers and the public. Cybersecurity agencies globally stressed sourcing information solely from CrowdStrike’s official site.
