Huge Microsoft Outage Linked to CrowdStrike Takes Down Computers Around the World

 Huge Microsoft Outage Linked to CrowdStrike Takes Down Computers Around the World

A recent software update from CrowdStrike has caused significant global IT disruptions. The update, part of CrowdStrike's July 2024 Patch Tuesday, inadvertently affected IT systems worldwide, leading to outages in various sectors, including transportation and cloud services.

The impact was widespread, with notable issues reported in Microsoft Azure environments, resulting in delayed flights and other critical service disruptions

CrowdStrike is working to address the situation, and organizations affected are advised to follow their updates closely for remediation steps.

 

Banks, airports, TV stations, healthcare organizations, hotels, and numerous other businesses are experiencing widespread IT outages, grounding flights and causing major disruptions after Windows machines globally displayed errors.

Early Friday morning, companies in Australia running Microsoft's Windows operating system began reporting Blue Screens of Death (BSODs). Soon after, similar reports flooded in from the UK, India, Germany, the Netherlands, and the US. Notably, TV station Sky News went offline, and US airlines United, Delta, and American Airlines issued a “global ground stop” on all flights.

Hours after the issues started to emerge, CrowdStrike CEO George Kurtz issued a statement regarding the outages. He stated that the company identified a "defect" in a Windows update it had issued. "This is not a security incident or cyberattack," Kurtz emphasized. "The issue has been identified, isolated, and a fix has been deployed." Kurtz also confirmed that Mac and Linux hosts were not impacted and advised customers to refer to the support portal for further information.

A Microsoft spokesperson acknowledged the problems affecting Windows devices and indicated that a "resolution is forthcoming." Concurrently, Microsoft was dealing with an unrelated outage of its Azure cloud services.

These outages could lead to "millions" in losses for affected organizations that had to halt operations or business, according to independent cybersecurity consultant Lukasz Olejnik. Olejnik noted that the CrowdStrike update appears to be linked to its Falcon Sensor product, part of CrowdStrike's security tools designed to block attacks.

"This incident reminds us of our dependence on IT and software," Olejnik remarked. "When a system incorporates software from various vendors, it places trust in them, which can create a single point of failure—as seen here, where multiple firms are impacted.
