Major economic sectors around the world — including health care, transportation, emergency services and mass media — were hobbled today by an IT failure that caused a massive global outage of Microsoft Windows machines.
Why it matters: The scale of the issue is the latest example of the true reach of Big Tech and the growing risks posed by the widespread dependency on key systems.
Catch up quick: CrowdStrike, a cybersecurity company, pushed out a faulty software update to its flagship cloud-based service that provides antivirus monitoring and on-device protection.
- The defect caused Windows systems to crash and a full fix could take "days to weeks," Lukasz Olejnik, an independent cybersecurity researcher, tells The Verge.
The impact: All airline flights for United, Delta and American were grounded temporarily. Airports globally experienced technical issues and flight delays and cancellations.
- FedEx and UPS warned of potential delays as air cargo and ports saw disruption. DHL said the impact has been "very limited."
- JPMorgan Chase, Nomura Holdings, Bank of America and Haitong Securities were among the financial institutions that experienced issues.
What they're saying: "This is not a security incident or cyberattack," CrowdStrike said in a statement, adding that a fix has been deployed.
Zoom out: CrowdStrike is the biggest pure-play cyber company by annual revenue, WSJ notes.
- The company has been one of the top-performing software stocks in a year that's been otherwise rough on the sector. Shares of the company closed down 11% today, but are up over 93% over the last 12 months.
The rub: CrowdStrike says 60% of Fortune 500 companies and more than half of the Fortune 1,000 firms are clients.
- Its reach helps make it more effective at detecting attacks but also shows how one faulty update can "just as easily grind parts of the global economy to a halt," per WSJ.
What we're watching: CrowdStrike has not said how the product update passed its own internal reviews, Axios Codebook author Sam Sabin writes.
- Experts already anticipate this will be considered the largest IT outage in history.
