A global cybercrisis produced by Microsoft's Cloud services.

On Friday, July 19, 2024, there was a global cyber crisis that affected a wide range of industries, including aviation, media, financial institutions, banks, government institutions, telecommunications companies plus many other industries. Nor the Olympic Games in Paris

Without a doubt, this is the biggest worldwide crisis generated by an IT problem, occurring on operating systems Windows, and the damages are very difficult to estimate. Airlines in the United States, Asia, Australia and Europe have canceled their flights, media companies are left with their computers and platforms blocked, government institutions where many systems are no longer functional, hospitals, factories and many other industries.

Why did this global cyber crisis occur?

Following a security update by Crowdstrike for Microsoft, terminals with operating systems Windows they started showing "Blue Screen of Death", being unusable.

At the root of the problem is the blocking of Microsoft's Cloud servers, which are used on a global scale by numerous companies and institutions. Basically, global systems that are interconnected and use Microsoft services, have broken applications and platforms. For example, at airports, airlines can no longer scan boarding tickets and can no longer do online check-in due to blocked servers. Also, many applications based on Microsoft's Cloud services are no longer functional.

Millions of users Windows around the world are experiencing the Blue Screen of Death (BSOD) error, which causes the system to shut down or reboot suddenly. Microsoft said in a message that the error is caused by a recent update to CrowdStrike.

Apparently, this issue in the Crowdstrike update spawned others across multiple Microsoft services. There are many customers experiencing issues with multiple Azure services in the Central US and Europe region while Microsoft investigates an issue affecting various applications and services Microsoft 365.

CrowdStrike CEO George Kurtz said the IT issue that caused the global outage has been identified and a fix has been implemented.

Kurtz said the cybersecurity company is working with "customers affected by a flaw found in a single content update to Windows” and that the issue “is not a security incident or cyber attack.”

Here is the full statement:

“CrowdStrike is actively working with customers affected by a flaw found in a single content update for hosts Windows. hosts Mac and Linux are not affected. This is not a security incident or cyber attack.

"The problem was identified, isolated and a solution was implemented.

“We recommend that customers access the support portal for the latest updates and we will continue to provide full and continuous updates on our website. We also recommend that organizations ensure they communicate with CrowdStrike representatives through official channels. Our team is fully engaged to ensure the security and stability of CrowdStrike customers.”

Even if at the moment this global cyber crisis is being solved by CrowdStrike and Microsoft, it will certainly have consequences in terms of development strategies and architecture of interconnected IT systems that depend on a single provider. In the past, companies such as Meta, Google or Cloudflare had problems with the operation of services, which affected companies all over the world.

In conclusion, a update security breach caused the largest cyber breach in history. Microsoft said it has fixed the root cause of this global outage, but the effects of the cybersecurity outage continue to affect some apps and services Office 365 worldwide.

"Although the initial problem has been resolved, users may still face difficulties in using some of the platform's functionalities. The company is working to fully restore all affected services," Microsoft said in a statement.
