Imagine millions of computers worldwide going down all at once—that’s exactly what happened on July 19, 2024, due to a critical error by a cybersecurity firm called CrowdStrike. Their faulty update malfunctioned, causing a blue screen of death on many Windows machines and rendering them unusable. This defective code in the CrowdStrike update affected numerous organizations that rely on it, including Microsft Windows, American Airlines, Mercedes, and the U.S. government. This outage caused the Microsoft Windows death screens, commonly known as Blue Screens of Death (BSOD), which impacted many companies worldwide by crashing their systems and losing unsaved data.
What is CrowdStrike?
CrowdStrike is a top-tier American cybersecurity technology company that provides cloud workload protection and endpoint security, threat intelligence, and cyberattack response services. CrowdStrike manages the security operations of over 29 thousand organizations, including some of the biggest and most notable, such as Alphabet’s Google, Microsoft, CISA, Panasonic, Amazon, eBay, and Intel. This is one of the most well-known companies in the security and has gained a good reputation since it investigated the Democratic National Committee hack performed by the Russian hacking groups Fancy Bear (APT28) and Cozy Bear (APT29).
What are the impacts on Microsoft?
Microsoft Windows, being a widely used operating system in both personal and corporate environments, was notably affected by the CrowdStrike outage.
Windows Blue Screen of Death (BSOD)
The biggest impact on Microsoft is the Windows blue screen of death, which results in affecting numerous IT departments of organizations, losing unsaved data, and infecting running processes. Here are the multiple sectors impacted by this outage:
1. Businesses
- Operational Downtime: Most businesses are now using technology for their projects. Windows is the most common product due to its compatibility with almost all software and applications. Companies store their business information in windows instead of writing it down on paper. Blue Screen of Death has a great impact on businesses because of the operational downtime; their data may be lost, corrupted, or even deleted. Any running operation may get stopped immediately by the occurrence of BSOD, which is quite affecting.
- Security Risks: Security risks increase as cyber defenses, antivirus software, and firewalls may be compromised during such disruptions.
2. Healthcare
- Patient Care: Windows-based systems are widely used in healthcare facilities for administrative tasks, diagnostic tools, and patient records. These types of outages affect these operations instantly and end up delaying medical processes and patient care. In the health sector, an outage can be very dangerous because of the emergencies in hospitals.
- Pharmaceuticals and Research: Pharmaceutical companies and research labs use Windows-based systems to store data. An outage can affect their research, including patient tests, which are urgently required sometimes.
3. Government and Public Services
- Administrative Functions: To store and analyze data, government organizations also use Microsoft Windows systems due to their compatibility and efficiency. From public records management to creating and managing documents, accessing documents, and managing databases, an outage like the Windows Blue Screen of Death can disrupt the running task.
- Emergency Services: As seen in the July 19 CrowdStrike outage, even emergency services like 911 can be affected. This is how Windows is crucial for federal-level organizations.
4. Education
- E-Learning Disruptions: Schools, colleges, universities, and other platforms use Windows for various tasks such as online classes, student records, teacher attendance, and fee records in accounts departments. BSOD can affect the learning process, affecting students and educators alike.
5. Transportation and logistics
- Flight and Train Services: Railways and airlines use Windows-based computers to manage operational logistics, tickets, and schedules. Outages like a crowd strike may cause major inconveniences for travelers, such as delays and cancellations, which is bothersome.
- Supply Chain Management: Logistics companies use Windows to manage inventory, schedule deliveries, and track shipments. Disruptions in the supply chain can cause delays that affect consumers and businesses all over the world.
Tips To Protect Yourself From Cyberattacks
How did CrowdStrike respond to the issue?
CEO George Kurtz publicly apologized and explained the reason behind this outage. CrowdStrike ensured, after recovering from the outage, that all the companies they are managing are completely safe now. According to their CEO, this all happened due to a small, faulty code, and it has nothing to do with any type of cyberattack. George Kurtz responded to the media controversies surrounding the hacking attack on CrowdStrike, ensuring their company was not hacked. After several hours after the attack, he said on a show that “we’re deeply sorry.”.
Conclusion
In other words, these types of attacks can cause a lot of damage to organizations, including data breaches, lost work, corrupted data, and interruptions to running operations. This incident not only highlighted the critical role cybersecurity companies play but also exposed the vulnerabilities in our digital infrastructure. The widespread effects of the Blue Screen of Death highlighted the need for strong and dependable cybersecurity measures in industries ranging from businesses and healthcare to government services and education.
