CrowdStrike Update Failure Causes Global Outages and Chaos

A faulty software update from cybersecurity giant CrowdStrike has led to a massive global outage, affecting Windows computers and causing significant disruptions in various sectors such as businesses, airports, train stations, banks, broadcasters, and healthcare.

The issue originated from a defect in CrowdStrike's Falcon Sensor software, resulting in system crashes without fully loading. CrowdStrike has confirmed that the outage was not due to a cyberattack but a "defect" in the update. The company has since identified, isolated, and deployed a fix for the issue, although recovery may take some time due to the complexity involved.

CrowdStrike CEO George Kurtz apologized for the disruption and acknowledged that some systems might not recover automatically. The outage, which began late Thursday into Friday, was first noticed in Australia and quickly spread to Asia, Europe, and the United States. In a twitter post, he wrote;

Today was not a security or cyber incident. Our customers remain fully protected.

We understand the gravity of the situation and are deeply sorry for the inconvenience and disruption. We are working with all impacted customers to ensure that systems are back up and they can… — George Kurtz (@George_Kurtz) July 19, 2024

He also assured customers and partners that CrowdStrike continues to resolve this incident. He wrote;

As CrowdStrike continues to work with customers and partners to resolve this incident, our team has written a technical overview of today’s events. We will continue to update our findings as the investigation progresses. https://t.co/xIDlV7yKVh — George Kurtz (@George_Kurtz) July 20, 2024

The malfunctioning update caused Windows computers with Falcon installed to crash, resulting in the infamous "blue screen of death." Microsoft also experienced a significant outage in its Azure cloud region around the same time but confirmed it was unrelated to the CrowdStrike incident. Microsoft CEO Satya Nadella stated that the company is working closely with CrowdStrike to support affected customers. He wrote in a twitter post;

Yesterday, CrowdStrike released an update that began impacting IT systems globally. We are aware of this issue and are working closely with CrowdStrike and across the industry to provide customers technical guidance and support to safely bring their systems back online. — Satya Nadella (@satyanadella) July 19, 2024

CrowdStrike, founded in 2011, has become a leading cybersecurity provider, serving 29,000 corporate customers, including many Fortune 500 companies and U.S. state entities. The company's Falcon software is widely used to manage security on millions of computers globally.

The outage has impacted numerous devices, including cash registers, airport departure boards, school computers, and healthcare networks. The Federal Aviation Administration even issued a ground stop, grounding flights across the U.S. due to the disruption.

The U.S. government, including President Biden, has been briefed on the situation. Several federal agencies, such as the Department of Education and the Social Security Administration, have been affected, leading to office closures. The Department of Homeland Security is working with CrowdStrike, Microsoft, and other partners to address the issue and support remediation efforts.

CISA has warned of malicious actors exploiting the situation for phishing and other malicious activities. Organizations are advised to stay vigilant and verify the identities of individuals before taking sensitive actions.

For those affected, CrowdStrike has provided a workaround and a patch to fix the issue. The recovery process may require physical access to affected systems, which could pose challenges for companies with large numbers of computers or those located in different regions or countries.
