Earlier today, machines and platforms for essential services around the world, including banking apps, were rendered useless due to a faulty Windows update that caused a major glitch in CrowdStrike software.
One of the world's leading cybersecurity programs, CrowdStrike is used by over 500 major companies including airlines, banks, major retailers, tech companies, and the U.S. government.
It's now considered the "largest IT outage in history," as Microsoft expert Troy Hunt stated.
Crowdstrike CEO George Kurtz announced earlier today that the company is actively working with both its customers and Microsoft to find a solution.
CrowdStrike is actively working with customers impacted by a defect found in a single content update for Windows hosts. Mac and Linux hosts are not impacted. This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed. We…

The source of the outage was found to be CrowdStrike's Falcon platform, a multi-solution program that possesses virus protection and real-time monitoring capabilities to prevent company systems from being hacked.
Businesses worldwide received the dreaded Blue Screen of Death (BSOD) when attempting to boot PCs used to manage vital infrastructure.
Australia was the first country to report the issue, causing havoc in airlines, banks, and TV operators.
Major European airlines such as Ryanair also reported the same issues.
Delta, United, and American Airlines are also experiencing communications blackouts, according to The Federal Aviation Administration (FAA).
This reminds us about the interdependencies our civilisation built. Critical systems assume that many trusted software simply works. Something goes off and many systems go down. Millions of losses, loss of time, perhaps health (Emergency call systems down), etc.

Due to the extreme nature of the blackout, industry experts, like independent cybersecurity consultant Lukasz Olejnik, have projected losses of millions of dollars and man-hours.
Many emergency centers were affected as well.
911 hotline centers in Alaska reported malfunctions in system infrastructure for several hours, prompting the Alaska State Troopers to temporarily redirect citizens to different phone numbers.
According to CrowdStrike, the company has already deployed an update to fix major problems.
However, many companies are still reporting software issues.
Not a Breach, Just an Error
CEO George Kurtz's latest announcement carried a bit of good news.
According to him, the blackout was not caused by a security breach.
The company also quickly came out with manual instructions that organizations could follow to repair the problem on affected PCs.
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…
As major companies scramble to regain their bearings, the blackout has revealed the many cons of industry reliance on centralized technology.
Tech giants Meta, Google, and Tesla have also had to cope with revenue and client loss over major software glitches, remedying the situation by giving credits and recalling products.
Companies can circumvent these consequences by always having backup systems ready in case of tech service disruptions and ensuring that their tech infrastructure is maintained and updated regularly by trusted companies or professionals.
