What is the CrowdStrike tutorial about, the antivirus that paralyzed the economy?
Today I will try to explain to you what caused the failure of computer systems in many countries, in airports, banks, shops, hospitals, etc.
What is CrowdStrike?
CrowdStrike is a cloud-based security solution that deals with behavior-based analysis of services, files, applications on computers.
This is a security solution addressed to the enterprise environment, i.e. private or state companies
CrowdStrike is like a kind of more sophisticated antivirus for companies.
What caused computers to crash around the world?
We must mention from the beginning that this CrowsdStrike affected Windows operating systems, which were operational in airports, banks, shops, offices, etc
What happened?
Following an update released by the CrowdStrike developers, for Windows, all computers running this Agent (CrowdStrike) got stuck in a restart loop (boot loop)
Virtually all Windows computers that had CrowdStrike rendered useless.
Why wasn't the problem fixed quickly?
Unfortunately, the problem is that these computers that got stuck could no longer receive updates, and the problem could only be solved by the manual intervention of a technician.
Solving
There is a workaround, but it's taking a long time to get all the affected computers back on their feet.
There are approximately 8,5 million computers affected, and each of them needs the manual intervention of an IT-ist
The solution consists in manual intervention, booting the affected computer in safe mode and deleting a file
Simple users are not affected
CrowdStrike, being an enterprise security solution, PCs of ordinary users are not affected.
However, people around the world were affected by airport waits, delays in goods deliveries, etc.
