Major CrowdStrike bug cripples Windows: Mac endpoints not affected


IT security company CrowdStrike on Friday… ConfirmedThat no macOS user is affected by the huge problems of its security software. So-called endpoint security software called Falcon Also available for Apple computers And is used by corporate customers. According to the company, it promises “industry-leading protection and response capabilities for macOS environments.” “Nullify malware and sophisticated attacks – even when you’re offline.”

The statement came before a bad day for Windows administrators and their users: a faulty Falcon update caused massive failures on Friday if popular security software was running on the computer. Airports, banks, supermarkets and countless offices around the world could no longer work or only partially. Temporary solutions now exist and machines are starting up again. But the industry will have to grapple with the incident for a long time, which could have been a cyber attack.

CrowdStrike further announced that Linux hosts will also not be affected. For Windows, the problem has been identified, isolated and a fix will be made available. Their team has been “fully mobilized”. The problem is that you can’t just roll out a patch because the machines won’t boot and it seems they are stuck in a “Blue Screen of Death” (BSOD). To get the computer to restart, a file must be deleted. It has the format C-00000291*.sys and the directory is in

to find. If this file has a timestamp of “05:27 UTC July 19, 2024” or later, it is already a modified version.

Endpoint security software is a more complex protection against malware and other data pests that integrates itself deeply into the system. This is also the case on Mac, even though it typically suffers fewer attacks than Windows. Falcon is available for both Intel and Apple Silicon Macs and aims to give administrators “unparalleled visibility” when monitoring their Apple computers. These include “thread intelligence” and the ability to mandate “IT hygiene”. It aims to warn against zero day, ransomware, and more complex attacks. Falcon can also control devices such as USB devices, and it also includes firewall management on Macs.

The fact that a small change causes massive disruptions has already happened at Apple, on a smaller scale than today. In 2020, a verification server for signatures under macOS failed, which prevented or significantly delayed the launch of apps. The solution was to disable internet access.
