From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This isn't a gloat post. In fact, I was completely oblivious to this massive outage until I tried to check my bank balance and it wouldn't log in.

Apparently Visa Paywave, banks, some TV networks, EFTPOS, etc. have gone down. Flights have had to be cancelled as some airlines systems have also gone down. Gas stations and public transport systems inoperable. As well as numerous Windows systems and Microsoft services affected. (At least according to one of my local MSMs.)

Seems insane to me that one company's messed up update could cause so much global disruption and so many systems gone down :/ This is exactly why centralisation of services and large corporations gobbling up smaller companies and becoming behemoth services is so dangerous.

after reading all the comments I still have no idea what the hell crowdstrike is

Seems to be some sort of kernel-embedded threat detection system. Which is why it was able to easily fuck the OS. It was running in the most trusted space.

Company offering new-age antivirus solutions, which is to say that instead of being mostly signature-based, it tries to look at application behavior instead. If Word was exploited because some user opened not_a_virus_please_open.docx from their spam folder, Word might be exploited and end up running some malware that tries to encrypt the entire drive. It's supposed to sniff out that 1. Word normally opens and saves like one document at a time and 2. some unknown program is being overly active. And so it should stop that and ring some very loud alarm bells at the IT department.

Basically they doubled down on the heuristics-based detection and by that, they claim to be able to recognize and stop all kinds of new malware that they haven't seen yet. My experience is that they're always the outlier on the top-end of false positives in business AV tests (eg AV-Comparatives Q2 2024) and their advantage has mostly disappeared since every AV has implemented that kind of behavior-based detection nowadays.

AV, EDP they offer other solutions as well. I think their main selling point is tamper-proof protection as well.
