Solved M. Defender kicked ISO with Linux

[konradmakosa]

I have a suspicion, but I would like to get the opinion of the professionals. I have no experience of security and Linux myself (just the basics).
I am working on Windows 10, I downloaded the recommended version in an ISO file from the official site:

https://cdimage.kali.org/kali-2024.3/kali-linux-2024.3-installer-amd64.iso

I downloaded it to a USB stick using Rufus 4.6.
I have done this dozens of times with this and many other versions.
This time, however, Defender kicked in, identified one of the files as ransomware and blocked the network.
I'd swear an identical operation went off without a hitch a few months ago.
So why the sudden change?

Have i ever had this problem NO, mainly due to the fact i haven't used windows for over 20 yrs now,
Dose it surprise me, NO windows' security throws a wobbly on occasions especially after updates of which there have been far too many this year,
what file is it refusing to install.

ClamAV doesn't like Kali Linux either. I have to tell it to skip everything related to Metasploit when it scans or it will freak out. Even just mentioning some of the files that Metasploit uses will cause over 100 false positive results. Kali Linux includes a lot of tools that let a pentester break into a computer and Defender is merely doing its job. Don't sweat it. Just install the ISO. Make sure the SHA256 hash value matches up first.

By the way, I don't think any of us here are actually paid to be here.

On another note, I tried to go to the Debian Linux web site back when I started using an old laptop that was running Windows Vista and the web browser told me that the web site didn't even exist. Windows doesn't seem to like Linux all that much. Sure, you may be able to run a VM with a Linux guest OS, but it looks to me like nanosoft really doesn't like Linux.

The change is Defender is updated constantly. It really is nothing special. There's nothing conspiratorial against Kali. It's easier for MS to take the shotgun approach than the sniper approach when it comes to security. After all, Windows faces more security threats per month than most OSes faces per decade.
So long as you verify the signature and check the download link itself actually matches what's on the site (this was how the Mint community was attacked about 7-10 years back). If you're concerned, visit a recent snapshot on archive.org and check the signature there against what you downloaded.

Unfortunately, I can't tell you exactly what file it was, because the computer was immediately taken away by the Security Department

Thank you. That was my guess. After an update, Windows started to hate Linux even more...

The SHA256 sum is always checked, of course. Thanks!

Windows does not hate Linux....it is fearful of Linux because it is so damn good

Kali....that is a whole different matter. All things are possible where kali is concerned. I wish your security department luck.

Sounds more like a MS Defender problem since you are using Windows as your main os, not a Linux problem? I don't know how MS Defender works but maybe see if you can make en exclude for a specific file, other wise contact MS about your problem.

Install your Linux Distro...forget windoze and anti-virus software.
