I've been made aware of a post from someone representing Rufus who says I'm very confused about this post. I've reported that Windows Defender went bananas after I installed Rufus on a Windows 11 device. It immediately popped up warnings about hacktools and trojans being installed while it was installing. I wish I had a record of it but I nuked everything after the alerts.
@briankrebs Rufus doesn't have an installer though. That's the thing. One simply doesn't install Rufus.

I think it's worth noting, a long history of actors buying ad-space at the top of search engines.The url in the ad appears legitimate (it's visually the legitimate URL), but when clicked goes to a different url. I'm not positive that's the case here, but it's been done 100s of times for 100s of other tools (AI tool installers, chrome installs, etc), and there is zero visual indication it's an ad directing to the wrong domain.
Thanks to LLMs, the landing pages have also gotten much better at copying the real pages too.
Making it more difficult, is that ads don't always present themselves, so seeing it a 2nd time may take 100s of visits
Or maybe it really was a compromised rufus domain

Edit: The site I downloaded from was rufus[.]ie which is apparently the official site. During installation, the software threw up a couple of rather verbose messages saying it needed to download additional components.
Ha ha ha hah: you’re still using Windows. 🤪🤭
I recommend you self boost this one a bunch! LOL!

@briankrebs please be more specific, you're coming off like a rambling tech illiterate that complains that the PC is broken, and it turns out there is no internet connection. Did you check the checkum of the installer/exe? What ISO did you attempt to write? Can you name one single instance of malware included in the infection? -
A kind reader submitted the Rufus installer to any.run, a sandbox which walks through the installation of software to find malware that gets installed only *AFTER* the executable is clicked. You can see exactly all of the post-install prompts to download additional software that I also saw.
The main usage for Rufus in my mind is to image an iso of linux to a key - and then blow all those nasty microsoft malwares to smithereens!

@briankrebs So I hate to be snarky, but "dd" has been there all along people. Having to install an entire 3rd party application, for something that the OS should have stable, reliable methods for, to format a storage device and transfer a standard filesystem image to it, is intolerable. But it's Windows...depends on curl to download its own updates...

@jab01701mid@mastodon.social @briankrebs@infosec.exchange These days with WSL
ddis also available on Windows.@lispi314 @briankrebs I saw WSL and thought "why not just run linux or some other *nix variant". I even learned PowerShell, and it has lots of *nix like aliases and applets. I installed a Microsoft implementation of PS for linux because I did not want to actually boot Windows on my HW to write PS scripts for a Windows target I was being paid to develop.
Still - go native.

I remember reporting a vulnerability to the Rufus developer, and he was quite rude and condescending in response.@wdormann I just read the full thread, yes the full threat, and god what an insufferable attitude from this guy. I'm convinced he'd manage to disagree with the Pope on Catholicism. @xabean @briankrebs I

@briankrebs Here’s another user who faced malware alerts while using Rufus. They were flashing Kali Linux, though, and it’s ISO file got scanned along the process.

@rx13 @briankrebs this. I struggled to find the news article about it but yep, ad space being bought on common tools searches which show the correct website in the URL slot next to the result but take you to the non genuine page.

@briankrebs i'm sorry someone actually posted that on github issues?? Oy vey..

Is it ironic that your Windoze PC gets infected while trying to download a file that allows you to write an installable Linux ISO? I think very much so and I'm still LOLing about it.
@briankrebs you know you can run software in a vm and let it access specific devices while running? I trust very few software packages...

@briankrebs Yippi, I successfully infiltrated my workplace. Seriously though, sources, proofv, anything?

@briankrebs funny that it is possible to send the rufus installer to analysis when the rufus folks claim it has no installer.
The reality distortion field is strong here. -

Does seem to be quite a lot of look alike domains in the last week, so this is my best guess on your experience -
