@jab01701mid @briankrebs ironically the official windows installer builder does support writing to USB directly but it doesn't have the customisation that Rufus offers for slipstreaming and deshittifying. But for other non-Windows ISOs? Yeah.
Though it should be noted that for awhile now a lot of images are designed such that if you mount them and copy their contents to the USB partition bare it'll work just fine and this can be done from stock Windows
@Lunaphied Okay. But how?

Look, compromises happen to everyone. I have received a ton of private messages asking if I'm okay. But the reality is that I stopped using Windoze a long time ago and this was a kind of one-off thing where I was trying to re-image an old system anyway (away from Windoze).

@briankrebs I wonder if @torproject should know because Rufus is recommended to those who wish to install Tails from Windows:

@briankrebs@infosec.exchange have you reported this on the rufus github repo?

@simon @briankrebs Please what Rufus version does it apply to? The last I've used is 4.9, and the only thing it asked to download was some Secure Boot-related pieces.

The cognoscenti don't use the term Windoze anymore - there is no need and it does age us somewhat!
Please tell us what you were attempting to install. We are all friends here and won't judge

I love all the commentary about how I'm supposedly inventing things here. Supply chain hacks or just selling one's site/brand happens. If you don't like the results too bad. Check them yourself.

@briankrebs tails.net has its own copy of rufus-portable.exe

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.
@briankrebs@infosec.exchange the scary boxes like, downloading from the MS github and checking for its own updates, which is opt in? what the hell even is this alarmist thread

@briankrebs you know you can create iso files from folders directly through PowerShell? I forget where I got the script from but it feels like magic every time I use it.

@StephenBoylett no, I didn't know that. If you can supply a link that would be helpful, thanks.

@briankrebs I feel extremely lucky considering I have two Windows workstations and one is for ML and Gaming so perfect patient zero situation which is why it's sharing a vlan with the other embarrassment, arguably worse: windows 10 set to danger-cart mode

No clue whether the resulting ISO is also malicious, but tried running it just for giggles on a spare Windows PC from bootup and the machine's bios said nope, wouldn't allow b/c security policy. Not sure if it's related but I've never seen that message before trying to boot up from a USB.
@briankrebs I only had that (the secure boot fail) problem if you click the skip windows login procedure. Or how ever its was called. (Last time i used it was years ago). then rufus modified the iso to skip the annoying install process which broke secure boot. Last time i used it without that option the image was valid with secure boot. and also never had any "want to download stuff" requests on my whitelist firewall. but may be outdated info. also i never used the installer only portable version. (it never tried any network-connection. nor did it spawn weird new processes/services.)
i'm pretty sure the "official" download was sourceforge at that time.

@briankrebs I'm not usually on Windows, but looking at my /Downloads I must have fetched and used it back in July, so I have this build.
I grabbed Malwarebytes (for want of something to do) and ran it before (clean) and with Rufus running (clean).
One thing I did note - I genuinely don't recall it fetching any additional files until you select an ISO, it reads it, and determines if it needs extra files which is mentioned on the page linked below.

@briankrebs I think I'll stick with dd.
