Not sure who needs to know this, but if you download and install the Windows version of Rufus, the free software for writing ISO images to USB/CD-ROM, your PC will end up with about 100 trojans.

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 extremely rare secure boot W?

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.
However, in my defense Google's default search results list rufus[.]ie as the authoritative site

@briankrebs The official one downloaded via https://github.com/pbatard/rufus or https://rufus.ie? 🤨
@sindarina @briankrebs did you notice that the GitHub repo links to rufus.ie?

What chance do I have, if you get hit? -

@briankrebs I bookmarked it a while back because the search results were always such a crapshoot
@briankrebs ‘rufus.ie’ IS the official website, by the way, linked from the GitHub and such. Did that get compromised?

@briankrebs huh, that is the traditional official domain for it, isn't it?
-
@sindarina @briankrebs did you notice that the GitHub repo links to rufus.ie?
@ajn142 @briankrebs Yeah, it is the official website? Or used to be, at least?

@briankrebs the link the to official site from the GitHub page also links to Rufus.ie so something ain’t right

@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 You're absolutely right. It's like the flashlight app. Duh. Should be included so people don't search for it and install malware.
-
@briankrebs the link the to official site from the GitHub page also links to Rufus.ie so something ain’t right
@cienmilojos @briankrebs The download links on the site also link back to GitHub. Wikipedia shows it as the official site too.

@sindarina @briankrebs somebody with a malware lab should try pulling both the rufus.ie and GitHub versions and see if the hashes match, since .ie doesn't provide hashes.

@briankrebs I wonder if they have updated PHP…

@sindarina @briankrebs next question would be what components it downloads, and did one of them get poisoned in a supply chain attack.

@ajn142 @briankrebs The .ie links straight to the GitHub download, though. And as far as I can tell the checksum matches.

@ajn142 @briankrebs Also, if the portable version, which shouldn’t download anything at all, does the same thing.
