The only actual "evidence" that was provided was a link to a falcon sandbox run, something which actually requires human analysis to draw conclusions about -- and anyone who has ever used it knows how many false positives it finds.
A better proclamation might be "cheap network adapter comes with an auto-running executable which needs further analysis".

I've seen so many correct responses downvoted and with horrible replies. Anyone who used old moderated email lists will see how culture changed and the decline of actual conversation. Even stack overflow has went downhill.

> An autorun.inf file is a text file that can be used by the Autorun and AutoPlay components of Microsoft Windows. When a USB drive is plugged into a USB port, an autorun USB dialog appears that prompts you to do certain operations: print images, run Windows Media Players, or open a folder. But what if you have a particular application on the USB drive and want it to be launched from the autorun USB dialog? You can put autorun.inf into the root of the USB drive and edit its commands to get the app started when the USB key is plugged.

No. Microsoft just said it will disable it. On some systems, i've seen it disabled (i don't know if by default or by AD policy) but, on the majority of Windows 10, it was not disabled.
