What does trust even mean? Flash storage devices come with little cpus/controllers which run code the moment you plug in the device (note: nothing to do with mounting). If you can find a way to program them (many already have), you can exploit all kinds of OS bugs without even having a file-system on the device. There are just too many places to stash code in modern electronic devices for them to ever be considered 'trusted'.
- Hello71 13y agoThat's entirely irrelevant. It doesn't matter how the USB device gets its data; you could have a mainframe connected via USB OTG, and it wouldn't make one iota of a difference because USB does not have DMA.
- mschuster91 13y agoWhile the USB devices don't have DMA, the controller indeed has. And as the USB controllers are mostly the same anyways... find a bug in a common family and PROFIT.
