junior infosec: how could you even consider plugging in an SD card you found on the ground, it could be malicious!

senior infosec: if they can root my macbook m3 from plugging in an SD card then they deserve to run whatever the hell they want

@0xabad1dea usb is easy to attack compared to sd (since usb can be a lot of different device types whereas sd can only be storage)

like orders of magnitude difference

@CauseOfBSOD the SD slot on a MacBook has DMA and afaik the USB doesn’t. The implied attack has already been shown to work.
@0xabad1dea WHY DOES IT HAVE DMA
@CauseOfBSOD block copy go brrrrr
