From the perspective of USB device-born malware/exploits, especially affecting firmware (e.g., can an infected computer reprogram an inserted USB memory stick to act like a keyboard and autotype malicious scripts on another machine? Or flash the BIOS or hard drive firmware on that machine?).
Assuming I have multiple devices that all have USB ports but also all have SD card readers, is it safer (and how much safer?) to move files between the devices using an SD card instead of a USB memory stick?
Some devices are computers running windows, laptops running various flavours of linux in various locations. Ignoring electrical attacks as I would buy the USB memory stick / SD card new from amazon.
Does using an SD card in this way limit the potential threats to autorun executables? Does doing this prevent the computer from seeing the SD card as anything other than a storage device?
Thank you for wading through this poorly written question.
