This question already has an answer here:
Why or why not? As a corollary, I saw a presentation description in a recent CCC demonstrating the (non-hostile) use of micro SD cards as a cheap source of processing power. Does this render micro SD card fundamentally vulnerable, or potentially vulnerable, to the same type of attacks? Why or why not? Does it make them open to other forms of attacks? Why or why not? Are there other alternatives that are immune? Micro SD cards are nice because there are now SD card bays in most mobiles and workstations alike.
