I honestly can’t imagine why someone would downvote that lol.

Sdio is exactly the kind of interface that one would use for hidden backdoors, since you need a very special piece of hardware to deliver the payload.

No one will ever discover that there are undocumented features that can be accessed by a nonstandard sdio device with just the right mis-timings… because the only thing ever going in that a lot is a memory card that is incapable of producing that signal.

At least until now lol.
