How to hack a turned-off computer, or running unsigned code in Intel ME
In case you haven't already used the following, please note that the NSA had an undocumented "backdoor" included which "disables" the ME. (Man, oh man, I wish I was making this stuff up.)<p><a href="http://blog.ptsecurity.com/2017/08/disabling-intel-me.html" rel="nofollow">http://blog.ptsecurity.com/2017/08/disabling-intel-me.html</a><p>I put quotes around "disables" because the ME is not fully disabled. The blog's analysis does show how it is in a "safe" state, i.e. forced to ignore the outside world very early in its code path. Also, not likely to brick your computer, assuming unscrewing your case and using a SPI flash programmer hasn't already bricked your computer.<p>Edit: "backdoor" in quotes too.
