Does anyone here know someone who works on these various management engines? It'd be interesting to see if the security services were involved or if they really were back dooring all computers right?

My guess is it's definitely possible but it would have been popped by foreign agencies by now too and there would have been a leak of tools to exploit such devices? I guess maybe it's very tempting to be able to hack any device though so knowing the NSA they are probably for doing this, fuck the consequences?
