“We have obtained fully functional JTAG for Intel CSME via USB DCI”
At first it looks nice &quot;oh now we can get rid of it&quot; but it also opens up a very scary near future security-wise.<p>We&#x27;ve now entered a realm where an attacker could simply plug a device on an usb port of your computer for a few seconds to have it access your cpu&#x27;s ME through USB JTAG and take over it, allowing him to have full access and control over what you do&#x2F;read&#x2F;open&#x2F;type over the network, without you ever knowing it since you can&#x27;t see it. 
And the only way to get rid of it for sure would be to pretty much throw that cpu away and buy a new one.<p>Or am I being overly paranoid and there is something I haven&#x27;t considered that makes this scenario impossible ?<p>EDIT: given the answers I think my main concern wasn&#x27;t well expressed above. I&#x27;m not saying this as in &quot;ME is making it easier to be compromised&quot;. That may or may not be true, but that&#x27;s not my point.<p>My point is, we all know that once compromised, you can&#x27;t clean it and need to burn it all and start from scratch: recover from backup (not files on the compromised machine), format everything, reinstall.  
Due to the nature of the ME, this is not a solution here. The cleanup needs to be done at the hardware level. Unless I misunderstood something, once it happens, your cpu is done for, period.
And &#x27;using a hack to cleanup the hack&#x27; is still in the realm of cleaning up rather than start from scratch, it&#x27;s not a solution for the same reason than cleaning up your comprised linux box is not one and you need to start from scratch.
