Two gentlement associated with a firm calling itself "Positive Technologies" have documented a manner for acquiring JTAG access to the "Intel Management Engine" on a machine running an 'Apollo Lake' family Intel Celeron (archived). Their recipe involves creating a special debug mode dongle of the sort used for opening up other consumer devices. This has been a very rough year for Intel's marketing wank.
The funniest bit is where the "security" circus clowns present the find as a "vulnerability" that "needs patching", rather than the reality, i.e. a successful anti-Fritz cure.
Something something lambs to slaughter…
Anyways, probably too early to call it a cure. Could just be a step towards one.
