Linux computer vendor System76 announced this week that it will roll out a firmware update to disable Intel Management Engine on laptops sold in the past few years. Purism will also disable Intel Management Engine on computers it sells moving forward. Those two computer companies are pretty small players in the multi-billion dollar PC industry. …
... Intel's Management Engine is a hardware and software system designed to provide some remote management features. But it's come under criticism from privacy advocates, security researchers, and the free and open source software community.
That's because Intel Management Engine is basically a mystery. It's software that runs independently of a computer's operating system, which means that even if you wipe the OS, the Management Engine is still there. And there's no good way to know what it's doing.
The risks aren't just theoretical – Intel recently acknowledged a security vulnerability affecting nearly every PC that shipped with a 6th, 7th, or 8th-gen Intel Core processor. While the company is working with PC makers to roll out updates to patch that vulnerability, it wouldn't even exist if Intel hadn't bundled a feature many users don't need and won't use with its latest chips.
System76 are making a similar move:
System76 is one a handful of companies that sells computers that run Linux software out of the box. But like most PCs that have shipped with Intel’s Core processors in the past few years, System76 laptops include Intel’s Management Engine firmware. Intel recently confirmed a major security vulnerability affecting those chips and it’s working with …

System 7.6 was riddled with Bomb errors which would crash the entire OS constantly. I had the misfortune of running System 7.6 on a PowerBook and I needed to run Disk First Aid every day and Norton Disk Doctor every week to reverse corruption caused by all the crashes. I even installed a keylogger on my own laptop as a failsafe against losing unsaved work.

This is a good first step: an official acknowledgment that there is a problem.
But... disabled is not gone. And if it is disabled with "a firmware update" then that means it is really just a software adjustment, not a physical on-off switch that can't be ignored by malicious code.
What one update can disable, the next update can re-enable. And the next "update" might be attached to that phishing Spam.

You're misinformed. The software being disabled can't be rewritten from within the operating system, barring bugs. Disabling every bit of it that takes outside input goes a long, long way towards making it impossible to alter it again without physical access to the machine and special hardware.

Let me take what at least amounts to a semi-educated guess as to how it is disabled. They're flashing the BIOS. That is generally how all firmwares have been updated. You have to boot to something - Windows or DrDos or something - and initiate a flash sequence. It would be rather hard to disguise a flash. I'm sure it can be done, but at some point, a savvy user should realize that something unusual is happening. Until informed otherwise, I'll presume that few if any of us are going to click through a malware bios installation. But, the unwashed masses? Yeah, I can see that happening.

Actually, re-flashing can easily be done silently in the background. It's just that vendors are much too lazy to update their flasher to anything newer than DOS.
All that is actually necessary is the right pattern of reads and writes to the flash chip. In Windows, that requires kernel level access, so a hacked driver will be involved, but if you can get admin level access, you're in, and even after the system is "cleaned up", you're still in.

It can be done through a USB device (not through the OS, the USB device is essentially a JTAG programmer exploiting a bug in the existing firmware) or via physically clipping on to the chip to program it.
Not faith, really. Disable the bits that are being disabled and it's stuck with some very narrow attack surfaces that it's genuinely possible there actually are no exploitable bugs in.

That is, as far as we know, needed to modify the firmware without having the signing key. If you have the signing key, you can just flash the BIOS to load the signed image on boot. Presumably, you can load the already signed official firmware with the known security flaws without having the signing key.
For all we know, the signing key has already leaked. Considering how tight lipped Intel has been, I doubt they'd tell us about such a leak even if they knew.
Meanwhile, didn't Intel claim the chipset couldn't boot with the ME disabled at one time?

You're right, of course, but for the moment disabling is the only option.
However, having a big manufacturer like Dell disabling the engine is a huge pile of egg in Intel's face. Add in the undoubtedly exciting reactions from customers like the government, and many large businesses, and it is possible that Intel will rethink the whole concept. Offer the ME only to people who actually want it. Even better, of course, would be to eliminate it entirely. Wake-on-LAN and similar functions could be handled with relative simple hardware - there's just no need to have an entire operating system running in there.
Why Intel ever thought this was a good idea? Frankly, it reminds me of the VW emissions scandal. "No one will ever notice, if we just stay quiet" becomes "No one will find any security holes, if we never publish the code". Stupid, really.
Meanwhile, I'm sure the ME is now under attack by zillions of hackers. How long until they find the backdoor the government asked Intel to install? Odd are good that there is one...

Well, Frank, it reminds me of Intel's own decision, years ago, to force every Intel chip to identify itself with a unique identifier in all communications with the outside world. https://www.wired.com/2000/04/intel-nixes-chip-tracking-id/ [wired.com] Despite any claims to the contrary, that identifier was ideal for regimes wanting to squash dissidents, fascist corporations wanting to kill piracy, or even stalkers slurping data on their victims. Imagine, every forum such as this, forced to query your intel identifier, and to post that identifier as part of your user name. Instead of Bradley13, you might be BradleyATPO490B715Q99 because that identity was supplied by your CPU when you registered. Given the opportunity, there are government agencies who would be happy to mandate that everyone is identified in such a manner. Goodbye anonymity!

That CPUID was simply replaced by motherboard bios serials, hard drive serials, memory dimm serials, video card serial ids, and ethernet mac addresses?
After people won on the CPUID front nobody made enough of a ruckus, and even *IF* the cpu doesn't have a hidden cpuid instruction still operating within it somewhere for government types to interrogate, every other facet of the system does. And if they can get one of those, nevermind 3 of them, they can identify pretty much every person using a computer unless *ALL* computer purchases were used and made with cash.
I've had this concern for a number of years and it was one of the secondary reasons I quite playing MMOs. Any application with root or administrator level access can poll both the DMI information block (mobo, memory, and sometimes hdd serials) from the bios, as well as the AMD/Nvidia GUID, as well as the network hardware address (which may even be available to unprivileged users on many systems, such as linux and windows, read-only even as an unprivileged user!) Any one of these can determine the original OEM owner of the device if they paid with a credit card, or went to a store, like fry's or microcenter, that requires your name/phone number when ordering a behind the counter item, which cpu, memory, motherboard, video card and hard disks may be, depending on store and pricing. Excluding of course loss prevention videofeeds that could easily be (if they are not already) sent to the FBI/NSA for facial recognition along with purchasing records. Facial recognition may not be that accurate by itself, but if you combine it with nearby matches and a database of 'verified' hits along with historical drivers license/passport photos and any time a person purchased using credit card, or with identifying information tied via in store sales desk purchases, you can quickly narrow it down to real hits and tie the hardware to them.
This doesn't stop criminals/used hardware purchasers from staying under the radar, but it helps keep track of the sheeple who are usually considered the far bigger 'actual' threat, since there aren't enough criminals to rebel against the system, but if the plebs ever start, then having a historical record of their hardware so you can either falsify or more than likely find something legitimate to prosecute them over which can all be tied together with their hardware serial numbers and in-store video feeds.
