Absolutely, but also everyone has known this since the early 2000s. Intel CPUs are completely and 100% compromised due to the NSA backdoor. They're also 100% completely compromised by poojeet script kiddies due to the meltdown and spectre vulnerabilities.

I hope that Intel guy bailed and got a job at AMD instead.

Let's assume that this is a real practice and that Intel is participating in on a large scale, through coercion or otherwise. Why wouldn't the US gov't also force AMD to do the same?

Good TLDR;

The ME is a separate CPU, so the ring terminology is kind of deceptive. In older versions, ME wasn't even an x86 core, it was ARC or something.

I think it used to physically be part of the chipset, but I'm not sure.

>> No.66642089

I don't think anything uses it, because it's mostly useless. Operating systems generally want to control access on a more fine-grained level than the hardware allows anyway, and therefore virtualizing I/O methods is more useful.
OS/2 reportedly did, in order to provide some user-mode processes with direct I/O access, but that just exemplifies why it's a bad idea, because the hardware can only grant or deny a ring total I/O access, whereas a reliable OS will rather want to grant I/O access to specific devices, if at all.

>Why wouldn't the US gov't also force AMD to do the same?
This isn't about "forcing". Theoretically, the Israeli government would be the ones doing the forcing, if anyone. It would be an excellent strategy to implement. Especially when you consider how much easier and cheaper this is, compared to constructing something like the system the NSA uses. Also consider the fact that the USA uses Israeli intelligence quite frequently. Remember the Kaspersky fiasco? Ever question how and why Israel was nosing around in their systems? Ever consider the fact that if their claims against Kaspersky were true, then that makes them also guilty of eavesdropping on classified information and probably for years.All of these Intel backdoors could have been shared with US agencies, too. There's just too many possibilities and opportunities for this shit to have not been taken advantage of.

It is absolutely possible, but noone knows whether it's actually true.

It's important to keep in mind that the IME backdoor that everyone knows and talks about is a different thing. That backdoor is in a known piece of IME functionality that is publicly known, only exists on certain motherboards, can be turned off, and is used for automated corporate management of computers. Using it, the IME actively fetches an IP address of its own (separate from the OS) in a non-hidden manner, and administrators can connect to it to manage the machine. The problem consisted in buggy authentication that allowed anyone to log in.

While what OP is talking about is certainly possible in theory, it has a number of special requirements, most importantly that the attacker has to be able to reach the machine he wants access to with network traffic in some way, which would be difficult since the IME doesn't have its own IP address. Even if it "hijacks" the host OS's IP address, it would still be perfectly visible to network monitoring if it tried to make outbound connections, which would certainly have been discovered had it been so. Contrariwise, since most computers are behind NATs, it wouldn't be possible for an external attacker to connect directly to the computer in question. That pretty much only leaves the possibility to embed hidden data in packets that are otherwise used for legitimate traffic, which in turn requires the attacker to either have direct access to a server that the victim is initiating traffic to (certainly theoretically possible in the case of Google, Facebook &c) or a MITM-attack on some router on the way. It's difficult to disprove that something like that might be happening, but if it is, then noone has publicly posted any information of just how it works.

Right, because fear of being persued, stalked,followed,whatever, for unknown reasons, is completely unnatural. It amazes me how many lunatics there are in this world. The lock industry is just a bunch of scam artists and snake oil salesman. Passwords? Give me a fucking break you paranoid fucks! As if a bunch of letters and numbers are going to save your ass! You dumbasses with guns are the absolute worst, though. There's nothing to fear,you're just crazy. You waste your money buying these things,when your tax dollars are already being spent to employ people armed with guns to protect you. There's nothing to fear at all.

Im not afraid of them you nigger. I just want them to respect my privacy. It's basic human decency. "Nothing to hide, nothing to fear" isnt a fallacy because of its assumption that you want to hide. Its a fallacy because it assumes that we are afraid. Im not afraid, and if a court of law granted a warrant to law enforcement to come search me I would allow them. But i have yet to receive such a warrant, so I'd hope that they'd mind their own business and spend my tax dollars on something more constructive.

In fact, the sole reason why your computer is capable of responding and turning on as you hit the power button is that it actually still is drawing (hopefully very minimal) power out of its power source.

The power button is not something like a light switch with two ways. It is a one-way switch that generates a unary signal, an interrupt for your hardware. This interrupt is only generated and then perceived by the controllers when the device is powered, and then cause your computer to turn on if it was "turned off".

Turned off state of a computer is merely a STAND-BY state with (hopefully) extremely low current draw being drawn.

I don't know anything in detail about a full-blown computer. I just took a hardware course where we dealt with microcontroller + FPGA units.
