If I was a government intelligence agency I'd probably sell my soul to get access to these...

I get that they have legitimate use cases for corporations, but why are there virtually no consumer grade CPUs without that stuff ? Surely they would be less expensive and no one would miss the features on their home computers.

Didn't national treasure Edward Snowden prove this?

Well, there is this time a few months ago where the Chinese government hacked AT&T and Verizon using the mandatory backdoors the US government left for wiretaps...

That's the reason leaving backdoors is generally a really, really bad idea, because you don't know who else can use them

Yeah, we don't. It's generally hard/impossible to prove the nonexistence of something. Similar as with God. It's unlikely, but we can't prove he doesn't exist with certainty. These proofs only work for very simple and contained systems.

Wasn't that something Asange or Snowden blew the whistle on? That the CIA or NSA or something actually has backdoors in pretty much everything, along with all kinds of spyware floating around the net?

There's no way to check the whole thing, but you can totally pick a component and reverse engineer it, which is something people do quite a bit. When spying is found, it's usually a private company doing it.

The NSA doesn't care about your search history, but advertisers do. (and the government ever did, they'll just call up google)

I've worked for the government. They had me managing 78 full AWS accounts for various departments. Me, 1 guy. And I had to explain basics of tech to everybody in charge of the cloud accounts.

Our gov can barely manage itself, let alone some next level tech on millions of devices and keep track of it all. They couldn't even get me a new mouse without 2 forms, 1 online ticket, and 2 levels of approvals.

A few years ago they had rerouted shipments from Cisco to the NSA and then forward to the intended recipients. Not just a few parcels, but truckloads.

This is probably going to be a very unpopular opinion but I am much angrier at a corporation having my data than a govermment and the former is much easier to avoid

“If you can’t trust the governments of the world, then who can you trust?”

Okay so here's my take on it not that anybody asked.

There are likely back doors in all computerized Networked devices.

There is likely some identifying information being sent back to random servers from a myriad of places.

That being said, you are not worth the time to directly observe.

Most likely, all of this data goes into a large database where they analyze trends and look for people that are outside of various tolerance zones.

Other than that, all of your data is just noise, grist for the grist Mill.

It is only when you become a person of interest who is worth devoting the time to directly analyze that these risks escalate to the point where you should have concern about it.

99.9999% of us are just not important enough to pay attention to.

We will never have a way of knowing for sure. There are stories of government agencies famously requesting backdoor access to Apple devices, seemingly because they can't get in otherwise, and Apple refusing, however they end up getting access on their own eventually. But who knows how much of that is even true? Government agencies are historically manipulative when it comes to public narrative, so anything made public by them should be taken with a hefty grain of salt

We know they do, actually.

All US companies provide the NSA with backdoors. All modern AMD and Intel CPUs have the ability to run remote code signed by their manufacturer and snoop into memory.

Put the two things together and now you know.

We don't. The point is to reduce attack surface relative to target value. People use a VPN for piracy, for example, not because it's totally secure, but because rights holders generally aren't going to bother going after a single person when they'd have to go thru a VPN provider as well. OTOH someone doing it on clearnet is being logged by their ISP and the data is right there. OTOOH, the three letter agencies are absolutely going to bother if they have a tip that you're doing something really dangerous to the status quo.

TL;DR: It's like IRL security. If somebody really wants your shit, they'll find a way to get it. The point is to make it generally not worth it.

I mean we pretty much can be certain that we're all being surveilled to some extent all the time.

If the government wants to snoop, they can just get a Certificate Authority in the boat and MITM whoever they want.

In my region there are laws that telecoms have to provide a way to let the government snoop, but the government doesn't use it without probable cause.

Some people think a VPN will protect them, because the provider doesn't log, but all the government needs is the VPN keys and they can intercept all traffic between the VPN and the user and log it themselves.

It's difficult to know that for sure, which is why (e.g.) the US government wants to make sure that there is domestic chip manufacture with a completely controlled supply chain to make hardware for classified communications. It can help to consider the difference between targeted surveillance (spending millions to tap the President's phone, to get big juicy national secrets) and dragnet surveillance (tapping everybody's phone so that you can have dirt on Joe Schmoe if he does something interesting later, even if he is of no particular interest right now). Hardware backdoors would be used mostly for targeted surveillance.

Stuff like VPN's and encrypted apps can be of considerable help against dragnet surveillance, which is what the civil privacy community mostly cares about. If you think you might be a subject of targeted surveillance, you have to be much more paranoid. Not just hardware backdoors in your computer, but suspicious white vans on your street, microphones in your flower pots, FBI agents under your bed, the whole bit.

There are some countermeasures you can take against hardware backdoors (electromagnetically isolate a computer from the network and transfer data from it by floppy disc or similar) but basically you're in a different world if you're dealing with this.

You mght like the book "Security Engineering" by Ross Anderson (older editions free online and still very good: https://www.cl.cam.ac.uk/archive/rja14/book.html and scroll down). It goes into this stuff, has lots of good overviews even if you gloss over the technical parts, and will generally help you see clearly in the topic.

I would assume CIA has a list of vulnerabilities in processors /mobos that they can exploit

I wouldn't say stop intelligence agencies, but more like, slow them the fuck down. Because we know that they're going through tons and tons of paperwork to do it all legally as possible. So, it'll take them potentially years to construct a bit of a case to pursue whatever it is that they feel is worth their time to pursue someone over.

You have to operate as if they have back doors.

With that being said, shit positing is not a national security issue yet.

Although DHS chief glowie did provide comments recently on how online discourse is a serious threat to CEOs

So they are clearly monitoring all socials for these vibes.

The fact that they got full might of daddy Sam LARPing dead parasite is telling.

Shit Posting Might have more power than previously thought.

Even without copy cats, parasites will uncomfortable with this public sentiment.

But they never discuss why the pedons would feel sucn a way

The same way we know there's nothing wrong with drugs that are pushed en mass. We don't.
