How to avoid CPU backdoors?

no, at least not until you somehow got your hands on secret information about the hardware. it can be done to some extend with reverse engineering and then you - maybe - can flash something like coreboot as replacement but....

chances that you cannot install windows and play games then are pretty high.

Most CPU backdoors like the Intel ME will halt the system or otherwise prevent booting if it detects the code is disabled or tampered with.

You stop posting and lurking on Jow Forums and letting them feed your paranoia

Don't confuse this with >nuffn 2 hide
It is just that it doesn't matter, if you were doing something that needed security you wouldn't be on x86 (or a computer honestly)

Short of entirely engineering your own computing systems with your own hardware of your own fabrication, you don't.

I am thinking about getting such a motherboard and CPU and building a nice computer, but then again, what OS would I use? Debian?

Networking isn't anything specific to UEFI. Legacy BIOS also had networking for things like PXE booting. Yes, UEFI can have a more full-featured networking stack, but not all OEMs include it in the build since there isn't much out there in the consumer market that uses it. The argument about there being backdoors in the network stack can be made for any proprietary software, and isn't anything specific to UEFI.

What people really need to be worried about is the ME. That shit's fucked.

it's a nice wholesome multi level aproach to backdoor computers. why only look at one of those fuckers?

What's "ME"?

the voice inside your head

The Intel Management Engine. A 2nd processor located in the Platform Controller Hub (PCH) that has complete access to all of RAM and every peripheral on the system. Basically the NSA's wet dream.

I don't fear the NSA, I fear lazy faggots who will not update their software (my UEFI) for years despite known vulnerabilities, which happens ALL THE TIME in corporate world.

I don't fear them either, but I do think it's wrong to allow that sort of thing to continue, if nothing else just on the principle of it. Totally agree on your second point.

There's a few Ryzen motherboard that allow you to turn off PSP, which is the Amd version of Intel ME aka hardware backdoor. I believe Asrock ones have that option on the latest bios updates.

you can't

still runs extremely complicated and vulnerable proprietary firmware pre-boot

buy amd

Also
>Ir's fucking loud

If there is a hardware access to system, they have to send that information to somewhere, is there a way to block that communication? something like adblocker or pihole or something to manufacturer sites?

Most likely windows then, botnet central

you're a dumb fuck. CPUs with backdoors are forever compromised, as long as a backdoor exists nothing but time can stop others from exploiting it, and then they have complete control of your information.
Hell even with specter now you could have it in your pc and when you will type your credit card information into amazon its going to some random russian whos gonna use it for child porn and then you get in trouble for it, but you deserve it since you are so dumb

No. Well, in theory you could use external networking monitoring and block anything suspicious but

1. hardware backdoors in monitoring hardware
2. backdoors in soc firmware
3. backdoors is os/drivers
4. backdoors in applications (or simply bugs)

your microphone or webcam could livestream you right now over the internet and neither your computer not network router show any hint there is traffic happing.

Are Librem computers the only way to get non-backdoored hardware, then? Besides getting all the equipment and raw materials and making some yourself, of course.

No because they don't run Libreboot and contains proprietary software blobs
Get a thinkpad

I'm using Windows XP and Pentium 4, good luck with your botnet shit :^>

Only way really is to buy an AMD FX-8370 or FX-9590 paired with a Gigabyte Mobo which were the last with BIOS.

No.

Poorfag.

t. seething botnet

>YOU HAVE NOTHING TO HIDE, SECURITY IS MEME

Yeah, that's nice and all, until Intel accidentally saves my private information in a notebook file and forgets to encrypt it, letting every russian in Putin-land have free roam of my passwords and secure information.

>have to use outdated, under performing, and/or unsupported hardware
fucking why
don't need full libre just want to be safe from most things

Don't use cpu, it's easy.

Please.

Try finding a new or second hand 990fx motherboard for a decent price. Most are more expensive than your latest high end Intel housefire boards.

Running on nehalem did not need more.

Edit found one: GIGABYTE GA-990FXA-UD3 - Socket AM3+ - Chipset AMD 990FX - ATX @ 149€

Not cheap for a 7 year old board...... also the UD7 is the high end variant

who cares about IT antiques ? Garbage build in China
