Why would you need proof that it has been backdoored? The fact that it can be backdoored should be enough to disregard it for all uses right from the start.

Trusting Trust says everything could be backdoored, but somehow I'm guessing you still use computers.

Interestingly, Trusting Trust style attacks on compilers was later (theoretically, idk to what degree it's been put into practice) solved by "diverse double compiling": https://dwheeler.com/trusting-trust/

If your threat model includes the nation state where you physical infrastructure is, you're hosed.

Literally hosed. There's a funny jargon term "rubber hose cryptography" that's used to refer to the cryptanalysis method where you beat someone with a rubber hose until they give you the key. It's 100% effective against all forms of cryptography including even post-quantum algorithms.

Hose-resistant cryptography is possible. Secret sharing comes to mind, or a system by which even the principals can only compromise a key slowly.

None of these are EUropean countries.

Scroll down and learn about FVEY+3 and friends.

Here's a link that starts down there:

Trusting Trust says everything could be backdoored, but somehow I'm guessing you still use computers.

If, for example, SHA2 had a backdoor or a weakness known only to the NSA, then random contractors (like Snowden) could use that to extract money from the Bitcoin network, which uses SHA256 as its core cryptographic primitive. That's easily a billion dollar motivation right there, and I can't imagine a bunch of low-paid government drones resisting that cash prize. Everyone has a price. Hence, there's a level of trust…

I'm not advocating in either direction here, but let's assume backdoors like this do exist: Just because they haven't been abused doesn't mean that they wont in the future.

Of the people I know that work with highly privileged materials, none would take advantage or abuse something like this, even with such a high payout. Even if they did, how would they continue to live comfortably? That said, it just takes one person under the right circumstances to act maliciously, which is why screening and compartmentalization is critically important for these organizations.

Nothing? I mean, you are already in US-based cloud, so if NSA is interested, they will just request information directly, no backdoors needed. (This is a good test for your security team, btw: if they say anything other that "we do nothing", you know its all security theater)

Very good point. That was the consensus from our team, so I think we're okay. Ironically, the data we're securing is because of US government requirements. So if the government wants to spy on itself, who are we to say?

The fact that this backdoor could leak and be used by a foreign government needs to be taken seriously.

Huawei stuff is proven to be compromised, just not by NSA, instead by China.

To my knowledge, no proof has actually been publicly presented for this claim. There have been a few stories that didn't pan out (like the one that boiled down to, "Huawei devices have telnet installed"), but no actual evidence of backdoors has come to light yet. This is despite the fact that Huawei has been under an extraordinary level of scrutiny for years. British intelligence was given extensive access to Huawei'…

Great post. Seeing similar with TikTok and DJI FUD

I'd usually agree, except when it comes to saying anything critical of China on the Internet, my statement is very true. The wumao is a real thing, and they're pervasive within online tech.

I wonder if you have enough self-awareness to notice why your behavior here might be considered bizarre. No, people who point out that your government routinely and brazenly backdoors equipment and software everyone uses (or rather, has forced upon them to use), while Chinese actions of this sort are evidenced to a lesser extent, and so the onus in justifying the use of that country's products is on the US at least as much as on China, are mostly not "wumao", nor whataboutists, nor anything of the sort. They're making an entirely sound argument an unbiased person would make given the context, you're just using those mind-killing political notions to dismiss a topic that offends your patriotic sensibilities.

Wumaos are low-paid grunts and sincere idiots who disingenuously downvote, report and post irrelevant nonsense regarding racist imperialist AmeriKKKa or legitimate Chinese clay/territorial waters/6000 years of peaceful history. This is very easy to see. You're free to suspect any interlocutor as being one, of course, but if that's your only retort, you'd do better not stooping to the level of an undeniable propagandist and instead conceding the object-level issue – or keeping silent.

Youtube would delist that before they could all see it though.

You know there are other ways to have a video and send it to people than YouTube, right? You can just email a link from dropbox or gdrive, or an attachment, or send a WhatsApp/Telegram/etc. message, send a letter with a USB drive, etc.

> You can just email a link from dropbox or gdrive, or an attachment, or send a WhatsApp/Telegram/etc. message

Why do you think governments are demanding those services give them access to quickly remove "misinformation"?

Isn't that just the US speaking in order to get more control? How is it proven? I've never seen any evidence of that, but there has been much evidence that the US does what they blames others of doing, like this and Cisco. At this point it seems the US is accusing others for doing bad things because that's what they themselves do. Huawei was growing really fast, threatening both Apple and Google. Then the US said it…

There is ample evidence of China's intentions and capability to install backdoors. Everything made in China or a heavily influenced Chinese country should be assumed to be compromised, even if 'proven' otherwise. Chances are we just haven't found the backdoor yet.

Sure - but all that is equally true of the US.

That doesn't prove anything. You're just saying that Huawei could theoretically be compromised, but the above commenter asked for evidence.

They are compromised in terms of governance, and their legal environment is the proof of this. Nobody has ever claimed that Huawei devices have backdoors. The issue is that the supply chain is compromised by legal means, not the hardware or software currently being shipped has technical vulnerabilities.

If you're using that non-standard definition of "compromised" then anything substantially made in the US, Australia, South Korea, Israel or Kazakhstan (non-exhaustive list) should be considered compromised.

I'd love it if people actually stuck to some principles and stopped buying from any of these countries. But using that legal situation as a reason to single out China/Huawei is bullshit.
