AMD chip flaw

Did you read the comments? Something seems weird with all of it.
Very possible. Too early to tell.
-
the comments are definitely all very fishy.
-
This looks fake.
Zero technical details on the website or whitepaper.
The website is new.
The CFO is a hedge fund manager. -

Very glad to see CTS not going by the 90 day "cover up" window so many so-called research firms do. That part is good, for sure.
Not sure why you see it this way. If an exploit or vulnerability is discovered, yet is probably getting little to zero traffic at the time, why disclose it publicly immediately before allowing the vendor/manufacturer to research the issue and patch. Otherwise, you run the risk of a lot more people trying to exploit this in the meantime. And I'm not specifically referring to this issue because I don't know much about the risks involved, I'm just speaking generally here.
But yes this does all look suspicious. Some short-selling firms involved trying to make a buck it looks like. Paid for by Intel??

Because I believe that security information should never, ever be kept from the people who are vulnerable. The vendor should not get "special secret information" that their customers are insecure. Sharing that information with anyone that isn't the customers should be illegal.
Imagine if your house's locks and security system were discovered by researchers to have vulnerabilities that with a special knock would let anyone just waltz into your house undetected, anytime that they wanted to.
Now imagine that instead of telling you, the home owner, that this was true, they secretly told it to third parties that you may or may not trust, and may or may not know, instead of you? Now someone, who isn't you, and isn't the researcher has been brought in on something that can be used illegally, but secretly, against you.
Would you be happy to find out that third parties are conspiring about YOUR security?

That bit is an unknown. We have to assume that if one researcher has found something, others might have, too. We can never make the assumption that it is not already a broadly known and used exploit.
If a researcher was a true white hat, they'd always be looking to warn the victims, not third parties that have a reputation to defend.
The current trend of telling vendors, not victims, is about "big business' reputations are more important ideologically than customer's safety."
-
the core of there argument is ASmedia controllers, which AMD uses.
they state they have backdoors, but still no real demos on it, especially since asmedia is being used also on intel, and I reckon BIOS update can deal with them.

In this scenario, I wouldn't want them sharing this info with just anyone or third parties, but I wouldn't have a problem with them disclosing it to the manufacturer or those necessary to resolve the issue with time to fix before the public is notified. What good would notifying me do if I'm not equipped to fix it? All this does is make me stress while the "bad guys" learn how to easily bypass this mechanism. What few, maybe no bad guys were aware of beforehand is now made fully aware and can be used against me until fixed.

You keep mentioning third parties here, and I agree about that, but I'm talking about the manufacturers. If AMD has a chip flaw, I don't believe Facebook should be made aware much, if at all, before me, but I have no problem with AMD and whoever AMD employs to resolve the issue is aware 90-180 days prior to my knowing. I have zero skills to fix this issue myself, therefore I'm relying on AMD to solve the problem before others can exploit it.
You are correct we do not know the amount of activity going on prior to these types of disclosures, but I feel pretty confident that once these vulnerabilities are disclosed, traffic significantly increases because now EVERYONE knows. Unless there's something significant that I can do as a workaround in the meantime, I just assume keep it private until the issue is resolved or the company is unwilling to resolve the issue in a timely manner and needs public shaming.

And there it goes, but I will still use AMD products.

The manufacturers are a third party. The flaw exists in systems owned by customers. The flaws at the manufacturer are minor, the flaws at the customer are the concern.
It's like finding out that Ford has cars without the breaks working, and warning Ford and giving them time to fix the breaks before you warn drivers that they might kill their families.
Once the sale is made, the owner with the moral obligation to be warned is the customer and the manufacturer is out of the picture.

That's not true. You have the skills to find an alternative vendor, to protect yourself against exposure, to shut off systems, etc.

Yes, but once announced, customers can protect themselves.
The question is... how long do we protect the guilty before we inform the innocent? If there is one party with a right to know, it is the innocent consumer. There is an ethical obligation there. Sure, as the researcher, you are beholden to no one and can just sell it to any criminal organization you want. But as the vendor, if they know for one moment and don't tell their customers, they should be held accountable as if they were any other malware vendor caught red handed.
Obscurity is never security.

All these situations look weird. Have anyone seen the official AMD response?

I wonder if these guys were trying to pick up stock really cheap or something. Although Intel wasnt really affected too much with Meltdown/Spectre
