>All of the exploits require elevated administrator access, with MasterKey going as far as a BIOS reflash on top of that. CTS-Labs goes on the offensive however, stating that it ‘raises concerning questions regarding security practices, auditing, and quality controls at AMD’, as well as saying that the ‘vulnerabilities amount to complete disregard of fundamental security principles’. This is very strong wording indeed, and one might have expected that they might have waited for an official response.

Extremely fishy. 1-day notice? Such aggressive wording without even the chance for AMD to address the concerns?

Yeah it's suspicious. The website[1] has many fancy infographics, marketable names and fear mongering but you have to dig into the whitepaper[2] to find any details about the actual vulnerabilities. And even then it starts only on page 8 of 20 and you discover that it's vulnerabilities targeting the secure boot infrastructure and you need local admin to exploit them. It's not good but it's not a new Spectre or Meltdown.

If I was the tinfoil hat type I'd guess that Intel is trying to spread FUD but maybe it's just security researchers trying to generate a bit of buzz for their company at the expense of AMD.

It's possibly even more nefarious than that: 1) execute a series of puts on AMD, 2) release exploit 3) profit. If you execute an option with a far time horizon and give the company enough time to mitigate their vulns, then I think this is not an irresponsible thing to do (as it incentivises the company to actually do something), but with 24 hours notice...

Seeing as CTS-Lab's CFO also founded a hedge fund you're probably on the right track.

He is also the founder and Managing Director of NineWells Capital, a hedge fund that invests in public equities internationally. He holds a B.A. and M.A. from Yale University.

Basically a follow the money situation.

Could something like this be considered inside information? Or is it legal to actively manipulate stock prices to ones benefit in this way?

> Could something like this be considered inside information?

No, illegal insider trading refers to trading on inside information when you have a confidentiality agreement or a fiduciary duty. Information asymmetry is insufficient (or else it would be virtually impossible to profitably trade at all).

> Or is it legal to actively manipulate stock prices to ones benefit in this way?

The way you're presenting this is a false dichotomy. It's not "manipulating" stock prices except insofar as people broadcast news all the time which alters stock prices. Strictly speaking, it's not market manipulation if it's true. If it's false, it can be, which is why you really try not to do it unless it's true.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tyfon on Tuesday March 13, 2018 @02:12PM (#16578324)
Might the latter also depend on how you present it?

As far as I can see this is only an exploit of secure boot if you are already on ring 0 level auth. Making a whole webpage with lots of graphics and whatnot, sending press releases all over and in general present it like a security flaw on the level of meltdown seems .. false?

Probably court level material.. In any case it seems to have backfired as the stock is up.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by dsacco on Tuesday March 13, 2018 @02:30PM (#16578526)
I think the difference in facts you're talking about is a difference of degree, not category. In other words, it's not plainly false, there certainly is a vulnerability, it's just perhaps exaggerated. I could see a case being brought against the researchers on those grounds, but I'd be really surprised if anything came of it.
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by kbenson on Tuesday March 13, 2018 @04:35PM (#16579547)
It could be interesting. Some of the flaws presented require you flash your bios, if I understand correctly. They are included with what are likely real flaws, but maybe it's enough for a case of misleading the public in part. To me it seems sort of like saying Ford engines have a tendency to blow up, but only after you've overwritten some engine firmware. By itself, not much to talk about, but when attached to something that has indications of being used to make money through stock changes, maybe is more likely to be looked at unfavorably by the SEC?

Maybe not technically a short squeeze (https://en.m.wikipedia.org/wiki/Short_squeeze) but related?

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by noobermin on Tuesday March 13, 2018 @03:28PM (#16578999)
What if it's not false but misleading? That sounds closer to what they are doing here. Sure they included a ridic disclosure agreement that you apparently agree to have read if you continue to read their webpage, and it says something along the lines of "this is our opinion".

It feels slimy and gross.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by dsacco on Tuesday March 13, 2018 @03:46PM (#16579139)
"Slimy" and "gross" are not nearly sufficient for either insider trading or market manipulation. I don't particularly like the way these researchers are acting either, but that's actually because I don't like vulnerability impact being exaggerated and over-hyped. The other stuff doesn't bother me too much.

If the news pushing a stock price is so misleading that it's categorically different from the truth, then I could see a case for market manipulation being brought against them. But I doubt that will happen, because unfortunately people have broad latitude to portray vulnerabilities however they'd like as long as they're convincingly authentic.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by noobermin on Tuesday March 13, 2018 @03:59PM (#16579240)
I was just relaying my feelings in that last bit. But the misleading bit in my comment specifically refers to the fact it's an exaggeration as you put it. So you can flash a bios and make it do nefarious things: that is a true statement but it's hardly a "security flaw" and almost not even too surprising. They are however taking a flaw and spinning it out to be the massive security flaw which it isn't.

I guess that's my question. If you take a true statement and put it out with connotations that it's actually a terribly thing and worse than it is, just being "true" doesn't matter. Stupid analogy, say you go to a bakery and buy bread, then it goes stale in two hours or so by the time you get home. Then you go and write a negative yelp review that this bakery is terrible at baking and they sell subpar bread. You just don't know that the bakery doesn't bake in preservatives that bread you buy from the supermarket does. And it certainly isn't like the bakery is selling spoiled/poisoned bread or selling rocks painted to look like bread loaves.

To add to the other comments here, a recent high profile case of something similar was Bill Ackman shorting Herbalife. Basically, he shorted the stock and then went to the media with his research showing that he believed Herbalife to be a pyramid scheme. Ultimately, I believe he lost money on the whole fiasco, but it's not an uncommon strategy. The whole thing made the news after a particularly amusing exchange between Bill Ackman and Carl Icahn (who had the opposing view) on CNBC: https://www.youtube.com/watch?v=hCZRk1lL90Q. I worked on Wall Street at the time and I remember the entire trading floor at my bank was almost frozen as they were watching this live.

I see.. So it could be a viable business to do research like this, short stock and then release the information. It just has to be a bit more damning than this as the stock price is actually up today!

Seems a bit shady in any case if one were to do this in the same way as when companies pay researchers to make claims publicly that benefit the company like the process leading up to the banning of led in petrol etc.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by matt4077 on Tuesday March 13, 2018 @01:22PM (#16577796)
No. Doing independent research is not “inside information”. This is actually pretty close to how a market is supposed to work.

It’s also not market manipulation to publish factual information or opinions. Only knowingly publishing false information would qualify.

I tend to imagine that if Intel were doing this they’d do a better job of it. Even if CTS-Labs are completely legit, the way it’s been done has led to immediate suspicion of the claims and people involved, in a way that feels much more like a small group straining for attention or to make a quick buck and making a bit of a mess of it. If Intel were involved, I’d expect it to be done more professionally and simply better, so that people don’t suspect foul play and go looking for problems. It is possible for a company to deliberately obfuscate the trail by doing it this way, at the probable cost of some effectiveness (though if the claims are overblown it might perhaps be more effective this way), but it seems less likely.
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by chrismorgan on Wednesday March 14, 2018 @02:18AM (#16582751)
A really fun interpretation of it is AMD doing it themselves, deliberately badly, so that they can come off as the wounded party that actually have really good hardware. Risky, but probably not impossible to carry off.
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tripzilch on Friday March 16, 2018 @10:53AM (#16601061)
While fun, it would also mean they would be publicly disclosing vulnerabilities in their own systems and then deliberately withholding the patch, just to put on this shpiel in order to appear as the underdog?
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by chrismorgan on Friday March 16, 2018 @11:02PM (#16605397)
Confirmation that the vulnerabilities are legitimate pretty much writes this one off. At the time I wrote it this wasn’t entirely clear, though it seemed probable (though even then they could have been overstated).

People here seems to be mentioning short sellers being connected to this research as if there's some sinister collusion going on. This is the entire point of short selling, and SEC encourages this type of activism. It allows people who can provide expert knowledge to profit off a trade if it can reveal damaging and legitimate information about a company

For example, a short seller last year revealed (through extensive research), that Valeant Pharmaceuticals was stuffing its channels and faking its finances. He placed a huge sort sell and went public with the damaging info - tanking the stock from $270 to $12 and made a ton of profit off of it: https://www.nytimes.com/2017/06/08/magazine/the-bounty-hunte....

Without this incentive, why would anyone bother to reveal damaging info? You're placing your self as a target with no reward. The payment is the natural balance of the market.

So yes, this research firm is connected w a hedge fund, and they have a very vested interest. But that doesn't make their claim untrue

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by kbenson on Tuesday March 13, 2018 @04:37PM (#16579555)
CTS-Labs is very forthright with its statement, having seemingly pre-briefed some press at the same time it was notifying AMD, and directs questions to its PR firm. The full whitepaper can be seen here, at safefirmware.com, a website registered on 6/9 with no home page and seemingly no link to CTS-Labs. Something doesn't quite add up here.

Anandtech is reporting on the situation more than the flaws. That does require covering what the flaws are though. Not covering it at all isn't exactly performing good journalism either.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tptacek on Tuesday March 13, 2018 @01:17PM (#16577746)
Independent researchers don't owe AMD a chance to address anything. They bought the chips on the open market where AMD makes them available, and then used their own time and materials to conduct their own research. Their work product is their own, and AMD has no claim to it.

There are, as I see it, two rational, coherent ways to be outraged about this story:

1. The vulnerabilities are fabricated and the report is fraudulent, in which case, by all means, slag the researchers.

2. The vulnerabilities are real, in which case. AMD is an 11 billion dollar company that got outmaneuvered by what appears to be 4 dudes in a basement.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by eropple on Tuesday March 13, 2018 @01:35PM (#16577945)
People use AMD chips. It's about more than AMD's stock price.

I do not need to be a security researcher to understand that they, as with everyone else, have an obligation to the body politic to not be a dick (as in all things!). There are actors who may be aware of this attack already--but, as I mentioned elsethread, wider knowledge of attacks like this have a much higher chance of splashing back on end users who literally don't know any better than it does AMD. I mean, I couldn't give less of a shit about how AMD feels--they'll be fine regardless--but there are people downrange of this, not just some company.

This is shoot-the-hostages stuff, and I believe that you are better than to be OK with that.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tptacek on Tuesday March 13, 2018 @01:49PM (#16578096)
You can consult the search bar at the bottom of the page to learn that I am 100% OK with immediate, uncoordinated disclosure. It's not what I personally do, but that's easy for me to say because I don't find these kinds of vulnerabilities.

This isn't "shoot the hostages". The researchers didn't manufacture the vulnerabilities; AMD did. If 4 dudes in a basement can find exploitable driver vulnerabilities, so can 10 researchers none of us will never have heard of working in a nondescript office somewhere in Bulgaria. The only moral differences is that these 4 dudes told us about what they found --- something else they had no actual obligation to do.

Again: it seems really likely that these vulnerabilities have been hyped way out of proportion to their real impact. I think it's reasonable to be irritated by that (again, though: this isn't a first). But other than that, I don't understand how people arrive at the conclusion that independent security researchers owe strangers the results of their work.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by eropple on Tuesday March 13, 2018 @01:57PM (#16578163)
I understand what you are OK with. I am saying that I believe, from a fairly long scope of interaction, you are a better person than that.

They've disseminated widely an attack strategy to people who didn't have it. Nobody except AMD can fix the problem, regardless of the good intentions of other actors--on the other hand, many bad actors can use that information. That's as shoot-the-hostages as it gets.

Security researchers owe "strangers" (which is a really weird term for "society at large" that I don't think you, specifically, would be using with such connotations outside of a security context where you'd already made a decision) the same courtesy they owe everyone else: to not endanger people unnecessarily. I agree with you that this is a relatively minor vulnerability, I'm not hyping it or anything--but it's still a vulnerability, it is still more widely known now, and there is a bigger pool of bad actors than there was last week able to use it against people, irrespective of AMD's stock price.

There's certainly a gray area, if a vendor hasn't acted to fix something you know they know about. I'm not talking about that. But 24 hours and briefing the media before letting AMD know, as it very much seems like they did, is well outside of what I could consider any reasonable gray area.

If you care about end users, and you should because they are your fellow people, you don't publicize how bad actors can hurt them. You just don't. It's just...minimal decency, to care about other people. I can't see it any other way.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tptacek on Tuesday March 13, 2018 @02:06PM (#16578261)
I strongly disagree with the reasoning you're using here.

The premise of your argument is that without vendor cooperation, end-users are helpless to mitigate the impact of security flaws.

No, they aren't. Not only are they not helpless, but many of them are in fact ethically obligated to mitigate exposures with or without the assistance of their vendors. Almost every end user has at least one last-resort mitigation for any vulnerability: the power switch.

Most of the time, most users have better non-patching mitigations than that. These vulnerabilities are all post-compromise privilege escalation flaws. Their exploitation is situational and most users can do things to eliminate the situation that enables their exploit.

You might not like the fact that end-users have to make hard, expensive choices about how to mitigate flaws. But if you think about it for just a second, you'll see that the idea that patches were saving them from this choice was fallacious. There is no reason to believe these 4 dudes were the only ones in the world capable of finding these flaws (the reality is that if they're the only ones who know about them, it's because the kinds of flaws they found simply aren't important enough to demand focused attention from others). All restricted disclosure does is prevent end users from making the choice for themselves.

I believe that as a general rule, we're better off when we have the most information available to us about vulnerabilities. Personally, I'd probably stop short of publishing exploit code. But other researchers that most of us respect a great deal in the abstract do not have that particular scruple, and some --- like the original Metasploit project --- made it a point to publish exploit code immediately, patch or no patch, to arm operators with information about their exposure.

This isn't an idle opinion. If there was working Usenet search in 2018, you could find me making approximately the same argument back in the 1990s, when I worked as a researcher at SNI, the world's first commercial vulnerability research lab.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by bostik on Tuesday March 13, 2018 @04:24PM (#16579465)
> These vulnerabilities are all post-compromise privilege escalation flaws

I would say they are all invasive evil maid threat vectors. Each one requires either physical access to the hardware or (as you stated) an already established root privileges. We all know that if you have physical access to hardware, it's essentially game over.

However. One of the vulnerabilities supposedly allowed to subvert UEFI secure boot. If that's true and allows to boot arbitrary media, then the others are equally feasible, because an attacker can boot into a root shell of their choosing.

The timing in this disclosure reeks of malice, though. Giving a 24h advance warning basically allows the outfits to claim that they disclosed vulnerabilities to manufacturer before going public. Technically true. Just highly misleading and dishonest.

I have personally no beef with full disclosure, and have advocated it as a viable mechanism since the mid 1990's. I also happen to think that responsible disclosure is a good approach, but it definitely needs the threat of FD as a stick, because otherwise vendors would not have any real incentives to work on addressing security bugs. Name-and-shame does work.

Let's get back to AMD flaws. Giving a really short window? Basically just enough to have an initial PR response ready? Have the decency to go full disclosure. Or give a full month. AMD won't be fixing the bugs before news breaks in either case. Just don't claim this is anything but a maliciously crafted exercise with ulterior motives.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tptacek on Tuesday March 13, 2018 @04:28PM (#16579493)
While I'm fine with criticizing them for partial disclosure, I again have a problem mapping any of this back to ethics, because, again, independent researchers do not have an obligation to vendors or to any amorphous public. As long as they aren't literally exploiting (or arranging to have exploited) vulnerabilities to break into people's computers, or lying about what they found, I don't think ethics have much to say about what they should do.
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tripzilch on Friday March 16, 2018 @12:11PM (#16601579)
> I don't think ethics have much to say about what they should do.

What does that even mean? What do you think "ethics" means? This is a nonsensical statement.

The consideration of what people in certain situations should or should not do, IS ethics.

Even if someone would say (for some reason) "but researchers should be able to do their work without consideration", that is making an ethical statement.

I understand why you would have a problem mapping this back to ethics, because if you'd formulate it as such, it would sound kind of bad: Researchers have no ethical responsibilities to the public.

You can't choose to not let decisions be guided by ethics, that's like claiming you choose to find your way without navigating. It makes no sense.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by Erlangolem on Tuesday March 13, 2018 @05:14PM (#16579858)
No obligation to vendors, no obligation to the public, so what are your ethical standards exactly? It sounds like committing crimes is it, but that’s a legal standard and not an ethical one. At what point are you less of a researcher and more of a sociopath with a keyboard? What makes researching software vulnerabilities such a uniquely non-ethical undertaking compared to all other forms of research?

You seem like a living argument for ethical standards being imposed on your industry, by law if needed.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tptacek on Tuesday March 13, 2018 @06:38PM (#16580512)
In exactly what way are you harmed by someone discovering a vulnerability --- that existed whether or not they did the work --- and then telling you about it?

You're arguing that the force of law should prevent you from learning inconvenient things about the software you use.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by gjm11 on Tuesday March 13, 2018 @08:26PM (#16581184)
You are not harmed by someone discovering a vulnerability and telling you about it. Obviously that benefits you rather than harming you.

You are harmed by them discovering a vulnerability and telling the world about it.

And if they discover a vulnerability and tell both you and the rest of the world, the harm may easily outweigh the benefit.

Suppose I go wandering around the city where you live, checking for unlocked house doors. I find that you've left your front door unlocked and gone on holiday. I then wander the streets shouting "Thomas's house is unlocked and no one's at home!". I also phone you up to let you know your house is unlocked.

It was your fault, not mine, that the house was unlocked and no one at home to deter burglars. In principle, anyone else could have come along and burgled your house, if they'd found it before I did. None the less, I think that in this scenario I have done you wrong.

The argument against your position that people are trying to get across to you is not that. It is that publication of vulnerability without giving heads-up and time to prepare solution to the vendor greatly increases the risk that a user will be harmed by attackers exploiting the public knowledge. Often substantial number of users are not going to mitigate or resolve the problem without their vendor giving out the official solution.

From this and other similar responses of yours here I think that you do not have a convincing way to resolve the obvious problem with the absolutist 'i can do whatever i want with my research' stance that people here pointed out to you. So you do whataboutism directed at vendors, misrepresent people's arguments or try to pivot the discussion. Perhaps it is time to write less and let the discussion sink in a little. You may find a better way to argue your point, or even find you no longer want to do that.
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by kelnos on Tuesday March 13, 2018 @11:50PM (#16582134)
I don't think anyone's arguing that a researcher has a responsibility to tell anyone. If they find a vulnerability and then decide to completely shelve it, that's fine (if maybe a little pointless?). But if they do decide to do some kind of disclosure, I (and others) would argue that researchers have an ethical responsibility to do so in a way that they believe will do the least harm.

It's certainly reasonable to argue which kind of disclosure is the best way to achieve minimal harm, but my opinion is that it's unethical to disclose without considering what method of disclosure will do the least harm, or, worse, just not caring and going for the "biggest splash", as is what it seems these researchers did.

”The premise of your argument is that without vendor cooperation, end-users are helpless to mitigate the impact of security flaws.”

I know everyone in my family is ignorant of this “disclosed” security flaw and is powerless to mitigate the vulnerabilities disclosed on their own. Even if they did know to “turn off their computer” as someone said, are they supposed to wait until someone calls them to tell them a patch is ready?

Disclosing a vulnerability for profit at the expense of everyone else is a shitty thing to do. Would giving AMD a few days to fix it have hurt as many people as giving them one day?

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tptacek on Tuesday March 13, 2018 @08:10PM (#16581098)
How many vulnerabilities are you capable of finding in software that everyone in your family uses, and can't find for themselves? I'm sure the number is not zero. Is it unethical for you not to go look for them?
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by kelnos on Tuesday March 13, 2018 @11:51PM (#16582143)
Looking is fine. Disclosing in a way that's likely to cause harm that could otherwise be minimized with a little care... not so much.
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by eropple on Tuesday March 13, 2018 @02:19PM (#16578419)
This is probably where we diverge. From where I stand, "end users" are incapable of making a meaningful decision about security at this level. It would be awesome if they weren't, and god knows I have spent a decent amount of time in my life trying to bootstrap people into such a position, but it doesn't...like...work. There is a computing priesthood, as much as we have tried to democratize this stuff, and it's all goddamn nonsense to those outside of it. The set of people I know who do not actively work in tech and can make meaningful decisions about the technology they work with is...my girlfriend, probably. Can't really think of anyone else who isn't reliant on "do this" the advice of others, whether it's correct or not.

Continued education to help end users get to the point where they can make meaningful and educated decisions is great, and should be pursued, and I do it where I can (though most of the time there's just a shrug and a "whatever"). But, barring that, somebody's gotta make choices on their behalf, and there's a Jerry Garcia quote for this one, you know? With great power comes great responsibility, and we gave ourselves that power. And, outside of a security context, this is why I unflinchingly come down on people who work for shit companies that hurt people, why I'd never hire someone who worked for, say, a toolbar vendor in the 90's/00's and why I have fired clients before when I discovered they were doing shitty things with data gleaned from people who trust them: because we have ethical responsibilities to the people downstream of us who are ill-equipped to make meaningful, educated decisions. I can't compel anyone to do as I do--but I can say that one should, because it's decent.

I can't agree that the power switch is a reasonable mitigation in 2018. In the nineties, sure, but too much of life revolves around this garbage we invented and keep mostly creaking along. (Should it? Probably not. Does it? Yeah.) We are on a ratchet, we can't go back, and kicking the decision down to people who literally-literally lack the tools to make a wise decision while painting a target on them for bad actors who can take advantage of them is profoundly disturbing to me.

This particular vulnerability is a post-compromise privilege escalation flaw, yes. But it strikes me that the conversation must be bigger than that, because the same arguments are used for both. This? Low stakes. Heartbleed? Incalculably high stakes. But the same argument could/would (if it were found by shitheads rather than people with a certain amount of decency to them) be used for the latter instead of the former, and that's what makes me itch.

(And to be clear, irrespective of this conversation, you know I am a big fan.)

So the 11 billion dollar vendor who shipped vulnerabilities in the first place gets to treat these problems as an externality, but 4 dudes in a basement who did a basic research project have to be restrained from speaking?

I don't see how you get there from here.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by eropple on Tuesday March 13, 2018 @03:20PM (#16578939)
I don't get how you get to me thinking the vendor gets to treat these problems as an externality? I am all in favor of slagging vendors who release buggy shit. For hardware (and some software) manufacturers I'd be in favor of significant legal remedies available to people who purchase hardware later found to contain security vulnerabilities.

But I think that should be done after mitigations are in place to protect end users, or if the vendor is not taking good-faith steps to mitigate the problem.

And I am not saying one should be "restrained from speaking" at all. I am saying that choosing to do so makes one an asshole, and that decent people should strive to not be assholes.

I don't understand the chronology you're working from. The timeline here shouldn't start from "when the independent researchers find something in their basement". It should, rather, start from "when the first MRD for the product is sent from the PM to the development team". That's when the clock starts ticking on mitigation. AMD had years.

An eye for an eye works only until everyone is blind.

You seem to have several deeply misguided premises.

1. We don't know ARM knowingly shipped these chips although they were vulnerable. Bugs happen.

2. Even if this was the case, an individual can show, and ought to, show decency and empathy towards others.

3. This last comment of yours is a straw man and I doubt you are incapable of seeing this. You parent's argument was much more nuanced and elaborate than your rebuttal.

That's an impossibly low bar: all you have to do to "not know" is to not spend any money on security verification. The complaint here is that AMD was outdone on verification by 4 dudes in a basement.

I think saying that they were outdone by 4 dudes in a basement is being intellectually dishonest. There are a lot of dudes in a lot of basements looking for vulnerabilities all the time. Those four happened to find it, but there were hundreds of others looking. There’s no amount of money that amd can spend that would make them not outgunned eventually by all the hackers and intelligence services and security researches looking to break it.
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tptacek on Tuesday March 13, 2018 @06:40PM (#16580525)
Why do you assume that there were hundreds of other people looking for these vulnerabilities? Chances are, when we learn the technical details, we're going to find out that they're bog-standard memory corruption flaws in driver code, and that the thing that prevented anyone from discovering them was that nobody looked for them.

Have you ever worked with a code base before? Even when you scrutinize for bugs, they still can go unspotted. Sometimes hundreds of people can look at the same code and not see anything wrong with it. Software has the benefit of having higher levels of abstraction, I haven't designed any hardware but as far as I'm aware it's not easy to abstract it. That will make it much harder to find things. While 4 guys in a basement may have found this vulnerability, it doesn't mean they will find every vulnerability or that anyone else would have this as they had. Throwing money at verification will not make it fool proof.

> If there was working Usenet search in 2018, you could find me making approximately the same argument back in the 1990s, when I worked as a researcher at SNI, the world's first commercial vulnerability research lab.

This being a controversial topic straight at the intersection of technology, the way it changed and affected society, the public good and our dependence on technology, I really don't think that "I haven't changed my mind about this in 28 years" supports your argument ...

And honestly I would say that whether I agree or not.

I wasn't working in security but I definitely moved my opinion on the matter. In the (late) 90s I was mostly for full public disclosure arguing the same "we're better off when we have the most information available to us". But today I'm leaning way more towards "responsible disclosure is good" (as you can tell I'm also not 100% black-and-white on the matter like you said you are).

Maybe it's because I was younger then and had more of a reckless mentality and an innocent belief that people will make the right choices given enough information.

Maybe it's because in the past 28 years technology has changed our society to such an extent that impact of security vulnerabilities is rather incomparable to the impact they had back then.

Maybe it's because I definitely don't believe that you can defend this opinion with the very same arguments that were used back then without even addressing the spread of information technology and the drastic way they altered society in the past 28 years.

Maybe it's because I now realise that I myself am not always better off with more information if I can't act on it, and therefore it's not reasonable to assume it as a general rule. Which is very much something I had yet to learn 28 years ago, had to swallow some pride. I wish everybody was a clever as I was back then ...

So if a hospital runs a life support on a vulnerable chip, they should just hit the power switch until it's fixed.

Or what about a computer controlling a nuclear power plant? An airplane? Spacecraft or Satellite?

Vulnerabilities don't restrict themselves to equipment that is non-essential for people to survive or would cost millions to replace in consequence of a hack or shutdown (please try to revive a sat after you did a full shutdown, I will be awaiting your report on how you'll align the antenna)

Alerting folks to the danger that they face is one way to do so. Responsible Disclosure is caring about the vendor, whereas full disclosure gives other people the chance to take action on their own to remove themselves from harm.

As another note, why not argue for Responsible Development? This is where the outcry should be. Flaws in products come about because they are shipped before they are finished.

> Responsible Disclosure is caring about the vendor, whereas full disclosure gives other people the chance to take action on their own to remove themselves from harm.

That is true, but you missed the other side of the argument. Coordinated disclosure is preferable also to a part of users/customers. Significant part of them have no understanding or incentive enough to mitigate on their own. So the question the discoverer of a bug then faces is 'how much headstart should I give the vendor and the users that depend on the vendor, before I make this public'? This has no universal answer, it may depend on how long the bug is out there and what kind of users may be harmed. But it is easy to see that a little headstart in terms of weeks is more reasonable than headstart=0, especially for bugs that are out there for years.

> why not argue for Responsible Development? This is where the outcry should be. Flaws in products come about because they are shipped before they are finished.

Flaws are not always due to cutting corners. Some bugs in computers are very unintuitive and it could be years before they manifest. More responsible development seems like a good idea, but again, this ignores the other part of the problem - major group of users do not understand the intricacies of development and are not willing to buy more 'responsible' product, if it is 5years behind the newest trend and costs 5x as much.

How does that matter? The only thing that matters is the harm that certain types of disclosures will do to average users. It doesn't matter whether a bug could have easily been found before release or not; the bug is there, in the wild, in a position to harm users.

By all means, vendors should be taken to task, and be beaten up even more when a bug was easily avoidable. But a bug's stupidity is completely unrelated to how a user might be harmed by an "irresponsible" disclosure. Giving the vendor their just desserts is secondary to that.

I disagree. This does not account for the fact that malicious actors are likely to exploit these before the vendor fixes them on a schedule that they would prefer to dictate. And all users are not incapable of making alternative judgments about the use of vulnerable technology. Users include my Mom, hackers at small companies, giant corporations who are capable of overnight turning off SMB V1.

The harm to users comes from vulnerable software that the vendors put there in the first place.

> I do not need to be a security researcher to understand that they, as with everyone else, have an obligation to the body politic to not be a dick

So are you talking about AMD being dicks by releasing buggy chips, or the researchers somehow being dicks for finding out?

Related question: if a "food security researcher" discovered a vendor was selling contaminated produce - would it be reasonable for them to give the vendor 90 days notice before telling the public?

While I think it's reasonable and appropriate professional practice for _some people/teams_ to go down the "coordinated disclosure" path (I think the world is a better place for having Tavis Ormandy disclose the way he chooses to), it does without doubt benefit the company who's products are flawed more than the researcher or the public. Anybody who knows they work at a firm that's going to be described dismissively like AMD here did "This company was previously unknown to AMD" is quite likely correct to publish-and-be-damned, because you can bet there's a non-zero chance that AMD's response to non-public disclosure is going to include either stonewalling and stringing the problem out as long as possible, or lawyering up ad threatening to sue the "previously unknown to AMD" company into oblivion.

If you don't want public disclosure of security flaws about your products, either don't make flawed products or don't ship them to the public. Especially if some of the key selling features of said product include bullet points like "AMD Secure OS".

Unless they released it maliciously, I don't hold it against them. And wouldn't call anyone a dick unless they planned to do something evil.

Exceptions: issue was known but got ignored due to release schedule, or security was never mentioned in the project and at no level was there any security consideration. But that's for specific management issues, not engineers or the vendor in general.

What's important aren't really the bugs, bugs can be fixed. What's important is who is allowed to run, inspect, share, and modify the code. If only the copyright holder is allowed to do this, that's proprietary software and that's malicious. If a user's software freedom is respected so users can choose to fix it themselves, wait for another release, hire someone else to fix the code, or live with the bugs that's treating the user properly.

Everyone makes mistakes; it's more about how those mistakes are handled and if a user's control over their computer is respected.

The goal of responsible disclosure windows have nothing to do with saving face for the company. The point is that it gives the company time to come out with a fix so that their customers aren't left with massive holes in the security of their systems.

That presumes the only response people have to vulnerabilities is to patch. But that's never the only response people have: people can trade availability for exposure. But because nobody in the industry wants to face a costly tradeoff like that, we pretend that we're stuck with the lowest common denominator response.

Btw, your HN search result page links to all of the references that you THINK what the term "Responsible disclosure" means. Be it "coordinated disclosure" or whatever else, I don't care. But I don't think it's ethical to disclosure the security vulnerabilities to the wild without contacting the vendor and given them a timeline (should be MUCH LONGER than 24 hours) and the benefit of doubt first.

Hypothetically speaking, if you are researching vulnerabilities solely for the intent of money (because you can sell to them to 3rd parties or your side hedge fund business can profit from disclosures in the stock market) then shame on you, because you are doing the society a dis-service and gaining on everyone' losses. To me, you are as evil as those hacker who utilize them.

There's a decent counterargument - take it or leave it - that this kind of research is extremely difficult and expensive, and upon success, privately weaponizing it and/or selling it to organized crime or nation state-level actors is extremely attractive, and therefore, the ability to short the stock of a sloppy/insufficiently-careful HW vendor to fully or partially fund the research instead is legitimate in that it ultimately improves overall-societal welfare relative to those other alternatives.

Vendors who wish to discourage that behavior could offer comparably-large bug bounties instead. And, of course, make their products more secure in the first place.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by paulmd on Tuesday March 13, 2018 @08:56PM (#16581365)
Seriously, if some fly-by-night security outfit has managed to discover this, they're probably not the only ones.

They didn't blow full technical details on this exploit after 24 hours, they went public with a summary... one that's so high-level that many people are even doubting they exist. That's not exactly dumping a zero-day on the internet either.

There's a whole lot of shooting-the-messenger going on with this topic. Making plays against the stock is scummy and possibly illegal, but that doesn't make the exploits here any less real (assuming they are). These are actually quite serious breaks, potentially VMs can jump the sandbox straight into SMM mode and PSP, so it actually is much more severe than just "root password lets you do root things".

https://twitter.com/c7zero/status/973668616183754753

There is a long and storied history of showing the disadvantages of your competitor's products. Edison went on a campaign against Westinghouse's AC electricity, culminating in him electrocuting an elephant to death to demonstrate how dangerous it is.

Right now we need more spotlights on computer security than ever, and as long as it gets bugs patched (hardware, software, or firmware) I don't really care who's doing it or what their short-run motivations are. If AMD won't secure their code appropriately and Intel wants to call them out, fine. If Intel is leaking timings through sidechannels and AMD wants to call them out on it, fine.

And if we want to throw stones here, it was AMD who blew the embargo on Meltdown a week early because they wanted to force a response from Intel at CES... different in degree, not really in kind.

So you believer in the absolute freedom of security vulnerabilities disclosures and security researchers should just do so at will?

Do you know that the general public are usually the ultimate victims and impacted by those vulnerabilities the most?

Especially Intel/AMD are corporations worth tens of billions monopolies in their fields, and if their CPUs with zero days unpatched and sample code and exploitation techniques out in the wild, what else are you gonna use on your desktop computers?

We've seen similar happened for Microsoft after Shadow Brokers's disclosure.[1] It's gonna be worse for hardware products as it's virtually impossible to retroactively fix silicons chips.

> What about responsible disclosure ethics?

"Responsible" to whom? Terms like these indicate what side one takes, such as how one expands the term "DRM": digital rights management means taking the 1%/elite side favored by the publisher, the few in power. 'Digital restrictions management' highlights what's happening from the user's side, the 99%, the side of the many. Similarly with the harm to the users and the desire for freedom in the term "jailbreaking".

So, since we recognize the reporters owe AMD nothing, to whom are they "responsible"? Or what are they responsible for?

This phrase strikes me as useless except to try to foist a responsibility on people that they don't actually have and getting the relatively powerless to serve the interests of power -- users who can't inspect, edit, or share edited CPU microcode are somehow not acting responsibly if they don't give proprietors sufficient notice.

Where is the "responsible disclosure" for Intel when they refuse to let users fully control the signing keys used in the software that sees every network packet before the rest of the computer (for inbound network traffic) and before a packet leaves the computer (for outbound traffic)? The one-sidedness of it all sticks out like a sore thumb.

3. The vulnerabilities are minor, barely worse than normal expected behaviour; just enough to call them vulnerabilities. All these "exploits" consist of using ultra-privileged access (signed device drivers, or flashing the BIOS) for bad purposes.

In the white paper, many attacks are hypothetical and many phrases are vague and slippery, suggesting the "researchers" barely achieved execution of something, not real payloads.

I hope AMD invests the little money needed to fund this sort of PR campaign, er, research initiative, against Intel. The net result would be a greater awareness of the perils of "sponsored" science and of the poor state of PC security.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by tptacek on Tuesday March 13, 2018 @06:42PM (#16580539)
You're recapitulating an argument that Arrigo Triulzi posted on Twitter based on his reading of the CPS-Labs white paper. The white paper doesn't include technical information about the flaws.

Dan Guido and Trail of Bits got to read the actual report, and vouched for them as real vulnerabilities. The fact that there are vulnerabilities in signed drivers is a bad thing: it means that AMD shipped cryptographically signed versions of vulnerabilities. Arrigo's twitter thread implied that the use of signed code somehow mitigated the vulnerabilities, but the opposite thing is true.

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by bigiain on Tuesday March 13, 2018 @07:08PM (#16580715)
Pwn2own, iOS jailbreaking, and Playstation hacking have shown time and time again that chaining up seemingly innocuous exploits to get to the stage where you can run a "minor exploit which requires ultra-privileged access" is definitely within the reach of bored/smart teenagers with no more motivation than a new laptop or gaining the ability to pirate or cheat at games...

Suggesting this is "just hypothetical" because "nobody is going to get physical access or code execution in a signed driver" is pretty shortsighted in my opinion...

Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by HelloNurse on Wednesday March 14, 2018 @04:20AM (#16583169)
When the enemy manages to install a signed driver or flash the BIOS, the difference between being 100% owned by design and being 105% owned because of this sort of vulnerability is the last thing to worry about.

I wonder if the unusually short disclosure process was related to their disclosure of related financial interests.

If it was, it’d seem that this research was in support of a financial play similar to how Muddy Waters shorted St. Jude Medical on the basis of insecure medical devices. That would appear to be a legitimate strategy, but if the market didn’t punish Intel for their processor vulnerabilities it seems likely they’d react similarly here and the research would fail to move the stock price in any significant way.

Except that's not necessarily something to get "outraged" about, just something to keep an eye on while this story develops.

The only one I see shouting "this is an outrage!" appears to .. be made of .. straw?

2. Shouldn’t be news given that a couple of dozen Saudis outmaneuvered a superpower, taking out two skyscrapers and thousands of people. That’s also no excuse for the behavior in question.

I’ll add 3. It’s not all about the researchers and AMD, but the people who use AMD chips and deserve a modicum of protection and consideration. Unless there were exploits in the wild, the security of users seems not to have entered into this.

I'm not saying it was them, but I wouldn't be surprised if Intel was trying to recover its reputational damage by hiring ppl to heavily research breaks in AMD chips to even the reputational playing field. They're the ones that stand to gain the most from this legal but shady tactic and have been reportedly scared of losing their long held market dominance in desktops and servers. Iirc AMD wasn't vulnerable to Meltdown which I speculate changed the market calculus in ways detrimental to Intel that both companies would be well aware of.

Interestingly, you'll note that the researchers claim public interest as their reason for non-standard practices, but then later it is revealed you need admin privileges to exploit them. The rhetoric the researchers use is inflammatory and staged in a media savvy way like a PR campaign.

This is a totally evidence free assertion and I'm not an infosec person (and am therefore happy to be set straight by experts) but I'll be happy to crack open the popcorn if something interesting is revealed a few years down the line.

I wonder if this is could be Intel up to its old tricks again.

This is so fishy to me, it's so unprofessional of a security researcher. My tinfoil hat is already rattling...

Nice non-sequitur. Somehow the limiting factor on the ability of someone to judge professionalism is the number of papers they've written?

No, I'm just noticing again that people who don't don't do a lot of vulnerability research have a lot of interesting opinions about the professional norms of people who do that work. But you never know --- maybe they do a lot of research, in which case, yes, their opinion on security research norms is a lot more interesting to me.

I am not a security researcher, and I do not speak for the person you are replying to, but I do believe that Intel's documented history of unethical, anticompetitive practices against AMD, for example, deliberate compiler handicapping for non Intel CPUs[1], is enough evidence to establish at least some suspicion regarding these results, especially considering the short warning given to AMD before public disclosure.

I also wonder, what is the purpose of such white hat operations if vulnerabilities are disclosed publicly without anywhere near adequate time for a fix? Isn't SOP to give more time before going public?

I'm not arguing about Intel. If you think this is a giant conspiracy by Intel, more power to you --- I'm not engaging further on that.

What’s the background here?
Re:Security Researchers Publish Ryzen Flaws, Gave AMD 24 Hou... by Digital-Citizen on Tuesday March 13, 2018 @01:28PM (#16577860)
> 1-day notice? Such aggressive wording without even the chance for AMD to address the concerns?

Are the reporting parties under any obligation to give AMD notice?

Behaving according to AMD's wishes is not an obligation. Businesses will be the first to tell you that agreements and laws form obligations, not what someone perceives as a nice thing to do.

If not, then you're reacting to a distraction, a detail that doesn't matter: how the corporate-friendly tech press is trying to shift blame away from the party that either sold CPUs with bugs in them (mistakes happen, and this is unfortunate) or distributed nonfree (proprietary, user-subjugating) software which also happens to contain insecurities (a malicious and unjust way to distribute software).
