'Unfixable' security flaw in Intel boot ROM
- stoicShell 7y agoThe useful gist: > "To fully compromise EPID, hackers would need to extract the hardware key used to encrypt the Chipset Key, which resides in Secure Key Storage (SKS)," explained Positive's Mark Ermolov. > "However, this key is not platform-specific. A single key is used for an entire generation of Intel chipsets. And since the ROM vulnerability allows seizing control of code execution before the hardware key generation mechanism in the SKS is locked, and the ROM vulnerability cannot be fixed, we believe that extracting this key is only a matter of time. > "When this happens, utter chaos will reign. Hardware IDs will be forged, digital content will be extracted, and data from encrypted hard disks will be decrypted." And this formidable response as usual: > Intel says folks should install the firmware-level mitigations, "maintain physical possession of their platform," and "adopt best security practices by installing updates as soon as they become available and being continually vigilant to detect and prevent intrusions and exploitations." When will it stop? How deep run the flaws in Intel's platform? Is AMD equally exposed?
- OrangeMango 7y ago> "maintain physical possession of their platform" That ship has sailed.
- mysterydip 7y agoWhat about physical possession before you own it? Will this potentially sour a used/refurbished market?
- rolph 7y agothis is more about the chipset on the motherboard. to backdoor this you need to saddle a chip or a connector onto the PCH chip and win the race to takeover the bus. or if your intel and you send a firmware update to modify the ME behaviour /state. it would be fairly suspect in most cases but if this was done at the factory, it would be hard to tell for most people. What really matters is just how much of a target you might be for someone to take the effort to engage in what really amounts to industrial/corporate espianage.
- Bnshsysjab 7y agoHow far fetched would nation states performing this at airports be?
- rolph 7y agoin socratic fashion... how long does it take for a machine to be opened and booted up, and what sort of charade would be required to make the opportunity. if someone flatout stole your laptop, how long would it take for you to notice its been replaced by a stand in? would someone have the opportunity to swap your real laptop back to you unnoticed? and seriously it doesnt need to be a nation state that does this, as all you need to be capable of physically is to inject digital pulses into the bus crafting an exploit is where the skill comes in. some people are motivated just by the opportunity to stir a pot.
- castratikron 7y agoOn the contrary it sounds like the secondhand market is going to be flooded with used laptops very soon...
- dexen 7y ago>That ship has sailed. Not in the least. "Cloud" is merely the modern spin on "terminal in the office, mainframe at the HQ". We moved from terminals to local mini/microcomputers back then, and we will move from "cloud" to edge computing again. Notably, serverless and "installable web apps" are already a growing thing. And no, Sun, the network is the computer will not come to pass during this cycle.
- yjftsjthsd-h 7y ago>> That ship has sailed. AWS makes up a massive fraction of the whole internet. That ship has absolutely not sailed. If your company doesn't own the mainframe, it doesn't control the hardware. > And no, Sun, the network is the computer will not come to pass during this cycle. ... we are arguing about this via web browser. O365, Google docs, Dropbox, iCloud and company are common ways to work with documents, SaaS has been a wild success in business, and major players (no pun intended) are pushing game streaming. The network isn't the only computer, but for a lot of people it's the main one.
- dexen 7y ago>If your company doesn't own the mainframe The historical mainframes usually were rented from IBM and the likes. Less sunk investment, less reasons to stick with it. >we are arguing about this via web browser Which works equally well for remote AND local resources. Electron is popular for a reason. All the centralized services - online Docs, Dropbox, Github etc., - are more subject to disruption and replacement than they would want you to believe. SaaS has been a success in the same way "bring your own device" was a success - an end-run around the ossified, slow-moving and bureaucratic ICT department. It was nimble, fast and elastic; allowed for quick iteration and experimentation. Now that the SaaS is a big game, it's subject to the very same kind of disruption. Take a look around, you'll see people using local Git repositories, and locally hosted web-based services to get shit done. Just to avoid the hassle of procurement & upkeep of big-name SaaS. Containers let you move the data & code to unmanaged iron where it's close to the user, instead of one big managed datacenter. SaaS and datacenter computing is not nimble anymore; local is nimble, and Google Stadia delivered the eulogy.

- SpicyLemonZest 7y agoI think the average company should and does trust the physical security of Amazon's datacenters more than their own. If I had a nickel for every unvetted janitor allowed to clean an office alone near an easily pickable hardware closet...
- fredgrott 7y agolet's put this way Apple's redesign Mac laptop launch in 2021 is not using intel chips but their own chip
- matheusmoreira 7y ago> When this happens, utter chaos will reign. Utter chaos? I don't think so. > Hardware IDs will be forged Seems like a victory for privacy. Who wants to be tracked via hardware IDs? > digital content will be extracted Any victory over DRM technology is a good thing. The only people shedding any tears will be those in the copyright industry. > data from encrypted hard disks will be decrypted People actually rely on proprietary hardware encryption? They should have learned the lesson when built-in SSD encryption turned out to be worthless.
- gowld 7y agoAnybody who doesn't want their data copied will be shedding tears. Including anybody with private files. You are more than welcome to decline to use DRM if you don't like it. Just don't expect people to give you copies of data they don't want shared by you.
- matheusmoreira 7y ago> Anybody who doesn't want their data copied will be shedding tears. "Their" data? What a ludicrous concept. It's analogous to saying people own numbers. > Just don't expect people to give you copies of data they don't want shared by you. I fully expect people to distribute "their" data far and wide to anybody who asks for it. That's what copyright is all about: giving people the illusion they're in control of what happens to that data. The truth is only one copy of the data is needed. Once it's out there, there are no limits to what can be done with it.
- outworlder 7y ago> "Their" data? What a ludicrous concept. It's analogous to saying people own numbers. Oh. In that case, where have you posted your bank credentials?
- matheusmoreira 7y agoI haven't posted them. The fact that data is private means I'm currently the only one in possession of it. It doesn't mean it's mine. Should they leak, the solution is to invalidate those credentials and get new ones, not to invoke copyright and try to get all copies off the internet.

- wayoutthere 7y ago> When will it stop? How deep run the flaws in Intel's platform? Is AMD equally exposed? We're seeing the tide turn from x86 to ARM pretty quick in both the datacenter and laptop markets. AMD should come through relatively unscathed as they're pretty diversified, but Intel is fucked. Graviton2 (Amazon's proprietary ARM stack) absolutely crushes x86 from a $/performance perspective, and there are plenty of other companies building 80+ core ARM chips. Combined with the persistent rumors that Apple is shifting the Mac to ARM along with Microsoft reviving ARM Windows are a pretty strong signal as to where the laptop / desktop market is headed too. x86 (and by extension Intel's platform) is definitely headed towards a more niche role in the computing landscape.
- anthk 7y agoARM is a joke on raw computing. Also, RISC-V will crush down ARM on servers once it begins to grow a little.
- wayoutthere 7y agoARM is shit compared to x86 for single-threaded computing; you're right about that. But ARM is great at the types of hypervisor-driven cloud workloads that most applications fit into. Most cloud workloads are limited by network latency far more than single-threaded performance. x86 will still exist for high-performance workloads, and companies will happily pay a premium where they need it like they already do with GPU instances. But I do think we'll see the vast majority of cloud usage shift to ARM over the next 5 years. RISC-V may come in and replace it some time after that, but not without major cost advantages over both ARM and x86.

- amluto 7y ago“utter chaos” seems overstated. I’ve never heard of anyone protecting DRM with the TPM on any consumer platform.
- thrtythreeforty 7y agoI read that part as slightly tongue in cheek. No, it won't be the end of the world, but it will be the end of the usefulness of that hardware.
- Avery3R 7y agoTPM, no. I'm fairly sure that PlayReady's HWDRM implementation does integrate somewhat with ME though.
- harrier 7y agoIsn't it required for 4K Netflix on Windows?
- annoyingnoob 7y agoSo ugly, I can't just replace all of our hardware. Remaining forever vigilant is tiring. CPUs are so broken that security is just a facade.
- rolph 7y agothe problem is the hardware being replaced to begin with. The ME is not needed for the end user to operate thier machine in a secure manner. The ME is a trojan that allows intel to manipulate your system and lock you into the whole DRM nonsense. the only reason Intel platforms havent become as bad as mobile platforms is because there isnt enough fear of system compromise from the average user. https://en.wikipedia.org/wiki/Intel_Management_Engine https://en.wikipedia.org/wiki/Intel_Management_Engine
- animalnewbie 7y agoYou know if your did less FUD there's a chance people may actually engage in a conversation with you. Anyone from enterprise knows his much of a timesaver amt is. I make a call andi don't have to wait for the IT dude to appear on my desk- he clicks a few buttons from his desk and my problem is fixed.
- RandomTisk 7y agoWhy do we need ME for that?
- gowld 7y agoActive Management Technology (AMT) is built on top of Intel ME. ME lets a trusted party control the computer without letting every peer control the computer.
- kelnos 7y agoI think the point is that all of this can be implemented purely in software that runs at the OS level, or even application level. There's no need to put this in a place where it's difficult to update/patch, and is entirely opaque and user-hostile to the point that the actual end-owner of the hardware can reasonably be sure they know what it does and can control what it does. In other words: I don't want a backdoor into my system that I can't examine or disable.
- mindslight 7y ago> This is used for things like providing anti-piracy DRM protections, and Internet-of-Things attestation "Internet-of-Things attestation" ?? A poor attempt to stick a refreshing buzzword in front of a fundamentally unwanted user-betraying open-society-undermining technology. Remote attestation does away with the basic foundation of protocols for mediating between mutually-untrusting parties, making it so users must trust the remote party. Imagine if websites attempting to enforce (browser fingerprinting, no image save, anti-adblock, etc) could successfully implement their hostile restrictions! This break is great news for everybody that wants their computer to remain under their own control, rather than an increasingly locked down Big Tech WebTV.
- matheusmoreira 7y ago"Piracy" is a buzzword too. Copyright infringement is a crime so victimless they feel the need to compare it to literal high seas piracy in order to make an impact. > This break is great news for everybody that wants their computer to remain under their own control, rather than an increasingly locked down Big Tech WebTV. Completely agree. This "security breach" is only bad for corporations who want to track users and implement DRM. It's great for the freedom of the people who are actually using the computers.
- dnautics 7y ago> "Internet-of-Things attestation" ?? A poor attempt to stick a refreshing buzzword in front of a fundamentally unwanted user-betraying open-society-undermining technology. While I agree with you at a consumer level, at the industrial level this is a thing. Like, imagine a vertical farm that is controlled by a thousand, networked on-prem robots. An "attestation" mechanism makes setting this up easier and less-error prone.
- mindslight 7y agoHow so specifically, compared to say just imaging the devices? Are we really worried about rogue employees putting rootkits on said robots, and to what end? Remote attestation in general does have positive uses, and would be freedom preserving if the signing keys were controlled by the device's owner. The problem is Intel's design of baking in privileged keys that they themselves control, such that hostile parties can require that you run software that they provably control.
- 6510 7y agoPerhaps it sounds dumb but when I buy something I want to own it. It doesn't seem all that legally complicated? After I buy a thing it should stop doing things for previous owners.
- tedunangst 7y agoHow many can there be? (Stories about the same issue, I mean.)
- eatonphil 7y agoThe labs team at work wrote a bit [0] about why this is over-hyped (more context in the full post): > Arbitrary code execution is bad! But exploiting this vulnerability requires local access at a minimum, compounded by the attacker needing to exploit a relevant device to gain a foothold on the system. This list of valid footholds is quite limited. For instance, an attacker would need to perform code execution in the ISH or other Platform Controller Hub (PCH) devices — exploiting PCIe devices (like GPUs or RAID controllers) wouldn’t suffice. Additionally, per the original blog post, other methods of exploitation require physical access. Either way, this is limited to incredibly motivated and well-resourced attackers (like a nation-state with a high-value target identified).

- nine_k 7y agoIt is limited to any well-monied adversary. So, every serious company should be concerned that their competition (maybe abroad) will be able to eventually decrypt a lost / stolen laptop with trade secrets. So every corporate laptop needs its full-disk encryption upgraded. It's large.
- gggmaster 7y agoSo this is a good feature for fighting against DRM.
- LargoLasskhyfv 7y agoSeems like something like these start to make sense again if you can live with the limitations: https://www.biostar.com.tw/app/en/mb/result.php?model[]=973&model[]=950& https://www.biostar.com.tw/app/en/mb/result.php?model[]=973&... should be under 100$
- hannula 7y agoSo it seems that the flaw can’t plausibly be exploited by a remote or adjacent attacker or software. So what’s the impact here? Warez scene wreaking havoc with lossless WEB-DLs?
- rolph 7y agoif intel can manage your machine state remotely [they can with ME] then someone else can as well. corporate customers often have an elevated relationship that retail consumers dont have. There is a different level of trust. I dont trust Intel. I didnt ask for ME and i treat any hardware with ME as an edge device. as far as impact is concerned its possible that clone machines could be manufactured with hardware modifications. how possible depends on how much money someone has to throw at the project. exploit chips could become a common offering all you need is a steady hand and a solder iron, and a blob of epoxy for good measure if you want to hide the job. if as a highminded attacker you determine the hardware key, as it stands you can then decode a software key and begin manipulating firmware. The concern being that the same hardware key is used accross all ME chipsets.
- ngneer 7y agoIntel cannot manage your machine remotely with AMT. Your IT department can. See Black Hat talk on ME for details. https://i.blackhat.com/USA-19/Wednesday/us-19-Hasarfaty-Behind-The-Scenes-Of-Intel-Security-And-Manageability-Engine.pdf https://i.blackhat.com/USA-19/Wednesday/us-19-Hasarfaty-Behi...
- kristofferR 7y agoA ton of warez groups (even a lot of P2P ones) already have a Widewine exploit that works for >=1080p anyway, some groups (BLUTONiUM, PETRiFiED ++) even have a 2160p exploit. It's actually quite amazing that the 1080p exploit hasn't leaked and been patched yet, considering how widespread it is.
- scenethrowaway 7y ago<=1080p content is typically only protected by code obfuscation. There aren't usually any "exploits", merely a moderately skilled reverse engineering effort - as such, nothing can be patched any time soon.
- pabs3 7y agoThis reminds me of the recent iPhone bootrom vulnerability, which lead to Android on the iPhone: https://checkra.in/ https://checkra.in/ https://projectsandcastle.org/ https://projectsandcastle.org/
- dependenttypes 7y agoThis is great. It might be able to be used by programs like me cleaner.
- pontifier 7y agoDoes anyone still trust their computers, or trust that secrets will remain secret? I certainly don't.
