When exactly did it become possible to write to "firm"ware without that kind of physical setup, anyway? And why?

[@nickwallette6201]

The promise: "We can add new features and fix bugs in hardware you already own." The reality: "We can sell unfinished products with the carrot on a stick of potentially being finished.. some day."

[@CyReVolt]

The flash parts that can be erased and rewritten in-system and from within the system are due to updatability. The physical extra parts make it hard for people to upgrade when there are already bugs in the firmware, which happens often. And yes, it is not as "firm" as the name suggests - especially with UEFI bringing a whole other OS on its own. Bryan Cantrill calls firmware the "software that is hard to get to". Anyway, secondly, part of the flash is used for storage, where user settings, EFI variables and such are stored, like volatile data from other platform components, like the CSME, possibly EC, ethernet adapter, etc..

Well, it is there to authenticate the bootloader binary. And they wrote it.

You can however sign a state you trust, to ensure that state hasn’t changed.

[@kellymoses8566]

It is perfectly reasonable and actually a good idea for a company to ship products with their trusted root key and use it to verify signed software upgrades.

"locking the system down like a Playstation", and maybe make money on the side with "signing services". Anyway, I found a writeup of the state of this approach from 2020 in "Communications of the ACM": "Securing the Boot Process: The hardware root of trust."

[@probablypablito]

Secure boot is super important, especially on mobile devices. On many Android phones (where it is called Verified Boot) it is often disabled when rooting the device. This means anyone with access to the phone can run any code they want, such as a bruteforcer for a PIN (assuming no hardware limiting) With it on, only updates/code signed by the registered private key can be used. This ensures that if someone steals your phone, your data & phone are fully inaccessible.

[@JamesR624]

@@probablypablito This is not perfectly accurate. Though they achieve basically the same goal as you mentioned, AVB and Secure Boot are two completely distinct thing: most Android devices don't support UEFI which is needed for Secure Boot. Also, all SB/AVB "guarantees" is that you don't execute a bootloader that hasn't been signed by whatever keys are enrolled on the device. Once you've executed that bootloader, arbitrary code can be executed by other means. It's not much about bruteforcing: with physical access, one could extract your eMMC and try bruteforcing from there (as I don't think the master key is stored in a "secure device", correct me if I'm wrong though). You *should* be expecting RCE exploits on your phone anyways if someone has physical access to it: the safety of your full disk encryption should not rely on the ability of the attacker to execute arbitrary code on your device. However, SB/AVB prevents installing and executing a rogue bootloader that would, for example, keylog the decryption password when user unlocks the device.

It's a bit funny to think of the computer, I started up with 40 years ago. The OS was in a ROM or EPROM and you had to replace the chip to change the OS.

[@jan_en_ik]

That is most cyber security. as long as someone doesn't have the key/password your safe enough but, if the secret gets leaked Pandoras box is opened.

[@throwaway6478]

Most encryption works by the keys not being known by everyone - that is, obscurity.

[@drdca8263]

@@throwaway6478No, “the adversary doesn’t know the keys” is *not* “security by obscurity” . “Security by obscurity” is when the security is based on adversaries not knowing how the system works, and is *specifically in contrast to* security based on adversaries not knowing the secret keys.

[@SBlazeable]

this isn't security by obscurity this is security by password authentication with a stupidly low amount of bits of entropy so it was easy to crack security by obscurity is when you use a reversible, simple cypher such as the alphabet +2 where A=C B=D and so on, or you hide passwords by checking the "show hidden files" box to unchecked or you take the first half and append it to the second half so ABCD becomes CDAB, THAT'S obscurity

[@Sylvan_dB]

Once you conflate "obscurity" with "secret" you realize that all security rests on a foundation of secrets, or obscurity.

Automation prevents human mistakes, but automation eventually breaks and when it does it reproduces the same mistake on every unit. This is an expected kind of issue. It will come back again some day..

I designed offline signing procedures for financial institutions. Damn if the devices are on the list, we might need to renew many of them (I'll physically destroy and blend them all) and get them re-audited by third parties >.> I'm also curious that Chromebooks' keys are safe. Those are securebooted linux.

DAMNIT! I ALWAYS do this. I come up with an idea as a prototype/proof of concept. Once I prove my hypothesis I pretty much shelve it. The last thing I worked on two years ago was an SSO dongle very similar to this YubiKey thing. I went super paranoid and used biometric - fingerprint - in order to access it. That way it had 2FA built in - something you are, and something you have. Your fingerprint is something you are - it's unique to you and nobody else can take it from you. The device is something you have, and it can physically be taken from you. Edit: Forgot to mention it was built around a Pico Pi for the prototype. Those are like $4 boards with a custom M0 Cortex chip called an RP2040 which is the microcontroller in the Raspberry Pi ecosystem. It can run MicroPython which makes writing the application code dirt simple and pretty safe as well. Writing native C can introduce memory bugs that could be exploited.

[@asificam1]

There is now a project developing an open source U2F dongle (part of what the yubikey does)... tricky part is getting a dongle that works U2F and SSH and GPG... and now they want us to use discoverable device resident crednetials called Passkeys which used to be called Password-less FIDO2 discoverable credentials. I dislike device resident creds for so many reasons including these dongles have VERY limited key storage space, and also U2F uses the same math and has same security as Passkeys but lets the host store a wrapped key (only the correct U2F dongle can decrypt the secret portion with its master key) which means they can be used for an unlimited number of logins on unlimited website (literally unlimited), but also an attacker with your key has to first find by trial and error which account that key opens and where... discoverable credentials are less good because the attacker now has the key and a list of what it opens... bypass the PIN (If one was set anyhow) and you're in.

[@mjmeans7983]

You can bet state actors aren't happy that someone is shining a light on a bypass that has existed for years.

[@Elesario]

Was mildly amused when it said DB database. Guess I'll put that one next to my PIN number.

[@virkony]

Just create a ring of root authorities owned by different entities. Require all of them to agree so even if one is compromised, you still can't bypass "the ring".

[@GyattGPT]

This kind of stuff is a problem with the culture that doesn't care about security. Probably at least a few dozen people knew that anyone on their team could easily grab a copy of the key, and did nothing about it.

[@davidf6592c]

Hey man, love your work. Important question, I stumbled on this video, the day before I got a gigabyte B450M delivered. I opened the box containing all the components for my PC build to find all the components were factory sealed, except the motherboard. Of course, after watching this video, I'm paranoid. So I enquired with the supplier and the Gigabyte local representatives as well and I'm shocked to learn that the boxes are not necessary "factory sealed". This just seems absolutely bonkers, the supply chain from the manufacturer to consumer have just accepted that it's ok for this low level (again, lover the channel 😉) and vulnerable component to not be sealed. I think you should dive into this with an investigation, and call it out.

[@GeorgeNoiseless]

Wow, Gigabyte is winning this one with the largest number and variety of compromised devices! Intel/AMD/ARM Server boards, full Rackmount Servers, Mini-PCs... At this point I'm downright impressed by Gigabyte's consistency in upholding their poor reputation.

[@not-underscore]

And windows 11 requires secure boot to be enabled 😂 So much for security ,no?

[@zzco]

lol shame on motherboard manufacturers for taking EFI test certs and reusing them blindly, lmao.

[@fatherfoxstrongpaw8968]

the only reason i clicked on your video from the youtube suggestions is to tell you what i've been telling all these suspense and cliffhanger titlers which is this. if i don't know what the vid is about, there's a 96% chance i'm not going to waste my time clicking on it. i really wish artists like you would quit wasting youtube storage space.

[@somesalmon5694]

People saying secure boot doesnt make anything more secure and that its a proprietary stack that the user has no control over don't know what or how secure boot actually works. The user can reset, remove or distrust whatever keys they want and create their own to replace the Microsoft and oem keys to have full control over which signed binaries are allowed at boot
