I have a 7950X, a pile of RAM, and an unfairly expensive RTX 4000-series GPU. The cursor occasionally hitches for ~400ms whenever doing things like opening task manager or resuming from the lock screen, so that checks out unfortunately.
With regard to my examples, WEI provides full confidence and stability in identifying the browser.
Relying on detecting browsers by differentiating between their features and quirks involves on having a large suite of checks to run, some of which might become incorrect as browsers change over time. It’s a maintenance burden, to say the least.
Firefox will probably survive if they bow and add WEI support.
I can’t imagine Google, Microsoft, and Apple opening themselves up to further monopolization scrutiny by trying to keep attestation restricted to their own browsers on their own operating systems.
Self-built or community forks are probably screwed, though.
And here’s a concern about the decentralized-but-still-centralized nature of attesters:
From my understanding, attesting is conceptually similar to how the SSL/TLS infrastructure currently works:
Each ultimately-trusted attester has their own key pair (e.g. root certificate) for signing.
Some non-profit group or corporation collects all the public keys of these attesters and bundles them together.
The requesting party (web browser for TLS, web server for WEI) checks the signature sent by the other party against public keys in the requesting party’s bundle. If it matches one of them, the other party is trusted. If it doesn’t, they are not not trusted.
This works for TLS because we have a ton of root certificates, intermediate certificates, and signing authorities. If CA Foo is prejudice against you or your domain name, you can always go to another of the hundreds of CAs.
For WEI, there isn’t such an infrastructure in place. It’s likely that we’ll have these attesters to start with:
But hey, maybe we’ll have some intermediate attesters as well:
Even with that list, though, it doesn’t bode well for FOSS software. Who’s going to attest to various browser forks, or for browsers running on different operating systems that aren’t backed by corporations?
Furthermore, if this is meant to verify the integrity of browser environments, what is that going to mean for devices that don’t support Secure Boot? Will they be considered unverified because the OS can’t ensure it wasn’t tampered with by the bootloader?
Adding another issue to the pile:
Even if it isn’t the intent of the spec, it’s dangerous to allow for websites to differentiate between unverified browsers, browsers attested to by party A, and browser attested to by party B. Providing a mechanism for cryptographic verification opens the door for specific browsers to be enforced for websites.
For a corporate example:
Suppose we have ExampleTechFirm, a huge investor in a private AI company, ShutAI. ExampleTechFirm happens to also make a web browser, Sledge. ExampleTechFirm could exert influence on ShutAI so that ShutAI adds rate limiting to all browsers that aren’t verified with ShutAI as the attester. Now, anyone who isn’t using Sledge is being given a degraded experience. Because attesting uses cryptographic signatures, you can’t bypass this user-hostile quality of service mechanism; you have to install Sledge.
For a political example:
Consider that I’m General Aladeen, the leader of the country Wadiya. I want to spy on my citizens and know what all of them are doing on their computers. I don’t want to start a revolt by making it illegal to own a computer without my spyware EyeOfAladeen, nor do I have the resources to do that.
Instead, I enact a law that makes it illegal for companies to operate in Wadiya unless their web services refuse access to Wadiyan citizens that aren’t using a browser attested to by the “free, non-profit” Wadiyan Web Agency. Next, I have my scientists create and release a renamed versions of Chromium and Firefox with EyeOfAladeen bundled in them. Those are the only two browsers that are attested by the Wadiyan Web Agency.
Now, all my citizens are being encouraged to unknowingly install spyware. Goal achieved!
But the real questions is, can we change them?
Imagine this:
A couple years back, I had some fun proof-of-concepting the terrible UX of preventing password managers or pasting passwords.
It can get so much worse than just an alert() when right-clicking.
A small note: It doesn’t work with mobile virtual keyboards, since they don’t send keystrokes. Maybe that’s a bug, or maybe it’s a security feature ;)
But yeah, best tried with a laptop or desktop computer.
How it detects password managers:
Unexpected CSS or DOM changes to the input element, such as an icon overlay for LastPass.
Paste event listening.
Right clicking.
Detecting if more than one character is inserted or deleted at a time.
In hindsight, it could be even worse by using Object.defineProperty to check if the value property is manipulated or if setAttribute is called with the value attribute.
Yep! I ended up doing my entire co-op with them, and it meshed really well with my interest in creating developer-focused tooling and automation.
Unfortunately I didn’t have the time to make the necessary changes and get approval from legal to open-source it, but I spent a good few months creating a tool for validating constraints for deployments on a Kubernetes cluster. It basically lets the operations team specify rules to check deployments for footguns that affect the cluster health, and then can be run by the dev-ops teams locally or as a Kubernetes operator (a daemon service running on the cluster) that will spam a Slack channel if a team deploys something super dangerous.
The neat part was that the constraint checking logic was extremely powerful, completely customizable, versioned, and used a declarative policy language instead of a scripting language. None of the rules were hard-coded into the binary, and teams could even write their own rules to help them avoid past deployment issues. It handled iterating over arbitrary-sized lists, and even could access values across different files in the deployment to check complex constraints like some value in one manifest didn’t exceed a value declared in some other manifest.
I’m not sure if a new tool has come along to fill the niche that mine did, but at the time, the others all had their own issues that failed to meet the needs I was trying to satisfy (e.g. hard-coded, used JavaScript, couldn’t handle loops, couldn’t check across file boundaries, etc.).
It’s probably one of the tools I’m most proud of, honestly. I just wish I wrote the code better. Did not have much experience with Go at the time, and I really could have done a better job structuring the packages to have fewer layers of nested dependencies.
Back when I was in school, we had typing classes. I’m not sure if that’s because I’m younger than you and they assumed we has basic computer literacy, or older than you and they assumed we couldn’t type at all. In either case, we used Macs.
It wasn’t until university that we even had an option to use Linux on school computers, and that’s only because they have a big CS program. They’re also heavily locked-down Ubuntu instances that re-image the drive on boot, so it’s not like we could tinker much or learn how to install anything.
Unfortunately—at least in North America—you really have to go out of your way to learn how to do things in Linux. That’s just something most people don’t have the time for, and there’s not much incentive driving people to switch.
A small side note: I’m pretty thankful for Valve and the Steam Deck. I feel like it’s been doing a pretty good job teaching people how to approach Linux.
By going for a polished console-like experience with game mode by default, people are shown that Linux isn’t a big, scary mish-mash of terminal windows and obscure FOSS programs without a consistent design language. And by also making it possible to enter a desktop environment and plug in a keyboard and mouse, people can* explore a more conventional Linux graphical environment if they’re comfortable trying that.
Ah, that’s fair.
I’m having the opposite experience, unfortunately. I loved working at {co-op company} where I had a choice of developer environment (OS, IDE, and the permissions to freely install whatever software was needed without asking IT) and used Golang for most tasks.
The formal education has been nothing but stress and anxiety, though. Especially exams.
Did the formal education before the job ruin it for you, or did the job itself ruin it?
Would absolutely love for Serif Labs to create a port for Affinity Photo and Designer. Of the programs I’ve tried, those two have the closest UX to Photoshop and Illustrator without the software-as-a-service model.
Hell, I’d even take it if all they did was support it working under WINE. While I would prefer a seamless UI that fits in with both GTK and Qt, it’s understandable that they might not consider it worth the effort.
If that were the case, wouldn’t the mouse jump when the latest frame is presented? For me, it’s more that it just stays still until after Windows stops having a fuss.
