  • Those “personal pet projects” are why Google and FireFox exist as many pieces of their projects often rely on open source components often maintained by a single person.

    Those are a different kind of pet projects, like some small random math library developed by a guy in Nebraska that a big software stack depends on (there’s a relevant xkcd about it somewhere). The thing is, if support for such a project stops, the Microsofts, Googles and Firefoxes of the world are able to take over support, pay for it to be supported, or work around it in another way. Plus they are usually careful about which dependency they introduce, if something isn’t governed properly or does not have wide community support… it’s unlikely to be included.

    Taking on a whole browser as a pet project is something entirely different. Browsers are huge and complex. You’re basically betting that mr-cheffy will be able to keep up with all the changes, like security updates, feature updates and bugfixes, that upstream Firefox produces, and that he will be able to keep his own part of the codebase secure, and that he won’t get burned out or bored with the project in one or two years.

    For these reasons, I will never put all my eggs into the basket of some 1-man browser project, sorry.

    These pet projects also strip telemetry and respect your privacy.

    Turning off telemetry is just a few clicks, or about:config flags in Firefox anyway. And “respect your privacy” is just meaningless buzzword bingo. If you go to facebook or google in zenbrowser, your data is harvested just like everyone else’s. Privacy is a process not a product (browser).








  • with literally no other input needed

    Wait, you just let them put on whatever they can get the highest margin on?!

    There’s a vast difference between different tire types in terms of stopping distance, wet handling, wear, road noise, comfort, … When I walk into a tire place, you can bet I come prepared with a short list of tires that I’m willing to consider, and a pre-estimation of the price of those tires in my tire size.

    Also, the tire size is literally just 3 numbers, and it’s literally there on the tire. Why wouldn’t you know that about your car?








  • Second thing is, No, TPM+PIN does not help, the issue is still exploitable regardless, I asked myself this question, can it still work in a TPM+PIN environment ? Yes it does, I’m just not publishing the PoC, I think what’s out there is already bad enough.

    The PoC for that goes to another school, in Canada.

    Edit:

    Downvoters don’t understand the nature of this exploit.

    Without PIN, the windows recovery software has full access to the encryption keys in the pre-boot environment. So to crack bitlocker in this case, a hacker only needs to find a bug in the WRE to get at the keys. => That’s the Yellowkey exploit.

    With a PIN, no Windows or Microsoft program has access to the bitlocker encryption keys until the PIN is provided, and it can’t be brute forced because the TPM protects against that. To exploit that, would require a attack on the TPM hardware itself, which would be absolutely massive if he could pull this off through software only and of a completely different nature than the Yellowkey exploit. It also wouldn’t have anything to do with Microsoft software, because it wouldn’t be in the loop for this.

    To use an analogy: Yellowkey is like beating a bank employee (the WRE) who knows the combination to the safe with a wrench until he gives you the combination. In an attack with a PIN, the bank employee doesn’t know the combination himself, so you can beat him with a wrench as much as you like, he’s not going to give you anything useful.

    Extraordinary claims require extraordinary evidence, and he has provided none. Furthermore, he has a bone to pick with Microsoft over a denied bug bounty, so he clearly has a motif to undermine trust in Microsoft products like bitlocker. All this, and knowing the typical hacker personality, leads me to believe that this is pure bluff. If he had something, he would show it.





  • In many cases there’s no extra wear

    You can’t change physics. More HP = more torque = more wear on the whole drive train. Also more boost = more stress on the turbo = it will fail sooner.

    Also, back then, cars with the higher specced variant of the “same” engine almost always had mechanical upgrades compared to the lower specced engine: usually bigger brakes, a stronger clutch, and various other drive train components.

    So while in many cases you could chip your car without much immediate harm, you were definitely cutting into various safety margins determined by automotive engineers who know much better than you and me.
