It also amazes me that people are using the internet w/o an adblocker in the year 2025

I haven’t bothered working out how to install one on mobile. I just don’t visit websites with shitty ads.

Just use the Brave browser. No plugins necessary.

I see a lot of discussion in this thread stemming from some confusion+not reading the actual report[0]. Some key points: 1. The Camera+Card was encased in a separate enclosure made of titanium+sapphire, and did not seem to be exposed to extreme pressures. 2. The encryption was done via a variant of LUKS/dm-crypt, with the key stored on the NVRAM of a chip (Edited; not in TrustZone). 3. The recovery was done by transp…

If the encryption was that easy to bypass, was it worth it at all?

It continues to amaze me how indestructible SDCards are.

It's a solid piece of silicon encased in epoxy, so there's nothing really to get crushed. Contrast this to something like a cellphone that's made of hundreds of separate parts and has void space that will get crushed.

This comment made me wonder how much easier proximity fuzes would have been to develop in WW2 had they had transistors (or integrated circuits). I assume making modern solid state electronics 20,000g shock resistant is much easier than doing the same to vacuum tubes.

Why isn't a cellphone filled with epoxy?

> Why isn't a cellphone filled with epoxy? Added cost and weight are two things that would put off consumers. The phone would also be neigh irreparable, but consumers don't seem to care for that other than replacing their screen.

Neigh?

Unless I misread the article, the key was stored in the NVRAM and not the TrustZone.

IIRC, the article stated that if the key(s) had been stored in the TrustZone then the data would have been irrecoverable.

use pogo pins or a board to board connector

Which means air space that can get crushed. Either the phone is solid or it isn't.

> Which means air space that can get crushed

Would note that air isn't the only substance in a phone that compresses under 38 MPa. (Batteries come to mind.)

A conformal coating isn't "filled with epoxy", which is the concern I was answering.

There is very little empty space in a phone, so conformal coating is practically the same as filling it. Anyway, I wasn't disagreeing, just reasoning a bit further.

No, conformal coating and potting are extremely different things done for different reasons.

Firefox on mobile supports uBlock Origin

On iOS, every browser is required by Apple to use WebKit. I just tried it again myself and FireFox on iPhone has no ublock Origin add on possibility.

Firefox Focus does work as an alternative.

Apple created a special system-level API for Safari Content Blockers. Apps like Firefox Focus, AdGuard, 1Blocker, Wipr can register filtering rules with Safari using this API. That’s why Focus can block ads/trackers inside Safari if you enable it under Safari

So that's the next phase of making devices thinner? /s
