Unfortunately, users don’t want to learn. They want the app to do what they want. Anything involving learning is likely to get an instant “screw this” reaction. Seen it firsthand many times, and always found it mystifying.

FBI used iPhone notification data to retrieve deleted Signal messages

Just to clarify, this is within the Signal app settings—not the OS (iOS or Android) system settings. Critical distinction, as merely changing OS notification settings will simply prevent notification content from being displayed on-screen.
Signal should switch the default to being less verbose.

The app decrypts the message and displays it via the system notification.
So in that case, the system has access to the plaintext, therefore the Alphabet boys have access to it as well. Unless, of course, you believe Apple isn't cooperating with them. Am I missing something here? Maybe I'm missing a subtle detail.
Re: FBI used iPhone notification data to retrieve deleted Signal messages
#274OK, maybe they can be stored until they're dismissed in case the battery suddenly dies, so they can be displayed again on next boot and are not lost, but it sounds like they are being stored long after they are dismissed.

#275Putting on my user hat... "OK. Signal has forward secrecy. So messages are gone after I receive them. Great!" Oh, you didn't turn on disappearing messages? Oh, right, then forensic tools like Cellebrite can get them. You have to turn on disappearing messages. The default is off. Oh, you did turn on disappearing messages? We send the messages in notifications. So the OS can keep them. Turns out Apple was doing that. T…

#276A lot of dumb criminals seem to carry smart phones. The irony.
Probably, but these are people who are being charged for political "crimes" brought mostly because the government doesn't think people have a right to protest. While it's unsurprising that the citizen who discharged their weapon was tried for this, most of the other folks were just doing run-of-the-mill protest stuff. I also get that in Texas they are fine "criminalizing" protesting, but that's just part of its hyper…

The Proton Drive app keeps asking me to turn on backups of photos and video. There is no option to say "don't ask again." I guess they /want/ more storage to be used? Or is there a support issue they are trying to deal with?
Yes Google constantly asks me to backup my pictures to their platform No, I don't want this. But regularly when I go to my photos it'll pop up with a box asking and the default option is yes please back up. Sad.

"end-to-end message encryption is a sham as long as" -- I agree with that but would add even more caveats. If someone can't list those caveats off the top of their head they shouldn't be pretending they aren't able to communicate securely. Just look at Salt Typhoon, every single person should be way more paranoid than they are, including government & agency officials. The attach surface and potential damage - financi…
Given the shoddy state of network security at large, especially on infrastructure projects (power plants, hospitals, dams, etc.) I always feel like major governments sit on so destructive potential to disrupt communications and anything connected to the Internet of its adversaries to have mutual assured destruction potential of a nuclear bomb. No one’s crazy enough to push that button, because once you do there is no…
Re: FBI used iPhone notification data to retrieve deleted Signal messages
#280Perhaps a stupid question, but why do notifications need to be stored in a database in persistent storage at all? OK, maybe they can be stored until they're dismissed in case the battery suddenly dies, so they can be displayed again on next boot and are not lost, but it sounds like they are being stored long after they are dismissed.
