I guess enabling Lockdown mode might avoid this particular issue too, together with a bunch of other stuff?

Why would lockdown mode prevent this? I have lockdown mode on but that doesn't automatically make my notifications private.

Maybe it should.

Settings > Notifications > Notification Content > Show: "Name Only" or "No Name or Content" I've had this enabled to prevent sensitive messages from appearing in full whilst showing someone something on my phone, but I guess this is an added benefit as well.

Fwiw, in my Signal app on Android this setting is in Settings > Notifications > Messages > Show

My Samsung also keeps a history of notification content. Under Settings->Notifications ->Advanced -> Notification History

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.

> testimony in a recent trial Court cases are the real way to audit security. Larping about security and complaining about companies responding to court orders only gets you so far. Its way more useful to look at what actually happens in reality.

The recent Trivy / LiteLLM mess was also a security thing, and seems rather different.

It's a mode of the phone that is supposed to prevent cyber attacks, more so than "normal mode" I suppose, since it's supposed to limit features in the name of security. This seems like a variant of such attack, so seems like it should protect against it

However, if this is important to you then you want Signal to stop telling Android to make the notifications. If it doesn't exist nobody will accidentally make it available.

Deleting that history is good to know about after the fact, but preferably lets just not create the problem.

First, a critical setting for Signal users: "Signal’s settings include an option that prevents the actual message content from being previewed in notifications. However, it appears the defendant did not have that setting enabled, which, in turn, seemingly allowed the system to store the content in the database." Second, how can I see this notification history?

On android its quite easy. There is a page of a protocol address that has all notifications show. I used to have a shortcut to it. It has been years since I was on android.

But it was really useful each time I did not see a notification in time.
