I can't imagine any messenger is private if you invite random people into a group chat 🤦♂️
Layer 8 security issue
error: problem between keyboard and chair
but nowadays maybe it works better with screen
PEBCAK Problem Exists Between Chair And Keyboard!
Knew of an IT help desk employee who used this as a resolution in a ticket. Yeah, he got fired as soon as the customer looked up what it meant.
Also known verbally as an "I. D. Ten T." error (id10t error).
The actual military grade (xmpp based) messengers implement security lables, meaning messages are tagged with the required security clearance and if you invite random people to a chat they can't see the messages.
EVERYONE SHOULD DOWNLOAD SIGNAL for PHONE-NUMBER-based communication, tho. Proper RCS is not here yet (and won't be in a long while), so let's try to mobilize people to Signal.
DeltaChat is cooler for non-phone based communications, IMO, and decentralization makes it way sexier and worth this tradeoff.
Actually RCS has encryption in the new spec now, and we could see encrypted RCS messages implemented on iOS and Android within a year.
But even so, use Signal.
RCS still leaks metadata like a sieve. Encryption, considering the platforms that exist today (Signal and SimpleX), should not be the minimum requirement. Plain-text messaging should not even be possible in modern secure messaging platforms. The platform should be open source and be engineered to mitigate the collection of metadata - like Signal and SimpleX.

The exact reason why it's bad for top secret communications is why individuals should use it or something like it. That is government auditability.
Signal is the place for top secret communications, but not for any government business, top secret or not (at least not when using a public instance - they could fork the project to keep decryptable records on gov servers where the official gov instance would run).

All the people in the chat were high enough that the government for free provided them with secure rooms in their homes so everything would be done through government hardware and encryption programs.
Yes, ofc, using Signal was intentional to not keep any records/evidence.

The protections for classified information are not just about information security. They are about physical and operational security as well. That's why s SCIF has a "two locks" policy, and requires things like 4" steel doors.

What kind of private communication can we talk about if you must have a valid phone number to use Signal?! Lol
Signal recently implemented "usernames" instead of phone numbers
But still, to use it, you need a phone number, which in many countries can only be purchased with a passport. That's the main rule. If privacy is really needed, personal identification should be excluded so that it's basically impossible to determine who owns the account.
Pretty sure you still need a phone number for an account, though - the usernames are just for sharing your contact with other people.
Most peoples' phone numbers are easily linked to their identity. Which means the government knows who's using Signal.
Usernames are definitely an improvement, but this is a fundamental limitation in Signal's design.

Privacy != anonymous
No, but it's easy enough to be both. There's a pile of IM packages out there that manage it.
Metadata is valuable info, look at what a pen register nets law enforcement and why it's the first step in an investigation. The idea that a messaging app that's supposed to be used for political action but the chain of association is visible and verified is absolutely suspect.
You say "easy enough" but there are some serious tradeoffs when removing phone numbers from the equation. My mom can use Signal without my help but she wouldn't be able to use SimpleX.
Signal is a fantastic middle ground messaging app that is secure enough for me to use and easy enough for my mom to use.
I also have SimpleX but I have exactly 1 contact there...
Wherever Signal is mentioned, I shall mention SimpleX-Chat.
Zero user ID needed to use. No phone numbers and no username.
SimpleX-Chat!!!
Out of band key exchange is great -as long as people can physically meet and exchange QR codes. In reality, they are often sent via less secure means. As always, the humans are the weakest security link.
Fair point, it always feels dirty to send invite-link through WhatsApp, the dominant messenger in EU.
How would one go to solve the invite problem? How does Signal handle this?
Phone number and trust-on-first-use for most people, with out-of-band fingerprint verification for the paranoid. It really depends on the threat model and the security practices/awareness of your colleagues, but a link shared on some social media or lower-security chat network is more vulnerable to a man-in-the-middle attack than a phone number for your average Joe. There are a lot of ways a person could get a manipulated invite link.
Finally someone who understands! Haven't found anything better. Just missing the bridging bit, though that comprises the privacy/security and overall personal opinion why I started using SimpleX.
UI-wise it isn't there yet, but actively being developed so. I miss posting photos (combined) with a comment, now they are all sent separately.
Anyhow if you are looking for privacy go for SimpleX!

Consider Briar.
Uses Tor. Works directly over Bluetooth/WiFi if the internet is censored or shut down. Decentralized, no accounts. No phone number required.
Of all the options available, I feel like this one is the best suited to current threats (oppressive governments with all-encompassing surveillance, and the willingness to destroy critical institutions and infrastructure).
The app is super barebones right now - feels like SMS - but it works. Main downside is that both participants have to be online at the same time (maybe group chats can work around this?), since there's no servers.

Considering the US government now owns Meta and thus WhatsApp, it’s an interesting case… why did they use signal?
because "they" don't trust the people they "represent" and they want to avoid federal archives
they must know something about WhatsApp that we don't
There's nothing to know; facebook is facebook, and nobody trusts facebook for data security. Whatsapp is not, nor will it ever be, true end to end encryption, when facebook owns the locks and keys.

Signal is great, that's why I'm suspicious that this recent story is to not only target journalism, but also secure app communication. I wouldn't be surprised if it's used as an excuse to remove signal from the app stores.
Hopefully I'm just being too paranoid.
Immediately had that thought as well.
Don't blame the barn for not holding the horses when you leave the fucking door open.
I don’t think that’s the case, I just think it is old people not know how to use technology.
Additionally, all these people in power are using signal, how is that not a loud endorsement that everyone should be on it.
Sadly, my contact list remains mostly on WhatsApp and Facebook messenger only.
Anyone who uses Facebook messenger as their only messenging app will need to text or call me. Fuck that. I do, however, use WhatsApp and discord for work and uni group chats. If or when that's no longer the case, people who only use those will need to text me, too.
