The war on encryption is dangerous

Government demands to access encrypted data via back doors will leave it vulnerable to hacks, breaches and theft

@signalapp i'm going to be a replyenby here for a sec

you do realize anonymity is a friend of security, and you're actively sabotaging your users' anonymity with your hard phone & phone number requirement?

you've built a great app but that choice of basing your account system on phone numbers makes it nonviable for the sensitive activities encryption is most nessesary for

@soop hello, I am a person from a Middle Eastern oppressive hellhole that executes and jails any political dissent online. So I know exactly how important it is to maintain privacy.
I think requiring the phone number for registration is an acceptable compromise that does not affect most people on the planet. Especially after rolling out different ways to connect such as links/QR codes and/or usernames, it became very viable to use under a high threat model. There is more to Signal that could clarify my position as well: https://signal.org/blog/private-contact-discovery/, https://signal.org/blog/sealed-sender/, https://signal.org/blog/signal-private-group-system/ among more.
Case on point? Compare Signal with SimpleX. The tradeoffs are clear.
Technology preview: Private contact discovery for Signal

At Signal, we’ve been thinking about the difficulty of private contact discovery for a long time. We’ve been working on strategies to improve our current design, and today we’ve published a new private contact discovery service. Using this service, Signal clients will be able to efficiently and s...

@soop The phone number requirement exists to prevent spam. You don't have to share your number with your contacts though, that's why user names exist.
@Andromxda @soop the addition of usernames is the thing that makes signal viable for use among people who aren't my immediate friends and family, although I still use it primarily for that purpose. An architecture like Matrix or xmpp where it's username@domain and you just sign up for it like any old thing is still preferable although doing that will also controlling for spam is a task needing a solution
@fluffykittycat Matrix is full of spammers. XMPP (in my experience) was able to avoid spam, due to just being obscure and irrelevant.
@signalapp @Mer__edith what you need is to #decentralize and #GTFO out of the #USA, unless you are a #StingOp like #ANØM...
@kkarhan if they were a sting, the code wouldn't be open source
@signalapp @Mer__edith

@ckrypto if@[email protected] wasn't complying with #CloudAct, @Mer__edith would be in jail.

Not to mention even if Signal keeps their "#OpenSource" code updated - which is doubtful, NOONE can actually #verify that it's the code you actually use - regardless if #backend / #Server or #client / #App!

  • #Signal is as secure as #ANØM, otherwise it would've been shutdown ages ago.

Also if Signal was designed for #security, it would've been #decentralized as #XMPP+#OMEMO and not demand #PII like #PhoneNumbers which oftentimes cannot be obtained anonymously in many juristictions at all!

By comparison, @delta doesn't require any PII, only an #eMail account, and @monocles isn't a #VCmoneyBurningParty but sustainable due to #subscription and they don't even require any personal details for #payment: #CashByMail and #Monero are accepted.

Again: It's Signal alone who have to evidence they are trustworthy, and all I get are "#TrustMeBro!" replies, which means they are not to be trusted.

  • Not to mention, it's just not sustainable to run a #service without #revenue, even if it's run entirely by unpaid volunteers and gets all it's #hosting and #costs donated, someone has to pay for expenses due to #abuse of a service (which is an inevitability come mass adoption)...

Whereas with #XMPP I can completely setup my own server and client, even build my own if I don't trust anyone else and pay someone to audit the code.

Whereas with XMPP & PGP/MIME #eMail I can layer @torproject / #Tor over it, make it an #OnionService and keep that thing under my bed with a literal killswitch...

@meles @signalapp @Mer__edith

Security and privacy aren't the same thing. And no, that's click bait. It is a company doing scraping of publicly accessible data, so it is unrelated to the security or privacy of either Proton or Signal. Please do more research before you make such wild claims.

@unexpectedteapot @signalapp @Mer__edith

I wonder what data from a ‘secure’ app should be public data. Is user data public data or are the messages exchanged public data or what else?

@meles @unexpectedteapot @signalapp @Mer__edith There is no public data on Signal, technically, though if a number is registered, and a user hasn't turned on the setting to hide their number from being searchable in the app, then their number is "public" to other Signal users. But just having a number to search is useless without additional information, like a name. See https://signal.org/bigbrother/.

@Avitus @unexpectedteapot @signalapp @Mer__edith

So you mean the ICE contractor ShadowDragon is wasting resources pointlessly to get data it can't do anything with?

@meles @unexpectedteapot @signalapp @Mer__edith Yes. As shown at https://signal.org/bigbrother/. Signal doesn't collect any data except phone numbers for registration, the date the number was registered, and the last date and time the account connected to the service. Everything else is end-to-end encrypted by default.

@meles
Have you even read the thread and the article? Only problem is the phone number. Other than that there's no concrete security problem.
@signalapp @Mer__edith

@signalapp @Mer__edith
Yes but you are still not Open Source and de centralized. Or usable without Phone Number.

I need to have this for full offline apocalypse, zombie and Doomsday Mode, to trust you my dairy.

P.s. I still love what you done so far. However, every chat got unencrypted and exploited by Apps and advertised on Apple and Google devices with its A.I. ... privacy bank rubbery.

@ibrahim_cris I don’t know about all of these things, but Signal’s source code is open source and freely available on GitHub. This includes its Android, iOS and desktop apps, as well as its server code and underlying encryption library:
https://github.com/signalapp

It also has regular security audits from third parties:
https://community.signalusers.org/t/overview-of-third-party-security-audits/13243

The last one was done on February 18 and found no vulnerabilities in Signal’s encryption:

I hope this information is useful!

@chriswood Server Code too?

@ibrahim_cris @chriswood https://github.com/signalapp/Signal-Server
I'm not sure where the whole "signal server isn't open source" came from, but it's not accurate. If you're so inclined you can roll your own signal infrastructure, though getting an app past Apple and Google's gate keeping would be an issue.

If you're threat model is so extreme, give Veilid or Reticulum a look.

@signalapp @Mer__edith thank you for all your work! So glad to donate to such a bad-ass not-for-profit and to have a safe space to talk to my friends and family 💪

@schm43cky @signalapp @Mer__edith

So, then I take it from your words in conjunction with the fact that the ICE contractor ShadowDragon is grabbing phone numbers from Signal and using them (presumably to merge with other data) that the use of Signal is contributing to attacks on the privacy of its users.

@meles @signalapp @Mer__edith Well what can they potentially acquire? The information that a certain phone number is linked to a Signal account. Plus maybe when an account signed up and when it last connected to a Signal server.
I don't know if ShadowDragon really can access these data though.
Sure, any data point can be potentially problematic.
But if you're that sensitive you might as well not use your day to day phone number for Signal registration in the first place.

@schm43cky @signalapp @Mer__edith

Now it's official: using #Signal is NOT safe.

@meles @signalapp @Mer__edith

```
A Signal spokesman said the Pentagon memo is not about the messaging app's level of security, but rather that users of the service should be aware of what are known as "phishing attacks." That's when hackers try to gain access to sensitive information through impersonation or other deceptive tricks.

"Once we learned that Signal users were being targeted and how they were being targeted, we introduced additional safeguards and in-app warnings to help protect people from falling victim to phishing attacks. This work was completed months ago," said Signal spokesman Jun Harada.
```

@meles @signalapp @Mer__edith Same reasoning applies to any other app, service or system.

This is a warning against phishing attacks *on a person*.

Once a person was incautious, impatient or incompentent enough to let some random QR code on the internet capture a part of its communcation stack, the underlying infrastructure (here: Signal) can't do a lot about it.

Maybe the linked devices feature hat a flaw in this regard (not enough bling bling?) but that seems to have been mitigated, as the article states.

@signalapp @Mer__edith cryptography is protective, and it's not just random hackers after my bank account I'm worried about it's the Nazi government
