We are aware of recent reports regarding targeted phishing attacks that have resulted in account takeovers of some Signal users, including government officials and journalists.
-
These attacks, like all phishing, rely on social engineering. Attackers impersonate trusted contacts or services (such as the non-existent “Signal Support Bot”) to trick victims into handing over their login credentials or other information. To help prevent this, remember that your Signal SMS verification code is only ever needed when you are first signing up for the Signal app.
@signalapp this might be worth a push message to all users
-
To protect people from such phishing, Signal actively warns users against sharing their SMS code and PIN.
We also want to emphasize that Signal Support will *never* initiate contact via in-app messages, SMS, or social media to ask for your verification code or PIN. If anyone asks for any Signal related code, it is a scam. We make this clear when users receive their SMS code during initial signup.
Hmmm, and what about the monthly reminder to enter the personal smartphone code? How to differentiate this from the other?
-
@signalapp how to move signal account from a phone to an other? just a question.
-
While we build robust technical safeguards, user vigilance is ultimately the best defense against phishing. We will continue to work on mitigating these risks via interface design and signposting throughout the app. In the meantime, please stay alert, and never share your SMS verification code or Signal PIN with anyone.
@signalapp recipients who are not native English speakers may not notice the giveaways in this and similar scams.

@unaegeli @signalapp My guess: the reminder is a pop-up dialog. It's not a signal message, email, or text.
I, too, would like to hear Signal's answer to this question.

@unaegeli @signalapp I was just thinking of this.
It sounds like Signal is fairly unique in this setup. We're constantly being bombarded with verification requests, and it can be easy to forget one app works differently.

@signalapp you dum dum you just publicly shared it
"in a stunning development today, a random mastodon user showed they were able to take over Signal's Signal account. details of the hack remain unclear"

We are aware of recent reports regarding targeted phishing attacks that have resulted in account takeovers of some Signal users, including government officials and journalists. We take this very seriously.
To be clear: Signal’s encryption and infrastructure have not been compromised and remain robust. These attacks were executed via sophisticated phishing campaigns, designed to trick users into sharing information – SMS codes and/or Signal PIN – to gain access to users’ accounts.
@signalapp nobody should use Signal

@Lizette603_23 @signalapp Please stay kind and on topic, alright? Signal is open for feedback in their Discourse Forum.

@signalapp These attacks wouldn't be possible if you stopped requiring phone numbers -

Thank you for pointing this out

@signalapp "SMS codes" sounds like a you problem, though.

@signalapp Since Signal always asks for a PIN code for backups, it seems logical that threat actors are exploiting this behavior to trick users.

@solitha
I mean it's hard for some non technical users to make them understand what is the "trusted context" and what is not I suppose?I mean we had that with mail for years, people should know to check the senders mail, yet still Phishing attacks are often successful.

@signalapp You know how you could solve that? Stop taking users' phone numbers, and especially stop using it for verification. EZPZ.

You should add the ability to sign up with email. I'm not sure that Russian users can log in with a code from SMS.

@signalapp
Thank you for explanations.1. When will mere users be able to detach Signal session from the mobile device?
This single functionality (doable for versed hackers but not for the general public) would stop such scams for high value targets like journalists, who would simply use a single-purpose wifi only desktop/tablet.

@unaegeli @signalapp One is an in-app prompt. The other is a message, text or email. They don't look anything alike.
