Telegram is giving away FREE Premium subscriptions! All they need from you is to use your cell phone as a relay to text out their OTP codes! And the recipient of the OTP sees your phone number! What could POSSIBLY go wrong with this deal?
PLEASE don’t use Telegram! I personally recommend Matrix as it’s totally FOSS, you can self host, there are tons of front end clients to choose from. Or even use Signal. I have my own issues with Signal, the fact they don’t allow third party clients, you can’t self-host, they have a proprietary shim in their stack that only they know what it does, they were pushing crypto, etc, but at least Signal is better than this garbage.
I’d be interested to hear people’s thoughts about Signal and DeltaChat for messaging
Signal is fine for a drop-in WhatsApp replacement. I use it for chatting to my friends casually. For something you need more security for you could do encrypted emails as that doesn’t require exchanging phone numbers, or ideally just arrange to meet up in-person and discuss things so you don’t leave any kind of digital or paper trail.
Yes, meet up, place your phones on the table, and discuss 👍 Facebook ads won’t change at all 😉
Obviously you don’t have your phones on you. Otherwise what’s the point of meeting up in person.
You don’t use your phone outside of the house? I must be the only one then. My bad.
Not if I don’t need to, like if I need to have a conversation with someone that doesn’t need to be overheard. In any case turning your phone off and putting it in a faraday bag then putting it somewhere relatively noiseproof should be more than enough if you need to bring your phone with you.
Sounds like something everyone does for sure. When I sit in public transport or go out to eat, nobody has their phone one them, and if they ever do, it’s safely tucked away in a faraday cage 👍
What could POSSIBLY go wrong with this deal?
No jokes, I’d like to know. How is it different from sending sms to random numbers?
… people just send SMS to random phone numbers?
No but what exactly stops anyone from doing that? A privacy consideration? I’d think it’s just a waste of time at best.
The issue here is that you could potentially read the content of a 2FA sms that wasn’t intended for you. It makes it easy too break 2FA if you have many devices
Logic suggests OTPs are locked to login sessions of corresponding users and also expire. Besides telegram would be able to tell if OTPs meant to be sent through you tend to not reach the recipients.
Yes but you can login on an account and hope you will be the one selected to send the code
You mean you can try to guess someone’s number before they get an OTP through you in order to be the first to log into their account?
Well then you’ll also going to need their cloud password in order to find anything worth of your effort.
But anyway this is an improbable scenario, considering how vast the user base is, and if we assume telegram implemented some precautions.
Malicious service providers and cloned sim cards pose a much more serious risk if you ask me.
