About 3/4 of the people I've known who installed Signal immediately left forever because someone they knew contacted them to say 'welcome' and they got super creeped out wondering how they knew they had joined. Their bull-headedness on zero options around it for years on end smells more suspicious than anything else at this point tbh. But I have absolutely no idea why they persist in this data collection. There's a lot to like about Signal's privacy, both in isolation and in comparison to other messengers. Which makes collecting that data completely ok (it's done securely now thanks to SGX!), because you should obviously trust Intel because CPU vendors have had such a fantastic track record in their on-chip security systems. The difference, which that article goes into, is that now they're going all-in on you also trusting Intel's SGX and thus every single thing in between you, them, their hardware delivery pipelines, etc. so you can just enumerate literally every phone number ever on a decent computer in a few seconds and, if combined with basically any other information at all (like an area code), that's enough to figure out many or most contacts trivially. Regardless of how you hash them, it needs to work on a phone, and it needs to be reasonably unique. if it wasn't accurate, it would have unacceptably many false-positives, so it's a necessary quality of the system). No, they're still uploading the same data as they did before (last I looked into it, it was still enough data to rather easily reverse and get pretty good accuracy. I remember finding my number listed many years ago as my name with (web developer) in parenthesis, likely stolen from some old customer of mine. When I need to use Trucaller I use it via their web interface exclusively with a google account that has 0 contacts for them to steal. Eventually the competition subsided and this reduced significantly to a point where it's not very common anymore per my understanding.

The 'Mobile Number Portability' system was eventually introduced that minimized this to a large degree. too.įor a number of years it was quite common for folks in the lowest income brackets to change their phone numbers quite often because of rampant competition between mobile network providers. It's common to see folks post their tax ID numbers etc on public forums, tweets, etc. Only a very tiny fraction of the total population is averse to sharing personal information like phone numbers. The vast majority of thinking here is not very sophisticated about these types of topics. Most people are unaware of this, or don't care since we are a third world country and privacy is seen as a first world problem.

When you install the app they steal your contact list and populate their database that way.
