Signal leaked random contacts to me! (feddit.de)

When I press on some message to forward it, it shows me Random usernames of contacts I don't know. And it even shows some Mobile Numbers I don't know. For example, one number starts with +964 that's Iraq. I'm from Europe tho. These contacts and numbers are from all over the place.

Edit: This only happens on Signal Desktop. If I try to forward a message on Android it only shows my Contacts. And none of these unkown ones.

So Signal does not protect against those that fill their contacts with every existing number?

But also, this does not explain why is it only happening in the desktop app for OP

Protect against what? People knowing you have Signal? Excuse me if it's obvious to everyone else, but I'm struggling to understand the issue here.

It confirms that your number is valid and in use.

You can check that in the phone app too. Hit new message, enter the numer, hit "New message to... " and it'll tell you if it isn't known. There is rate limiting in that function, you'd need a lot of signal accounts to sweep all phone numbers.
You could also try signing up to signal using the number you want to check.

Neither way however you would get the signal name or profile pic of the number if I understand it correctly, that would get sent if they reply to you.
