Yes part of it works as you’ve suggested, the ID part.
However, there’s more at play. Somehow there is access to data about whom I contact (again only via iMessage) and the contents of messages (only via iMessage). It’s not an imagined correlation, some of the data shown on the app could only come from recent iMessages.
The names of the “people” it suggests to me are frequently names of people who I know. Somehow, whatever is generating fake profiles is inferring my identity and showing me names of people I know.
Amazingly, it seems to have access to iOS communication because sometimes I’ll imessage with someone I haven’t communicated with in a long time (by any means), and soon enough their name pops up on the other app.
Do you have any insight on how it might work? I’ve wondered if there’s a very common app that many of my contacts would have installed that is able to peek at iMessage.
