in Egypt, every person is born with a universal national ID number , which is standardized everywhere here, but it created some problems, it became extremely valuable to attackers. If leaked, it can be reused across completely different services ( and you can never change it under anycase )

Having the full name + national ID was enough to bypass verification and activate various services, and many people weren't tech savvy enough to realize how dangerous it was to share or leak that info

Clearly it was the services that weren't tech-savvy using a non-changeable non-secret ID as some kind of authentication. Can't blame the users here.
