I haven't read the novel fully yet, but up to where I've read (somewhere in the 200s) only a select few people know. And those who know not everyone found out at the same time.

Spoilers?











Sayoung knew about it after meeting Eui-Jae for a few times but it won't be revealed until some *spoilers* happens while Eui-Jae was investigating about Prometheus. Even after that, not many people knows he's J. It's gonna take a while even for a selected few to knows about.
