Well, by that time most likely it had leaked, Sirius told Dumbledore, we know that Snape and the Waesleys also found out at the end of book three, Harry, Ron and Hermione knew too and talk about it in school even though they attempt to use code and stuff.....
could just be random guess work, get Draco Malfoy to say it to Harry and see what the reaction he receives is and that would tell if the guess was right....
or maybe Snape leaked it depending on which theories about Snape you choose to beleive....
or maybe somebody was spying on them...I mean, Rita Skita managed to spy on people, how do we know that there aren't more like Rita Skita or Peter Pettigrew running around in unregistered forms spying on people
