Any recent hacked accounts from Southperry users?

1)The nexon database is somehow ordered according to the date the account was created.

Obviously

2)There's only one person or a small group of people doing this systematically. If they sort of go in order, that means they're organized.

We can't be certain that this is true, but it does seem realistic. From this information, we can assume that accounts before this area of time are safer- you can't assume you won't be hacked, but there's less of a chance. Don't let down your guard yet though, because either this is just a coincidence or they might double back for any accounts they missed.

The general way of doing such things is simply using hash crack attacks on the whole database in order to parse the passwords, but it's very well possible that the hackers read the "parsed" database from top to bottom (older to newer accounts) for organizing reasons. It's not like you can predict who's going to get hacked next, because you don't know which hashes did they manage to crack by now. The hackers aren't obligated to go by regular order either, they are probably just doing it because it's easier to know which accounts are already hacked this way.
