[Complete] Unscheduled Maintenance - May 3, 2013

Maryse from the Nexon forums. Man, I thought I got the wrong person but here you go:

Wait, they did what!? I would like to say that's fantastic but that's more scary than anything else. @_@

Ah alright, Maryse is fine she was just trying to calm down the thread.

To explain what likely occurred today. There are hundreds of commands inside the MapleStory client that are normally only known by Nexon staff. While most of these commands can not function without an "admin flag" (meaning the command handler internally checks if you're an admin, if not nothing happens), there are still dozens of commands that can be used by any player which allow for administrative controls, including setting server-sided functions to players. The player in this case likely knows how to access these commands which is easily done if you know how, and found how to parse it correctly. He's basically connected the character information window to a function that makes any "infected" player run a function to change the player's character class to 4th job Phantom.

There are many other reasons for this happening, although because of the likely high level hacking that was needed to accomplish this, it worries me that if Nexon does not make a massive effort to effectively remove all un-commented commands or add more checks to existing commands, that more harmful actions can happen such as making clicking a character give someone a permanent ban.

Hopefully there will be another maintenance, if not I honestly forsee this getting really bad. Players will continue to infect each other until there is a major need for a rollback.
