No.034	Notice regarding the occurrence of fraudulent announcements in all worlds	2003.3.20 3:50


This is the Ragnarok Online management team. 

We have confirmed that on March 20th, from around 1:25 to 1:33, in-game announcements that were not made by the management team were made to all worlds due to unauthorized access.

We are currently investigating unauthorized access. Therefore, as a temporary measure, we have suspended the chat server function in all worlds. As a result, chat, party, and guild functions will not be available in-game , but there will be no harm in continuing to play the game. 

First of all, we would like to apologize for the inconvenience caused to our users. Although this incident is an unauthorized access to the game system, there is no unauthorized access to your personal information as it is a separate system managed by GungHo that is isolated from the game system.

Therefore, please rest assured that your personal information is safe. We will notify you regarding the restoration of the service at a later date.

GameSpot also made reference that AEGIS had been leaked, although it was not specifically detailed whether AEGIS was leaked in this hack or had been leaked before and had been analysed by hacking groups.

The group ApezRO themselves announced on their website (apezro.cjb.net) that on 19 March 2003, they celebrated "1 year of hacking RO". On the day of the hack, they posted an unrelated update, explaining that language filter files were available for GRFs.
