My account got hacked as well. The other day, I too was asked to change my password. At first I figured it wasn’t a big deal, so I was able to change it. I tried logging in today and I wasn’t able to log in. I was forced to change my password again. By this time, I checked my email and it said that someone had authorized to log into my account at 4:26 a.m. (CST). Here is their info.
Address: 222.122.31.207
City: Daegu
Region: 15
Country: KR
A lot of my important materials for my professions are missing as well as gear. I hope Arena Games can help me recover my stuff or at least put a stop to this fake changing passwords.
