I got an E-mail today asking me to authenticate a login attempt. I had not played GW2 all day.
The following location was specified:
Address: 112.98.67.52
City: Saerhtu
Region: 08
Country: CN
Saerhtu appears to be a city in China. Obviously I don’t know anyone in China since I live in the Netherlands, so this was obviously an attempted hack of my account. I have changed my password immediately, but I just wanted to report this here so the GW2 team can stop a threat.
