“The developers of TERA were immediately made aware of the vulnerability and they are exploring an appropriate course of action with the highest urgency,” the studio wrote this evening. “While they do so, the team at En Masse is continuing to investigate and assist the developers in any way possible. There are very serious claims floating around of what this vulnerability potentially allows malicious users to do. We are taking these claims very seriously but, as of this time, we have no evidence that the vulnerability is being exploited in these ways or that any player information has been compromised.”
The post is closed, and En Masse doesn’t give guidance on how players should proceed, only requests that players with helpful information PM the staff on the official forums. Reddit, meanwhile, has gone into meltdown, sending dire warnings to each other not to log in or make use of proxy services in the meantime, though that may be moot as the servers are being taken offline for “exceptional maintenance.”
We reached out to En Masse early this afternoon and still await reply; we’ll update if the response differs from the one on the forums.
