In a message posted on the Trion Worlds website, the company promises that it is both researching the intrusion and taking steps to increase security. As part of this, all RIFT players will be asked to change passwords and security questions, and their mobile authenticators will need to be reconnected.
The company urges customers to watch their bank statements for questionable activity, and provides customers with resources to get a free credit report and putting a freeze on credit reports.
To compensate customers for the issue, Trion is providing all RIFT players with three extra days of gaming time and a Moneybags' Purse that increases all money looted by 10% in-game.
