Key-logger alert!
We are currently dealing with a number of cases involving key-loggers and hacked accounts with ISK and items missing. As usual, the trail leads straight to ISK sellers. Doing business with ISK sellers is extremely risky as they will not hesitate to employ dirty tricks like this to get more ISK to sell. The best defense is to stay away from their websites entirely. We strongly recommend that players keep their virus protection up to date and do a complete scan of their system for security problems. If any are found, we recommend you change your password immediately.
