lol at you for having no idea what's really going on here. After a brief glance, the story posted in the other thread (which this thread should be in) suggests one of two things:
1) They got hit with a keylogger/malware program that allowed an outside agent to hijack a player's connection and red-dot them while assuming control of the character. This is a computer security issue, depending on their browser of choice and how secure they had made their computer and browsing habits, this goes from player stupidity (opening the door to OP's comment) or really shitty luck because their security didn't catch it (OP is totally off base).
or
2) Somebody's figured out how to execute a man-in-the-middle attack on FFXI. That's a wee bit worrying.
