People being hacked since the last Server Check.

NO! You're wrong, a PIC bypass is a security breach, yes, but if the people weren't keylogged it wouldn't have mattered, you know?
and you are missing my point; The players have already been keylogged, but the hackers couldn't do anything about it up to the point they obtained that PIC bypass, so you saying "a mass keylogger alot of maplestory players have downloaded" is a complete false statement, it didn't happen over night

I hope you know it's actually a rare occurance that players who are hacked are actually keylogged. And I would argue you that an updated virus protector would have little to no effect. In fact the last hacking wave wasn't even about keylogging, it was about finding your email address and bypassing the password by means of social engineering.

I mean it's not like hackers magically found a javascript on a site that all these users have gone to and forced them to download it.
