People being hacked since the last Server Check.

Then it is very likely there were other undisclosed ones. Unless they have a way to get into any account without even having the password or through other means we don't know of.

Until now, I've been constantly locking my account with the available methods (now there's the Hotspot Shield one) and changing my password at least once a month, and I wasn't (luckily) affected. So yeah. Maybe there IS a way to prevent it, afterall. Or it's just been luck.

What's the hotspot shield method?
I've been changing my password once a week ever since my world xfer mule got hacked.
