People being hacked since the last Server Check.

If there was some hacker that was able to bypass logins, Nexon would know about it and shut down their game until it was fixed.

How exactly would they do that?
Would some programmer deep in the bowels of Nexon HQ's spider sense start tingling?
Would some great alarm go off somewhere?
Would God Himself Manifest before the office to explain to them what happened?
Will Gandalf The Gray Stand before the hackers and shout THOU SHALL NOT PASS as they try to break in?

A program only does what it's programmed to. Unless they specifically designed it to recognize that it was doing something it wasn't designed to, how exactly are they going to be aware that it's happening? The very fact that someone logging in this way is a bypass indicates it's something they didn't anticipate being possible, therefore how exactly would they have security measures in place to identify it was happening unless they went out of their way to add them in to try to identify them happening? Which would require them to admit it was possible in the first place.

You have no more foundation for your "couldn't happen" than the other side does for their "could happen".

There are a finite number of ways to hook into the keyboard input and most decent antiviruses can detect any process that is doing so, short of it being rootkitted because they don't need to know to listen for specific programs, they look for specific behavior and any process behaving that way is suspect.

So knock it off with all this bullpomegranate about some amazing hackers who are able to read the Nexon database and hack all of your accounts. Pay attention to what the pineapple you download, and exercise at least a minimal amount of caution, and you won't get "hacked."

This too is bullshit. Security is not entirely on the users side. Did the people with accounts as Sony download anything? No. Sony was breached. Assuming Nexon is immune to breach while larger more sophisticated companies are not is delusional. The vast majority of us who have been hacked did not download a keylogger, pure and simple. Blaming it on a trojan, a keylogger or the end user is a cop out. Yes the end user is occassionally responsible, and during normal 'hacking' almost exclusively responsible, but whatever has been going on with Nexon lately is clearly a flaw in their security for at least a substantial portion of the intrusions that are occurring. A keylogger would not explain accounts that have been untouched in years being opened despite strong passwords. A keylogger would not explain people who have common sense.
