The hackers have been found.

It appears they use non-Korean numbers, so they must be doing something. Apparently they are using a complicated OS that looks like Windows, to confuse anyone who thinks they are hacking with complicated technology. Also they do most of their hacking with the mouse, as seen above, so they rarely use the keyboard.

Here is the main hacker. Note the complicated round device to randomly choose numbers and the explosion-proof portable case.

Here they are doing something very serious, with the mixing machine to decrypt the hidden messages in the Taylor Swift songs they illegally downloaded from Sony. They also have a landline phone for serious communications.

Here is another example of how they have mastered hacking with only a mouse. Very advanced.
