body: My university(and many others in my country - South Korea) takes course registration online. The thing is, the competition to get good classes is extreme, and it's on a first come first served basis. Good ones fill up within 1~2 seconds.  
  
  There's a javascript console exploit I have found out(for non-IT experts, this is just client side. That is, I am not "hacking" nor doing anything destructive) that allows me to register for all 7~8 classes in less than 1 second. This is basically undetectable from the school's server admin. There would be 0 problems for me using this method personally.  
  
  Now the problem is that I want to sell this method. I'm thinking about selling it like a "private hack" that isn't really an illegal hack but an exploit to 15 people for $150 each. It won't be a malware nor any form of software. It will just be some lines of code for people to put in chrome's console. This will most definitely stir up the hornet's nest, and it will probably be on the radar of my school.  
  
  Would there be a way for my university to prosecute me or penalize me for this?
