Many hackers like to give their hacking skills a work out. to them hacking is just a game of skill and test. They celebrate when they manage to hack a system. but like many people in the world, hackers are also bad and are not perfect. Some bad one will attempt to steal money from hacking your computer. overall many hackers hack just for the fun of it and become master computer programmers for a company.

A denial of service attack is a technique that hackers use once they have already gained access to an individual computer, or a larger network.

Unfortunately you will always have to worry about hackers. Faxing via email is a great idea and it is just as safe. You just need to use a trusted service that will help protect you against the hackers.
