Ethical hacking is when we study the techniques and tools of hackers. Hacking will not ever be allowed, even if you are allowing your friend the website they are hacking will not know that is your friend and think that it is just a general hacker. The most likely hack is an attack on passwords that are weak. With passwords are useful to hackers as when combined with other personal details such as names, birthdates or email addresses, the hacker will be able to get other account details. When they have one password for an account it is run through other your accounts and this is what might make your details vulnerable. If you put a password into one account and that company gets breached your password then can be taken from that company and hackers will have access to that information.
