Hello! Computers or websites can be hacked because someone made a mistake in coding or securing them. That can happen for the best, luckily ethical hackers are here to help detect those mistakes and share them with the makers. One of those common mistakes is when a person enters something that is not properly checked. A system then does not know what to do with the input or returns information that can be used to gain access to a system. That is why it is important to always consider what information someone can enter into your application. And to process this information properly by your website or program! Can you get a flag with the interactive program by using a coding flaw?
