Years ago, hacking was a skill only limited to experts, hence, a limited number of people. These days, hacking has become something very common. There are even apps out there in the web that helps users become hackers. Though hacking is very common nowadays and some consider it as normal, hacking is definitely and will always be a crime. Here are some of the hacking apps that you definitely have to be aware of:
To use this app, one must be connected to Wi-Fi. Well, technically, at least two people. A good example is when you're connected to a Wi-Fi network and on the same network someone is trying to log-in their Facebook account, this app will hi-jack their account, giving you the power to use their Facebook account. So, be really careful in connecting to public Wi-Fi hotspots, because you never know how "safe" you can be from hackers.
This app is like what the FBI and CIA used to do (or do they still?). This app will tell the user how many devices are connected to his/her Wi-Fi network. It will also tell the user what are they browsing or doing. Yeah, if you're a parent and want to know what your child is browsing these days, it can be somewhat helpful in a sense, but can also be a form of invasion of privacy.
This app is like the Droid Sheep. As the user, you can hi-jack the WhatsApp account of the devices connected to the same Wi-Fi as you are. Yeah, so if you're pissed with those people who keeps stealing your Wi-Fi password, this app just like the Droid Sheep can teach them a thing or two.
This app has the power to hack a full-working website by sending SQL injections. About what SQL injection are, it is a code injection technique that is used to attack data driven applications in which nefarious SQL statements are inserted into an entry field for execution. Basically, in a sense, it sends a virus that can be harmful to the website.
