Recently, I went on a cyber camp residential and learnt how easy it is to hack into computers.

Under a controlled environment, we hacked into one of our fellow teams computer. With this we were able to open up a conversation between the victim and the hacker, make random lights on the keyboard flash, make the mouse go crazy and open up unwanted tabs.
We also learnt how to change the users password whilst not being logged into the computer and we made our thumb print with latex to use to hijack our phones finger sensor ID.
We got taught why to keep ourselves private online through a demonstration of having a picture of a Yellow Lamborghini, and having to find out who it belonged to and other facts about them. It was surprisingly easy to find out who the person was and their age etc. all through looking at one picture.
