Think you have a good knowledge of internet security? Is your data safe in your personal computer? If yes, think again.
There are skilled and secretive hackers who could get past pretty much anything you choose to put in their way.
Every aspect of our lives, important or not so important is saved on a computer which is connected with every other computer on the planet through a complex web of networks.
Not only are these hackers fiendishly clever, they are also inventive and constantly invent new ways of getting past security protocols.
You should be grateful than the most of the skilled hackers choose to concentrate on draining millions from banks rather than sending messages to your friends pretending to be you.
