From these class assignment, we have given
the opportunity to know more about ransomware which we are not so familiar with
because Malaysia isn’t quite affected by these kind of destruction. However,
these knowledge is quite important if we are employeed after we graduated
because it may cause big trouble to our company we serve in the future if we
are not aware of it. Nothing is scary if we are well prepared with the knowledge
of it and we can prevent it when we know what causes it to happen.
