The advanced computer technology of the modern age has given birth to many sophisticated hackers who are responsible for some of the deadliest cyber-attacks the world has ever seen in the recent history. The first was the widely publicized hacking of Sony Pictures in November 2014 in which a group named The Guardians of Peace hacked the database of the film studio and released several new films online. Then came the hacking of Hillary Clinton’s campaign during the 2016 US Election which led to the leak of thousands of confidential and private emails of the Democratic Party officials on WikiLeaks. Today, we are seeing another kind of cyber-attack, through a ransomware called WannaCry which has already affected more than 150 countries since last Friday.

What causes more panic for the victims is that the ransomware threatens to permanently delete all the files within a week if the ransom money is not paid.
