As all things in the world, even IT has its own inperfections. Using internet for online shopping or booking tickets have been popular in recent years and provided advantage for hackers and internet thiefs.

The potential threats of IT are:

Computer Virus - A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also commonly used to refer to other types of malware, including but not limited to adware and spyware programs that do not have the reproductive ability. A true virus can spread from one computer to another when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer. Also some types of viruses record everything you typed with your keyboard(i.e, your bank password) and send it to the creator which might use it for criminal purposes or buy things with your money.

Phishing - In the field of computer security, phishing is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and credit card details by making fake website which look trustworthy(i.e bank website). Communications purporting to be from popular social web sites, auction sites, online payment processors or IT administrators are commonly used to lure the unsuspecting public. Phishing is typically carried out by e-mail or instant messaging, and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Phishing is an example of social engineering techniques used to fool users,and exploits the poor usability of current web security technologies.

Cyber-bullying - Cyber-bullying has been defined as "when the Internet, cell phones or other devices are used to send or post text or images intended to hurt or embarrass another person", or as "when an electronic device is used to attack or defame the character of a real person. Often embarrassing or false information about the victim is posted in an online forum where the victim and those who know the victim can see it publicly."
Cyber-bullying has became more common in society because more people feel safer on internet and are more courageous than in real life where they have to speak face-to-face.
