The term “cyber crime” coined by Barry Collins in 1980’s.[1] Bangladesh though slowly but is getting used to with internet technology in all spheres of life. Here social networking is also very popular among people especially young people to be connected with friends both real life friends and virtual life friends. In Bangladesh craze for Facebook is widely seen. More and more people are getting connected with it and threat of cyber crime on social network is increasing. To combat cyber crime Bangladesh has enacted Information Communication & Technology Act, 2006. Though it covered lots of offences but still it has some lacunas since new crimes or modes are increasing rapidly.

What is Cyber Crime?

Cyber crime is a technological crime. It is also known as computer crime, electronic crime, hi-tech crime and e-crime. Actually it involves a broad range of potentially illegal activities conducted by the misuse of computers and different types of communication networks. Dr. Debarati Halder and Dr. K. Jaishankar (cited in Alam p.213) define Cyber crimes as: "Offences that are committed against individuals or groups of individuals with a criminal motive to intentionally harm the reputation of the victim or cause physical or mental harm to the victim directly or indirectly, using modern telecommunication networks such as Internet (Chat rooms, emails, notice boards and groups) and mobile phones (SMS/MMS)".[2] The Oxford English Dictionary (cited in Alam p. 213) defines cybercrime as crime or a crime committed using computer or internet. Although the term cyber is technically limited to crimes involving the internet, it is used more broadly to refer the crimes committed using stand-alone computers.[3]

There are four types of cyber crimes:

1. Computer as the target of a crime

2. Computer as a tool of the crime

3. Computer as incidental to crime

4. Crime associated with the prevalence of computers.
