Hacking has been around almost as long as the Internet; some people just love to try and break into a computer system.
Prior to 1990, there was no legislation in place to tackle the problems caused by hacking. Although everyone knew that it was wrong and should be against the law, there was nothing that anyone could do about it.
As the problem grew, it became apparent that specific legislation was needed to enable hackers to be prosecuted under the law.
So, in 1990, the Computer Misuse Act was passed.
The Computer Misuse Act (1990) recognised the following new offences:
Unauthorised access to computer material
Unauthorised access with intent to commit or facilitate a crime
Unauthorised modification of computer material.
Making, supplying or obtaining anything which can be used in computer misuse offences
