- Access a computer without permission.
- Access a computer without permission, hoping to break another law.
- Change, break or copy files without permission.
Most people who break this law can be fined for up to £2000 and jailed for up to 6 months if you live in Scotland and 12 months in the UK. However, people who do computer fraud, blackmailing through computers, or making computer viruses will get a fine of any amount and be jailed for up to 5 years.
It is very difficult to prove that people have committed any of these offences without proper knowledge and use of I.P addresses so the law has not worked very well. There have been very few successful prosecutions.
