The document summarizes the Computer Misuse Act of 1990 in the UK, which established three computer-related offenses in response to increasing computer hacking. The offenses covered by the Act are: 1) unauthorized access to computer material; 2) unauthorized access with intent to commit further crimes; and 3) impairing a computer's operation through unauthorized access. The Act was broadened from its original focus on hackers. Prosecution under the Act has been rare and punishments light due to challenges proving offenses and collecting evidence. Cybercrime costs an estimated £27 billion annually in the UK.
