Cybercrime involves the illegal use of computers and the internet. Common cybercrimes include hacking, illegal downloading, and cyberbullying. Vulnerable computers that lack security are easily accessed and exploited by criminals. The Cybercrime Act of 2001 in Australia established legal definitions and penalties for cybercrimes to help prevent such offenses and protect privacy online. While raising awareness of cybercrime risks, the laws must also be fair to young people.
