Cybercrime involves using computers or the internet to commit traditional crimes like theft. There are many types of cybercrimes, including hacking into systems, denial of service attacks, using internet chat rooms for illegal purposes, credit card fraud, phishing for personal details, software piracy, distributing pornography, and spreading viruses. Criminals enjoy the anonymity and media attention from cybercrimes. Some common precautions include regularly updating antivirus software, using strong and unique passwords, backing up files, avoiding suspicious attachments, and logging out of computers when unattended.
