Explain any four types of Cybercrimes.

Four types of Cyber crimes are:

1. Cyber stalking — It is a crime in which the attacker harasses a victim by using electronic communication, such as e-mail, instant messaging, or messages posted to a website or a discussion group for reason of anger, revenge, or control. A stalker may be an online stranger or a person whom the target knows.
2. Cyber bullying — It is an act of harming or harassing using information technology in a deliberate manner. This includes insulting remarks and threatening messages sent by e-mail, spreading rumours about the person either by e-mails or social networking sites, posting embarrassing photos and videos to hurt the person, derogatory remarks against gender, race, religion, or nationality.
3. Cyber espionage — It is the practice of using information technology to obtain secret information without permission from its owners or holders. Cyber espionage is most often used to gain strategic, economic, political, or military advantage, and is conducted using cracking techniques and malware.
4. Cyber Extortion — It is a crime that involves an attack coupled with a demand for money to stop further attacks. Cyber Extortion may involve a DoS (Denial of Service) attack or installation of Ransomware to access and block the system resources of the victim.
