Cybercrime is defined as “illicit activity carried out using the computer system and the Internet” punishable by law. With the increasing penetration of the Internet, cybercrimes have also increased in recent years. Between 2011 and 2015, the number of cybercrimes recorded in the country increased fivefold. In Maharashtra and Uttar Pradesh alone, 1/3 of these crimes occurred. Cybercrime in India is registered under three criteria, the IT Act, the Indian Penal Code (IPC) and other state level legislations (SLL). With the increasing penetration of mobile telephony and internet in the country, cyber crimes have also increased commensurately. Between 2011 and 2015, more than 32,000 cyber crimes were reported across the country. More than 24,000 cases have been registered under the IT Act and the remaining under various sections of the IPC and other state-level legislations. Any criminal activity that uses a computer as a tool, target or means to perpetuate crimes falls under the category of cyber crimes. The first cybercrime was recorded in 1820 in France. Cybercrime has been a problem since the late 1970s. The first spam email dates back to 1978, and the first virus was installed on Apple computer in 1982. Around 2000 complaints related to cybercrime were received in 2006, and the main reasons for those complaints were financial fraud, viruses, and hackers. There has also been a steady increase in the number of children exposed to unwanted pornography, Internet harassment and bullying. Computer crime, also called computer crime, is the use of a computer as a tool for ulterior illegal purposes, such as committing fraud, child pornography, identity theft, invasion of privacy. Cybercrime, especially through the Internet, has grown in importance as the computer has become central to commerce, entertainment, and government. Cybercrime mainly consists of unauthorized access to computer systems, alteration of data, destruction of data, theft of intellectual property. Most cybercrime involves an attack on the information of individuals, companies, or governments. Although the attacks do not take place against a physical body, they do take place on the personal or corporate virtual body, which is the set of information attributes that define people and institutions on the Internet. Cybercrime also includes non-pecuniary crimes such as creating and distributing viruses on other computers or publishing confidential company information on the Internet. Types of Cyber ​​Crime When a crime is committed on the Internet it is called a cyber crime. There are many types of cyber crimes and the most common ones are: Hacking: This is a type of cyber crime where a person's computer is hacked so that their personal or sensitive information can be accessed. In India, hacking is classified as a crimeand it is punishable. This is different from ethical hacking, which many organizations use to test their Internet security protection. In hacking, the criminal uses a variety of software to access a person's computer, and the person may not realize that their computer is being accessed from a remote location. Theft This crime occurs when a person violates copyrights and downloads music, videos, films and games. There are also peer-sharing websites that encourage software piracy, and many of these websites are now being targeted by the government. Cyber ​​Stalking This is a kind of online harassment where the victim is subjected to a barrage of online messages and emails. Typically, these stalkers know their victims and instead of resorting to offline stalking, they use the Internet to stalk them. Identity Theft This has become a major problem for people who use the Internet for cash transactions and banking services. In this cybercrime, the criminal accesses a person's bank account, credit card, Social Security, debit card, and other sensitive information to obtain money or purchase items online in the victim's name. It can lead to serious financial losses for the victim and even ruin the victim's credit history. Malicious softwareThis is Internet-based software or programs used to disrupt a network. The software is used to access a computer system to steal sensitive information or data or cause damage to the software on the system. Child Solicitation and Abuse This is also a type of cybercrime where criminals solicit minors via chat rooms for the purpose of child pornography. The government has spent a lot of time monitoring chat rooms frequented by children with the hope of reducing and preventing child abuse and grooming. Spam and PhishingSpamming and phishing are two very common forms of computer crimes. There's not much you can do to control them. Spam is basically unwanted emails and messages. Phishing is a method in which cybercriminals offer a bait so that you can capture them and provide the information they want. The bait can take the form of a commercial proposal, the announcement of a lottery you have never signed up for and anything that promises you money for nothing or a small favor. Social engineering is a method by which cybercriminals contact you directly using emails or telephones, especially the latter. They try to gain your trust, and once they succeed, they get the information they need. This information can be about you, your money, your company where you work, or anything that could be of interest to cyber criminals.
