Broadly speaking, Cyber Crime is a wide range of ‘malicious activities’ including the illegal interception of data, system interference that compromise network integrity, availability and copyright infringements, So if we go to the   nature of this crime, it can be said that it is that type of crime in which computers and computer networks are put into use.
The definition of Cyber crime has not been defined anywhere in our Indian legal system. However it has enacted the Information Technology Act, 2000 with keeping following objectives in mind.
•  To Grant legal recognition of E- transactions, EDI, EFT and digital signature.
•  To Facilitate Electronic Filling of data, information and storage data.
•  To amend Indian Penal Code, Indian Evidence Act, Banker’s Book Evidence Act and Reserve Bank of India Act. (Source: - ITA)
According to statistics released by the National Crime Record Bureau (NCRB), Cybercrimes in India almost doubled in 2017. As per the report, “During 2017, 56% of cyber-crime cases registered were for the motive of fraud (12,213 out of 21,796 cases) followed by sexual exploitation with 6.7% (1,460 cases) and causing disrepute with 4.6% (1,002 cases).” The total number of offenses under the IT Act was the highest in Uttar Pradesh, followed by Karnataka (3,152), Rajasthan (950), Assam (941) and Maharashtra (586). However, the total number of offenses under the IT Act across the country stood at 13,635. The twentieth century has brought to reality the idea of a global village, where digital technology has interconnected and enmeshed the world economies, cultures and populations but at a same time we cannot avoid its dangerous effect... According to a 2017 report, Indian consumers had lost over 18 billion U.S. dollars due to cyber crimes. In 2018, there were over 27 thousand cases of cyber crimes recorded in the country, marking an increase of over 121 percent compared to the number of cases just two years back. While the nature of crimes ranges from petty online frauds to lottery scams and sexual harassment, the most targeted crimes seem to be in the banking and finance sector. (Source: -ncrb.gov.in)
Cyber crime may not happened only against individual rather it may be against companies/organization, society at large or against government etc, hence below are some crime related with different person:-
Cyber crime against individuals: - This is the one that directly affects any person or their properties. These are the few examples of this- cyber stalking, dissemination of obscene material, defamation, hacking, assault by threat, carding Etc.

It should also be noted here that section 66A of the said Act deals with the Punishment for sending offensive messages through communication service, etc. The Hon’ble Supreme Court in 2015 under the case of Shreya Singhal v. Union of India struck down section 66A of  ITA in its entirety as it violated the right to freedom of expression guaranteed under Article 19(1)(a) of the Constitution of India as an exception to the right, Article 19(2) permits the government to impose “reasonable restrictions in the interests of the sovereignty and integrity of India. (Source: -indiankanoon.org)
Conclusion:- Law is not static rather keeps on changing as per needs and circumstances of society change because we all know a new technology also creates new opportunities to commit crime. Hence IT act cannot be isolated from this effect, with keeping above view in mind, IT act also needs to be amended on time to time which should meet up and follow prevailing situation of society..!!
