Today, cybercrime in the general sense is a public and legislative issue, and it is becoming more widespread every day. Although all crimes endanger the security of the country and public welfare, this feature is more tangible in some of them. Cybercrime is directly related to the concepts of national security and public welfare. Many criminal acts that can be committed in physical and tangible space can also be carried out in cyberspace. In a general division, information crimes can be divided into two groups according to the philosophy of legislation. 1. A range of cybercrimes that can be prosecuted under classic criminal laws and do not require new legislation and can be categorized as crimes against persons, property, public safety and security, morality, public decency and family. 2. A range of computer crimes that were not possible at all before the advent of information technology, such as unauthorized access, unauthorized eavesdropping, data disruption, and system disruption. Given that, unfortunately, in recent years, along with the increase in the use of the Internet, we have witnessed an exponential increase in cybercrime, so criminal law should create new concepts and institutions, anticipate the necessary measures in line with technological advances, as well as complex opportunities for abuse. Consider the cyber environment facilities provided. In this regard, the present study aims to explain cybercrime from a conceptual and historical perspective.
