Its main objective, set out in the preamble, is to establish a common criminal policy to protect society from cybercrime, including by adopting appropriate legislation and encouraging international cooperation. Since its entry into force, major countries, such as Brazil and India, have refused to accept the agreement on the grounds that they had not been involved in its development. Russia opposes the convention and states that acceptance would violate Russian sovereignty and has generally refused to cooperate with criminal investigations into cybercrime. It is the first legally binding multilateral instrument to regulate cybercrime.  Since 2018, following an increase in cybercrime, India has resumed its position on the Convention, although concerns remain about the exchange of data with foreign authorities.  Since 2001, the only global agreement to curb certain types of online abuses has been the Budapest Convention, drawn up by the Council of Europe with the support of some world powers, including the United States. Prior to the vote, concerns had been expressed, with U.S. Deputy Ambassador Cherith Norman Chalet of the Assembly saying that the resolution “would undermine international cooperation on cybercrime at a time when enhanced coordination is needed.” Some UN members may have been “bought out” by supporters of a controversial UN resolution on cybercrime in exchange for support for the plans, a Council of Europe cybersecurity official told EURACTIV. The Convention on Cybercrime, also known as the Budapest Convention on Cybercrime or the Budapest Convention, is the first international treaty to combat cybercrime, harmonizing national laws, improving investigative techniques and strengthening cooperation between nations.   It was developed by the Council of Europe in Strasbourg, France, with the active participation of the observer states of the Council of Europe, Canada, Japan, the Philippines, South Africa and the United States. Last month, Russia adopted a resolution on cybercrime, which could face challenges for countries that support a free and open internet model.
The convention contains a list of offences that each signatory state must transpose into its own right.
