Practice shows that if a carder in Canada works through a VPN, proxy and other services, and also complies with the rules of Internet security, it is almost impossible to prove his guilt. But everyone is wrong… However, even if the police descend on carder’s home, the officers will still have to prove the fact of committing a computer crime . And if there are no traces, then there is no trial. They are most often caught on correspondence in messengers, the presence of data from other people’s cards and accounts, assemblies of malicious software, etc. But if you use portable software, anonymization tools, self-destructing messages and crypto-protected messengers, it will be difficult to prove something.
