For this reason, IP records, log records, bank transactions, device reviews and digital correspondence are among the most important elements of the process.
Cybercrime refers to crimes committed using an information system, internet, digital device, social media platform or electronic data. These crimes may be directly directed at the information system, or they may be committed by using the information system as a tool.

If sufficient suspicion arises, an indictment is prepared and a criminal case is opened. The court decides by evaluating the reliability, legality and connection of the digital evidence with the defendant.
