Nowadays, since the vast majority of the population actively uses the internet, internet users represent the most easily accessible and attractive target for fraudsters. The active use of the internet and technological development have created new types of risks in terms of fraud. 

One of the most common forms of internet fraud is phishing. The term "phishing" comes from the English word "fishing." Within this scheme, fraudsters obtain information about internet users for personal gain, such as: personal identification number, internet banking password, bank card or account number, patient's medical history, and other confidential data.

Typically, phishing is carried out by mass sending of emails, where the sender is indicated as a well-known organization or brand; also, through social networks. Fraudulent messages often contain a website link, the visual appearance of which is almost indistinguishable from the real page. However, when accessing the fake website, the information entered by the user—name and surname, password, bank card or account number, security code, etc.—automatically falls into the hands of the so-called "phisher." The website link sent to you may be real, but the service offered through this website may be fake. It is also common to receive fake offers via email, for example, requesting your data in exchange for receiving a cash prize, or asking for a symbolic amount to be transferred. Phishing can be carried out in several different ways.
