The article summarizes the results of research into phishing threats and attacks over a multi-year period. Obtained phishing emails are subject to statistical, frequency, and content analysis; messages are classified according to the content into five segments: Business, Fund, Charity, Transfer, and Others. An experiment of communicating with phishing attackers is described; necessary security measures are set for this. Protection against phishing attacks is solved by filtering incoming mail on the Microsoft Outlook client while applying rules with keywords obtained from individual segments. In a broader context, the cyber security of email communication is explained, and commercial tools for defense against phishing attacks are described. The usability of research results is also assumed in the education of university students and the training of employees of companies and organizations.
