Spam is one of the most popular ways of spreading malware and infecting computers on the Internet. Attackers have various tricks to make victims install malicious software on their computers. Email traffic includes a variety of private emails, such as wedding invitations, dating offers and other similar messages. However, fake notifications from well-known companies and brands providing different services remain the most popular cybercriminal trick.
