Phishing Phishing is a form of social engineering attack that aims at encouraging internet users to reveal sensitive information such as bank login credentials and credit card numbers through websites that appear legitimate. Attackers, in this case, pretend to be companies or acquaintances that send messages containing links to phishing websites. Ollmann (2004) conducted a survey that revealed 57 million internet users received phishing emails in the United States and 2 million victims were compromised. Another survey revealed that there were 1,862 data breaches in 2021, with each breach costing businesses an average of $4.65 million (Fowler, 2022). This study discusses the types of phishing attacks, their implications, challenges and ways of identifying and preventing them. Phishing attacks in the airline, education and healthcare sectors in the United States led to losses of about US$100 million (Sadiq et al., 2021). Attackers used email phishing to steal workers’ login ...
