An Assessment of End-user Vulnerability to Phishing Attacks

ABSTRACT

Phishing has grown to become a significant threat to unsuspecting Internet users. This paper investigates user susceptibility to such attacks by assessing the degree to which they can differentiate between phishing messages and those that are genuine. A web-based survey was used to present a mix of 20 legitimate and illegitimate emails, and participants were asked to classify them and explain the rationale for their decisions. A total of 179 participants were involved in the study, and results reveal that they were 36% successful in identifying legitimate emails and 45% successful in spotting illegitimate ones.  Additionally, in many cases, the participants who identified illegitimate emails correctly could not provide convincing reasons for their selections.
