Abstract: Phishing is a cybercrime that is increasing exponentially day by day. In phishing, a phisher employs social engineering and technology to misdirect victims towards revealing their personal information, which can then be exploited. Despite ongoing research to find effective anti-phishing solutions, phishing remains a serious security problem for Internet users. In this paper, an investigation of using CAPTCHA keystroke dynamics to enhance the prevention of phishing attacks was presented. A controlled laboratory experiment was conducted, with the results indicating the proposed approach as highly effective in protecting online services from phishing attacks. The results showed a 0% false-positive rate and 17.8% false-negative rate. Overall, the proposed solution provided a practical and effective way of preventing phishing attacks.
