Abstract

Most Web Security mechanisms depend on users’ ability to interpret visual signals. For example, the lock icon next to the website URL lets users know that the website they are visiting is secure. These mechanisms, however, are challenging for people with visual impairments. While screen readers help with website navigation, they rarely account for security vulnerabilities. To better understand this issue, we conducted a user study to analyze what screen reader users do when they encounter potential phishing scams (websites, emails), whether they can successfully detect phishing scams, and the challenges they face when they encounter such scams. The user study sessions consisted of two components: completion of tasks, and an exit interview. Our findings highlight the need for email service security cues to be more accessible. Our study calls attention to a screen reader design challenge due to which users are unaware of missing visual elements on webpages. In addition, we found that screen reader users do not check the address bar on webpages unless they find something suspicious in the webpage. This could be potentially exploited by scammers.
