  The mobile device is one of the fasted growing technologies that is widely
used in a diversifying sector. Mobile devices are used for everyday life, such
as personal information exchange - chatting, email, shopping, and mobile
banking, contributing to information security threats. Users' behavior can
influence information security threats. More research is needed to understand
users' threat avoidance behavior and motivation. Using Technology threat
avoidance theory (TTAT), this study assessed factors that influenced mobile
device users' threat avoidance motivations and behaviors as it relates to
phishing attacks. From the data collected from 137 mobile device users using a
questionnaire, the findings indicate that (1) mobile device users' perceived
susceptibility and severity of phishing attacks have a significant correlation
with a users' perception of the threat; (2) mobile device users' motivation to
avoid a threat is correlated to a users' behavior in avoiding threat; and (3) a
mobile device user's susceptibility to phishing attacks can be reduced by their
perception of the threat. These findings reveal that a user's perception of
threat increases if they perceive that the consequence of such threat to their
mobile devices will be severe, thereby increasing a user's motivation and
behavior to avoid phishing attack threats. This study is beneficial to mobile
device users in personal and organizational settings.
