Abstract-Organizations often suffer harm from individuals who bear no malice against them but whose actions unintentionally expose the organizations to risk-the unintentional insider threat (UIT). In this paper we examine UIT cases that derive from social engineering exploits. We report on our efforts to collect and analyze data from UIT social engineering incidents to identify possible behavioral and technical patterns and to inform future research and development of UIT mitigation strategies.

Organizations often suffer harm from individuals who bear them no malice but whose actions unintentionally expose the organizations to risk in some way. This paper examines initial findings from research on such cases, referred to as unintentional insider threat (UIT). The goal of this paper is to inform government and industry stakeholders about the problem and its possible causes and mitigation strategies. As an initial approach to addressing the problem, we developed an operational definition for UIT, reviewed research relevant to possible causes and contributing factors, and provided examples of UIT cases and their frequencies across several categories. We conclude the paper by discussing initial recommendations on mitigation strategies and countermeasures.
