Book excerpt: Using recent research and case studies, this book offers an evidence-based insight into the embezzler’s mindset as they commit crimes that are costing nations, organisations and individuals increasingly more each year. This mindset is described in detail as the embezzler develops their motivation to steal from their employer, finds a method of stealing, assesses the risks, executes the theft, and then determines whether to continue to steal. The organisational landscape of security capabilities, culture and financial circumstances provide the environment that this mindset operates within. The embezzler’s approach to the crime is broken down into four stages: Pre-Existing Vulnerabilities, Induction to First Theft, Ongoing Theft and Detection to Resolution. The author recommends strategies based on the embezzler’s mindset for organisations to enhance their ability to protect themselves from such inside threats that attack their reputation, productivity, morale and, in the worst cases, financial viability.
