The purpose of the present Fraud and Corruption Awareness Handbook is to present United Nations staff with insights about fraud and corruption in the Secretariat, how they can occur, how they can be detected, and the systems of internal controls that the Organization has in place to mitigate and address fraudulent acts. The Handbook includes examples of potential indicators of fraud that might suggest the presence of potential wrongdoing. Specific case studies of how fraud has manifested itself in the Secretariat are also featured in the Handbook.
