Investigation of major financial scandals and ACFE reports in 2012-2022

The history of cheating goes back many years and it is a problem that still exists today. It cannot be completely prevented, but it can be brought under control with internal controls and ongoing audits. In addition, audits can help provide information on whether there are any problems with the business. A specific control environment is necessary for internal control to work effectively. Guidelines have been published by COSO (2012) to evaluate the effectiveness of internal control systems. The aim of this study is to explain why fraud, which has been in life since the existence of human beings, originates, types, theories and measures that businesses can take against cheating. Avoiding fraud is of paramount importance for any business. As a result of some scandals in the past, businesses attach great importance to fraud. Thanks to the reports published by ACFE, it is easily seen what kind of changes have occurred over the years. As a contribution to the literature of the study, it is thought to guide business managers, employees, customers and everyone who is exposed to fraud.
