What are the main tools to find frauds in companies operations as wells as in finance rather than bookish procedures?

If I was an auditor I would1st look for instances of window dressing.

• Instances of shares being overvalued.
• Profit projections non realistic
• Assets grossly over or undervalued.
• personal drWINGS OF THE top management showing as buss epenses. Could be travel epenses or special fees which di d not help the co at all.
• revenue expenses of current account paid from long term loans.

yes agree  with your answers but this is high level management involved in fraud , if somebody like employee who seeking suppliers payments and he involved in fraud, then what is the procedure to adopt?
