Technology as drivers for fraud detection and investigation
Fraudsters are increasingly becoming “tech savvy” and are exploiting control
weaknesses in IT systems to perpetuate fraud.
Modern day Fraud is hidden in large data volumes, making it difficult to
detect by manual spot checks

IT tools and TechniquesData analytics;
1. Trend analysis- Comparison of same period numbers such as suppliers, customers,
employee, over time.
2. Ration Analysis- unusual transactions represent a deviation from the norm.
3. Duplicate transactions-- unique identifier values such as invoice numbers,
sequential,

IT tools and Techniques
4. Even Amounts- examine even amounts, rounded-off numbers
5. Outlier amounts- discovering data values that are outside the normal course of
business.
6. Benford’s Law- nature produces more small things than large things, businesses
produce more transactions with small amounts than with large amounts.

Using Data Analytics for Fraud Auditing
Data analytics in Fraud Audit
• Fraud test definition . Identify and define fraud indicators to test based on business rules,
experience and known fraud schemes.
• Data identification and extraction -Which IT system store data required. Extraction of
this data to be done in a controlled environment. Formal request of data prior to audit

Using Data Analytics for Fraud Auditing
• Data cleansing- Clean the data, convert to a format suitable for analysis. Import into analysis
software for test execution.
• Data analysis- fraud tests interpretation, suitable technical data tests and analysis by use of
data interrogation techniques to identify unusual trends, data anomalies and control lapses.
• Reporting and monitoring- Generate reports, business focused, easy to understand,
summarized results, data insights. Re-perform of these tests on a periodic basis
