Predictive analytics in fraud detection has revolutionized the way financial institutions preemptively address and mitigate cyber threats, reducing the incidence of breaches and saving millions in potential losses.

Not only are online frauds getting more sophisticated, but they’re also continuously increasing in number and show no signs of slowing down. For example, a report that was published by Recorded Future shows that about 60 million payment card records were compromised in the year 2022 and were posted on the dark web for sale. 

Traditional fraud detection methods, such as manual audits and investigations, have limitations in speed, accuracy, and scalability. That is where the use of predictive analytics comes into place because it provides a new avenue for detecting and preventing fraud.

Predictive modeling is a mathematical process used to predict future events or outcomes by analyzing patterns in a given set of input data. It is a crucial component of predictive fraud analytics, a type of data analytics that uses current and historical data to forecast activity, behavior, and trends.

Predictive analytics refers to the use of historical and current data to make predictions by employing statistical modeling, data mining, and machine learning algorithms. It helps you identify patterns in large datasets, uncover hidden risks of fraud, and take proactive action to prevent them.

Examples include estimating the likelihood of fraud or scams using the mobile application or peer-to-peer technology platform. These capabilities are often baked into various business applications, so it is worth understanding the mechanics of predictive modeling to troubleshoot and improve performance.

Although predictive modeling implies a focus on forecasting the future, it can also predict outcomes for example the probability a transaction is fraudulent. In this case, the fraud event has already happened. The goal here is to predict whether future analysis will find the transaction is fraudulent. Predictive modeling can also forecast future requirements or facilitate the what-if analysis.

Below are some of the challenges that institutions face in the process of implementing models based on predictive frauds analytics:

  • Fraudsters are constantly evolving and finding new ways to get around the systems to commit fraudulent activities. This makes it difficult for predictive analytics to keep up with the developed patterns and detect fraud. Therefore, machine learning models need to be continually updated to remain efficient and effective. Failure to update the models can result in a decrease in performance, rendering them useless.
  • Fraudsters and hackers use tools, such as The Onion Router or TOR, and virtual private network (VPN) services for mobile applications, computers, or other devices they use, to change their internet protocol addresses and locations. The use of bots further complicates the prediction process. These techniques make it hard for systems to detect the true location of malicious actors.
  • Despite the use of good Security Information and Event Management systems, high rates of false positive alerts still need to be solved. Analysts need to spend a lot of time accumulating and correlating true events from the large data pool. It is essential to eliminate such events before quantifying the data towards machine learning, which increases workload and distracts security teams from real security threats.

Final Thoughts

In an era where online fraud continuously morphs and escalates, traditional methods of fraud detection are rapidly becoming obsolete. The revelation by Recorded Future that approximately 60 million payment card details were compromised in 2022 underscores this alarming trend. However, the rise of predictive analytics, driven by mathematical models that decipher patterns from vast data sets, offers a glimmer of hope. By employing statistical modeling, data mining, and machine learning, this approach aims to proactively identify and counteract fraud risks.

For instance, its integration into mobile apps or peer-to-peer platforms can help forecast fraudulent activities. Yet, the relentless evolution of fraudsters, who leverage tools like TOR and VPNs, and the challenge of false positive alerts mean that while predictive analytics is a significant advancement, it isn’t a silver bullet. Keeping these systems updated, refined, and responsive is imperative to ensure their sustained efficacy against a relentless enemy.
