What type of fraud filter is MOST effective at preventing triangulation fraud within PayPal transactions?

The most effective type of fraud filter for preventing triangulation fraud within PayPal transactions is one that analyzes and flags inconsistencies between the shipping address, billing address, and IP address location. Triangulation fraud involves a fraudster using a stolen credit card to purchase goods from a legitimate online merchant, having those goods shipped to a different address (often a compromised account holder), and then selling those goods to an unsuspecting third party. By comparing these three address data points, a filter can identify suspicious patterns. For example, if the billing address is in one country, the shipping address is in another, and the IP address originates from yet another location, this raises a red flag and indicates a high probability of fraudulent activity. Implementing rules based on geographical disparities and address mismatches significantly reduces the risk of falling victim to triangulation fraud. The filter should be configurable to flag or automatically reject transactions that exhibit these inconsistencies, providing a robust defense against this specific type of fraudulent scheme.
