Using Disposable Domain Names to Detect Online Card Transaction Fraud

Online card transaction fraud is one of the major threats to the bottom line of E-commerce merchants. In this paper, we propose a novel method for online merchants to utilize disposable (“one-time use”) domain names to detect client IP spoofing by collecting client's DNS information during an E-commerce transaction, which in turn can help with transaction fraud detection. By inserting a dynamically generated unique hostname on the E-commerce transaction webpage, a client will issue an identifiable DNS query to the customized authoritative DNS server maintained by the online Merchant. In this way, the online Merchant is able to collect DNS configuration of the client and match it with the client's corresponding transaction in order to verify the consistency of the client's IP address. Any discrepancy can reveal proxy usage, which fraudsters commonly use to spoof their true origins. We have deployed our preliminary prototype system on a real online merchant and successfully collected clients DNS queries correlated with their web transactions; then we show some real instances of successful fraud detection using this method. We also address some concerns regarding the use of disposable domains.
