Root Cause

• Signs of unauthorized account access: Unusual login attempts, changes to account information, or abnormal transaction behavior indicate potential account compromise.

• Compromised payment credentials: Stored payment methods may have been accessed or used without authorization.

• High-risk transaction behavior: Multiple failed payment attempts, transactions from suspicious IP addresses, or sudden high-value purchases trigger fraud detection systems.

• Known fraud patterns detected: The activity matches known patterns of fraudulent behavior identified by the payment gateway or fraud prevention systems.

Troubleshooting and Solutions

• Immediately lock or suspend the customer's account to prevent further unauthorized activity.

• Contact the customer directly to verify their identity and confirm recent account activity.

• Suggest the customer to review and remove any unfamiliar or unauthorized payment methods linked to their account.

• Turn on 3D Secure authentication to authenticate the customers and reduce fraud attempts.

• Consult your fraud prevention team or payment gateway provider to analyze the activity further and update fraud detection rules if needed.
