E-Commerce Security and Fraud Signals
highWhat is E-Commerce Fraud?
E-commerce applications face unique attack vectors including payment form skimming, coupon/promo abuse, account takeover for stored payment methods, and business logic flaws in checkout flows that enable price manipulation.
How it works
Attackers inject card-skimming scripts (Magecart) into payment pages, exploit business logic flaws to manipulate prices or bypass payment, use stolen credentials for account takeover to access stored payment methods, and abuse referral/coupon systems through automated enumeration.
Impact
Credit card theft affecting customers, financial loss from price manipulation, regulatory penalties (PCI DSS violations), customer trust damage, and chargeback costs.
ShieldReport scans for Magecart indicators, payment form security (CSP, SRI), price manipulation vectors in checkout APIs, and exposed admin/management endpoints that control pricing and inventory.
How to fix it
Implement Subresource Integrity for all payment page scripts. Deploy Content-Security-Policy to restrict script sources on checkout pages. Validate all pricing server-side. Use rate limiting on coupon endpoints. Implement fraud detection on payment flows.
