DoppelCart Fraud Network Exposes Massive E-Commerce Security Gap
In September 2026, cybersecurity researchers discovered DoppelCart, the largest documented fake e-commerce network comprising over 119,000 fraudulent domains, primarily using the .SHOP TLD. The operation impersonates 44,182 legitimate brands by copying product catalogs and branding, then uses WebSocket connections to steal payment card data, CVV codes, and personal information in real-time during checkout. The network affects 2.72% of all .SHOP domains and significantly surpasses previous operations like BogusBazaar's 75,000 sites, with over 105,000 shops remaining active at discovery. This incident highlights the evolving sophistication of financial fraud networks and their ability to operate at unprecedented scale through automated domain generation and brand impersonation, representing a critical threat to consumer trust and e-commerce security.
