Dissecting the JWR phishing framework

• Cisco Talos recently identified an undocumented phishing framework, internally branded "JWR" by its developer, built to convincingly impersonate checkout and login pages across major payment and shopping platforms.
• The client engine of the JWR phishing framework is a real-time, operator-driven system that, rather than merely logging form submissions like a static credential-stealing page, keeps an AES-CTR encrypted WebSocket open to the threat actor so they can steer each victim's session live.
• The victim data targeted by the actor using JWR extends well beyond payment data, encompassing identity documents, Social Security numbers, passport and driver's license images, website and PayPal credentials, 2FA codes, and full device fingerprints, all committed to the actor's server once a session ends.
• Talos assesses with medium confidence that the JWR phishing framework is a variant of "The Outsider," a phishing-as-a-service (PhaaS) platform, based on several similarities in the client engine scripts and functionalities of the two PhaaS platforms.
• Talos observed a real-world campaign delivering the JWR client via SMS lures impersonating toll authorities, and postal and courier services of several countries in Southeast Asia and the Middle East.

JWR phishing framework, a likely variant of the Outsider

JWR is a phishing framework capable of harvesting complete payment card data, login credentials, and personally identifiable information (PII) documents and images in real time.

The client-side engine of the framework impersonates login, and checkout flows of several payment gateways, including Shopify, PayPal, Apple, Klarna, and banks, while allowing the operator to stealthily control the victim session through an AES-CTR encrypted WebSocket channel.
