Threats Affecting United States

A sophisticated traffic distribution system has been operating for over 14 months, using more than 12,700 structurally similar fake CAPTCHA PDFs hosted on Webflow's CDN. The operation begins with search engine optimization, where victims searching for legitimate content encounter malicious PDFs through Google searches. These documents contain fake CAPTCHA panels that route users through a custom Elixir/Phoenix traffic distribution system employing IP filtering, bot detection, and geographic targeting. The infrastructure sorts visitors and redirects qualifying traffic to three distinct endpoints: Legion Loader distribution, a TDS reseller gate, and premium-SMS subscription scams targeting Spanish-speaking users. Non-qualifying traffic is monetized through search-arbitrage advertising. The operation primarily targets English-speaking countries and has recently been surfaced by AI assistants including Google Gemini and Claude, expanding its reach beyond traditional search engines.

The Greatness phishing-as-a-service (PhaaS) platform targets Microsoft 365 accounts using advanced phishing techniques including adversary-in-the-middle and device-code phishing. It spoofs RingCentral emails to bypass email security filters by exploiting whitelisting and safe-sender list trust. Post-compromise, attackers access Microsoft 365 data and services via stolen authentication tokens. The platform is sold to cybercriminals and has been active since at least mid-2022, targeting users in multiple countries. Researchers recommend auditing safe-sender lists and monitoring suspicious MFA-approved sign-ins.
