Pakistan Arrests 21 in ‘Heartsender’ Malware Service

Pakistani authorities arrested 21 people allegedly behind Heartsender (aka Fudpage/Fudtools), a decade‑long spam and malware distribution service that sold phishing kits and fully-undetectable (FUD) tooling to organized crime groups for BEC and fraud. The report notes FBI and Dutch police seizure of the service infrastructure in January 2025, a 2024 data leak exposing customer and employee records, claims of over $50M in U.S. losses, and identification of key operators tied to WeCodeSolutions and The Manipulaters.
