Base de datos de 1.700 millones de registros de una telco india a la ventaA BreachForums user posted on 15 November 2026 an offer for an Indian telecom database said to contain 1.7 billion records. If authentic, it would be one of the largest subscriber-data leaks to date, enabling SIM-swap, account takeover and large-scale fraud. The figure closely matches recycled Indian telecom and identity data that has circulated for years, so authenticity must be verified before treating it as new.LeakPriority 82
