Emperador is a ransomware and data-extortion threat group active in 2026. The group has publicly claimed intrusions affecting organizations across the Americas, Europe, and Asia, including government bodies, healthcare providers, manufacturers, technology firms, educational institutions, professional-services organizations, transportation businesses, and energy-sector entities. Its victim claims commonly allege theft of corporate databases, personnel and customer records, financial information, operational documents, and credentials. Emperador uses ransom demands backed by threats to publish purportedly stolen data, including employee and salary information, if victims do not negotiate or pay. It has also claimed to contact victim organizations while impersonating security researchers. Available reporting does not independently verify the group’s asserted compromises, data volumes, or claims of ransomware encryption.
