Active since ~2015 · Credential harvesting, Western political intelligence, Dossier building on targets
It builds a persona - a credible academic, a conference organizer, a think-tank researcher. It befriends. It follows for months.

The Callisto Group's reliance on persona-building and long-term relationship cultivation makes it slow. When exposed, the entire social infrastructure - the fake personas, the established trust - collapses simultaneously.
