Revived or reconstructed in the modern era

This page groups secret societies by how active and known they are today. Wikipedia notes that "Internet-based secret societies first became known to the public in 2012 when Cicada 3301 began recruiting from the public via Internet-based puzzles," and that "the goals of the society remain unknown." Browsing by status today lets a visitor separate a society that is publicly documented from one whose current activity remains genuinely uncertain.
