Introduction
The rise of decentralized digital infrastructures and flexible adversary ecosystems has destabilized traditional cybersecurity assumptions. Threat actors today often operate not within rigid hierarchies but through fluid, self-organizing networks resembling rhizomes—a concept introduced by philosophers Gilles Deleuze and Félix Guattari (1987).[1] A rhizome, as described in A Thousand Plateaus, is a non-hierarchical, horizontally propagating structure with no defined center, characterized by multiplicity, constant regeneration, and no defined beginning or end. These "rhizomatic threats" lack fixed command centers, readily mutate identities, and form . . .
