Hacktivist

What is Hacktivist?

HacktivistA threat actor who carries out cyber attacks to advance a political, social, or ideological cause rather than for financial gain or state intelligence objectives.


Hacktivists publicise their grievances through defacements, leaks of sensitive documents ("hack and leak"), DDoS, doxxing, and disruption of services they consider unjust. Some are loosely organised online collectives such as Anonymous, LulzSec, GhostSec, or Anonymous Sudan; others align with geopolitical conflicts, such as IT Army of Ukraine, Killnet, NoName057(16), and Cyber Av3ngers. Capabilities range from basic DDoS-as-a-service to credential leaks of millions of records. Hacktivism frequently overlaps with nation-state operations either through deniable proxies or simply through state-aligned ideology, which complicates attribution and policy responses.
