Inteid — Pro-Russian Hacktivist Brand (DDoS-centric; Russian Legion member)

Classification: TLP: WHITE — Open Source Intelligence (OSINT)

Category: Cyber / Hacktivism (Disruption & Coercive Messaging)

Executive Summary

Inteid is assessed as a pro-Russian hacktivist brand primarily associated with denial-of-service disruption and public influence signaling. In late January–early February 2026, multiple independent sources describe Inteid as a member of the newly announced hacktivist alliance “Russian Legion,” alongside Cardinal, The White Pulse, and Russian Partizan, under the campaign name “OpDenmark.”

Truesec reporting states Inteid conducted a DDoS attack against Denmark’s health portal sundhed.dk “earlier this week” (relative to 2026-01-30), and a Danish sector outlet reports that the hacker group “inteid” claimed responsibility for a DDoS outage affecting sundhed.dk.

Truesec further observed that while Russian Legion messaging claims more advanced capability, the observed campaign to date has consisted only of DDoS attacks; it also noted “Phase 2” (“Operation Ragnarök”) and potential spillover targeting beyond Denmark.
