APT29 / Cozy Bear: threat actor report

APT29, attributed to Russia's Foreign Intelligence Service (SVR): its operations from SolarWinds to the earthquake-themed campaign against Türkiye, its techniques against cloud identity infrastructure, and IoCs per campaign.

IG-TA-APT29 28.10.2024 95 pages Report language: Turkish

Key findings

  • 01Through SUNBURST, planted in a SolarWinds Orion update, APT29 reached thousands of organisations from a single supply-chain step.
  • 02Golden SAML and the hijacking of Azure AD applications show the group gaining persistence in cloud identity infrastructure without needing passwords.
  • 03The phishing campaign that used the earthquake in Türkiye as a lure shows how quickly current events are turned into decoy documents.
  • 04Legitimate admin tools such as AADInternals, AdFind and BloodHound are preferred over malware during reconnaissance.

Active since at least 2008, APT29 (Midnight Blizzard, NOBELIUM, The Dukes) targets government networks, diplomatic missions, research institutes and think tanks. The group is known for patient, long-term access and for its ability to reach thousands of organisations through a single software update, as in the SolarWinds Orion supply-chain attack.

The report examines identity-focused techniques such as DLL side-loading, Golden SAML and the hijacking of Azure AD applications. The campaign that used the earthquake in Türkiye as a lure is covered as a separate case study; hashes for PinchDuke, CosmicDuke, Operation Ghost and other campaigns are appended.
