Iranian MOIS group conducting espionage across the Middle East since 2014 using DNS tunneling, custom tools, and social engineering. This profile is mapped to MITRE ATT&CK G0049 and covers attribution, tooling, targeting, and defensive recommendations based on observed campaigns.
Overview & Attribution
OilRig (also tracked as APT34, Helix Kitten, Hazel Sandstorm, EUROPIUM) is a threat group attributed to Iran. The group primarily targets Government, energy, telecoms, financial, Middle East for intelligence collection and operational objectives aligned with state interests.
This group is tracked as G0049 in the MITRE ATT&CK framework. All techniques referenced in this report are mapped to ATT&CK for consistent threat modeling and detection engineering.
Arsenal & Tools
Known tools and malware associated with OilRig include:
- RDAT
- BONDUPDATER
- Karkoff
- Shark
- SideTwist
Targeting & Operations
OilRig operations focus on Government, energy, telecoms, financial, Middle East. The group typically gains initial access through spear-phishing, exploitation of public-facing applications, or strategic web compromises before deploying custom implants for persistent access and data exfiltration.
Organizations in the Government sector should treat OilRig as a relevant threat and validate their detection coverage against the MITRE ATT&CK techniques listed below.

Notable Campaigns
This threat group has been active in operations targeting Government, energy, telecoms, financial, Middle East. Security researchers have documented campaigns involving RDAT and other tools deployed against organizations in multiple countries. Attribution confidence varies by campaign, but consistent infrastructure and TTP overlap links activity to Iran-nexus operations.
Detection & Defense
Recommended defensive measures against OilRig:
- Network monitoring: Detect C2 beaconing patterns associated with RDAT and related implants
- Endpoint detection: Deploy behavioral rules for the ATT&CK techniques above, particularly T1566.001 and T1059.001
- Email security: Implement robust phishing defenses including URL sandboxing and attachment detonation
- Patch management: Prioritize patching of internet-facing applications exploited by this group
- Threat hunting: Proactively hunt for IOCs and behavioral indicators mapped to G0049 in MITRE ATT&CK
