SRC-UNIT42-OILRIG-DNS-TUNNELING
Behavior
| Actor | Behavior Summary |
|---|---|
| OilRig | OilRig/APT34 DNS tunneling family that encodes command-and-control over DNS queries. |
Hash And IOC Status
| Actor | Status | Reference |
|---|---|---|
| OilRig | Hash not committed; use Unit 42 IOC references if needed. | SRC-UNIT42-OILRIG-DNS-TUNNELING |
Hashes and IOCs on this page are source pointers or representative public indicators. They SHOULD be refreshed from the linked source before operational use and MUST NOT be used alone for actor attribution.
Defensive Hunting Notes
| Actor | Hunting Notes |
|---|---|
| OilRig | Hunt high-entropy subdomains, long query names, and high-frequency single-domain DNS from one host. |
Handling Notes
| Actor | Handling Notes |
|---|---|
| OilRig | DNS patterns require local baseline tuning. |

Related Actor-Level Repository Detections
These detections are mapped through the associated actor or scenario and are not automatically tool-specific. Promote a tool-specific detection only after the behavior is tied to telemetry and test evidence.
No repository detection is currently mapped to the associated actor(s). Use the hunting notes and source references as backlog input.
Related Actor-Level Hunts
These hunts are mapped through the associated actor or scenario and may need narrowing before they are used for this specific tool.
No repository hunt is currently mapped to the associated actor(s). Create a hunt from the behavior and telemetry notes before proposing a production detection.
