C0042: Outer Space
Outer Space was a campaign conducted by OilRig throughout 2021 that used the SampleCheck5000 downloader and Solar backdoor to target Israeli organizations.[1]
Security context for executives and security teams
C0042: Outer Space describes [Outer Space](https://attack.mitre.org/campaigns/C0042) was a campaign conducted by [OilRig](https://attack.mitre.org/groups/G0049) throughout 2021 that used the [SampleCheck5000](https://attack.mitre.org/software/S1168) downloader and [Solar](https://attack.mitre.org/software/S1166) backdoor to target Israeli organizations.(Citation: ESET OilRig Campaigns Sep 2023)
Executive priority
C0042: Outer Space is an official MITRE ATT&CK campaign. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.
Technical view
Security teams should validate C0042: Outer Space by reviewing the official ATT&CK relationships, mapped tactics (the mapped ATT&CK tactic context), supported platforms (the platforms named in the official object), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
Detection direction
- Validate whether C0042: Outer Space appears in your detection coverage and tabletop scenarios.
- Use the object to align executive risk language with SOC, incident response, and detection engineering work.
- Do not treat ATT&CK relationship context as attribution without corroborating evidence.
Mitigation priorities
- Map the object to existing controls and identify missing telemetry or response ownership.
- Prioritize mitigations that reduce exposure on the listed platforms and tactics.
- Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits
Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.
This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

Groups, software, and campaigns
G0049: OilRig
OilRig is a suspected Iranian threat group that has targeted Middle Eastern and international victims since at least 2014. The group has targeted a variety of sectors, including financial, government, energy, chemical, and telecommunications. It appears the group carries out supply chain attacks, leveraging the trust relationship between organizations to attack their primary targets. The group works on behalf of the Iranian government based on infrastructure details that contain references to Iran, use of Iranian infrastructure, and targeting that aligns with nation-state interests.[1][2][3][4][5][6][7]
S1166: Solar
Solar is a C#/.NET backdoor that was used by OilRig during the Outer Space campaign to download, execute, and exfiltrate files.[1]
S1168: SampleCheck5000
SampleCheck5000 is a downloader with multiple variants that was used by OilRig including during the Outer Space campaign to download and execute additional payloads. [1][2]
