G0071: Orangeworm
Orangeworm is a group that has targeted organizations in the healthcare sector in the United States, Europe, and Asia since at least 2015, likely for the purpose of corporate espionage.[1] Reverse engineering of Kwampirs, directly associated with Orangeworm activity, indicates significant functional and development overlaps with Shamoon.[2]

Executive priority
G0071: Orangeworm is an official MITRE ATT&CK group. 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 G0071: Orangeworm 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 G0071: Orangeworm 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.

How security teams should use this page
Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.
Techniques used
This mirrors the MITRE pattern of making group, software, campaign, and technique relationships scannable. Relationship notes come from mirrored ATT&CK relationship text when available.

Groups, software, and campaigns
S0236: Kwampirs
S0104: netstat
S0039: Net
The Net utility is a component of the Windows operating system. It is used in command-line operations for control of users, groups, services, and network connections. [1]
Net has a great deal of functionality, [2] much of which is useful for an adversary, such as gathering system and network information for Discovery, moving laterally through SMB/Windows Admin Shares using net use commands, and interacting with services. The net1.exe utility is executed for certain functionality when net.exe is run and can be used directly in commands such as net1 user.
S0100: ipconfig
S0106: cmd
cmd is the Windows command-line interpreter that can be used to interact with systems and execute other processes and utilities. [1]
Cmd.exe contains native functionality to perform many operations to interact with the system, including listing files in a directory (e.g., dir [2]), deleting files (e.g., del [3]), and copying files (e.g., copy [4]).
S0103: route
S0099: Arp
S0096: Systeminfo
Systeminfo is a Windows utility that can be used to gather detailed information about a computer. [1]

Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
