C0026: C0026
C0026 was a campaign identified in September 2022 that included the selective distribution of KOPILUWAK and QUIETCANARY malware to previous ANDROMEDA malware victims in Ukraine through re-registered ANDROMEDA C2 domains. Several tools and tactics used during C0026 were consistent with historic Turla operations.[1]

Executive priority
C0026: C0026 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 C0026: C0026 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 C0026: C0026 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
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.
S1074: ANDROMEDA
S1076: QUIETCANARY
QUIETCANARY is a backdoor tool written in .NET that has been used since at least 2022 to gather and exfiltrate data from victim networks.[1]

S1075: KOPILUWAK

Object version and sync metadata
The fields below describe the current mirrored snapshot. When Glexia retains multiple ATT&CK source imports, you can open the table to compare the same object across releases (hashes and MITRE timestamps). For MITRE’s own release notes and roadmap, see ATT&CK resources — Updates.
Imported snapshots across ATT&CK releases(2)
| Release | Bundle imported | Object version | Modified | Status | Raw hash |
|---|---|---|---|---|---|

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.
