Executive priority
G0083: SilverTerrier 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 G0083: SilverTerrier 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 G0083: SilverTerrier 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.
| Domain | ID | Name | Relationship / procedure |
|---|---|---|---|
| Enterprise | T1071.003 | Mail ProtocolsSub-technique | SilverTerrier uses SMTP for C2 communications.[1] |
| Enterprise | T1071.001 | Web ProtocolsSub-technique | SilverTerrier uses HTTP for C2 communications.[1] |
| Enterprise | T1071.002 | File Transfer ProtocolsSub-technique | SilverTerrier uses FTP for C2 communications.[1] |
| Enterprise | T1657 | Financial Theft | SilverTerrier targets organizations in high technology, higher education, and manufacturing for business email compromise (BEC) campaigns with the goal of financial theft.[1][2] |
Groups, software, and campaigns
S0336: NanoCore
S0331: Agent Tesla
Agent Tesla is a spyware Trojan written for the .NET framework that has been observed since at least 2014.[1][2][3]
S0198: NETWIRE
S0334: DarkComet
S0447: Lokibot
Lokibot is a widely distributed information stealer that was first reported in 2015. It is designed to steal sensitive information such as usernames, passwords, cryptocurrency wallets, and other credentials. Lokibot can also create a backdoor into infected systems to allow an attacker to install additional payloads.[1][2][3]

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 |
|---|---|---|---|---|---|
| 19.2 | 1.2 | Current bundle | e12da22ca7f4… | ||
| 19.1 | 1.2 | Older bundle | f310a45a5a22… |
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.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
