# MITRE ATT&CK T1087.002: Domain Account
## When to use this skill
Use this skill when the task involves T1087.002, Domain Account, enterprise ATT&CK, TTP mapping, detection engineering, hunting, incident-response enrichment, control validation, or authorized adversary-emulation planning. Treat it as a defensive analysis aid: keep outputs focused on understanding, detecting, mitigating, and safely validating this ATT&CK sub-technique.
## Technique context
- ATT&CK domain: enterprise
- ATT&CK ID: T1087.002
- Technique name: Domain Account
- Type: sub-technique
- ATT&CK URL: https://attack.mitre.org/techniques/T1087/002
- Tactics: discovery
- Platforms: Linux, macOS, Windows
- Required permissions: Not specified
- Effective permissions: Not specified
- Defenses bypassed: Not specified
## ATT&CK description
Adversaries may attempt to get a listing of domain accounts. This information can help adversaries determine which domain accounts exist to aid in follow-on behavior such as targeting specific accounts which possess particular privileges.
Commands such as net user /domain and net group /domain of the [Net](https://attack.mitre.org/software/S0039) utility, dscacheutil -q group on macOS, and ldapsearch on Linux can list domain users and groups. [PowerShell](https://attack.mitre.org/techniques/T1059/001) cmdlets including Get-ADUser and Get-ADGroupMember may enumerate members of Active Directory groups.(Citation: CrowdStrike StellarParticle January 2022)
## Agent workflow
1. Clarify scope: identify the system, asset class, log sources, cloud or endpoint platform, and whether the user wants triage, detection, coverage assessment, or safe emulation planning.
2. Load bundled resources as needed: use `references/technique-profile.json` for structured metadata, `references/detection-and-mitigation.md` for triage and telemetry guidance, `references/known-threat-context.md` for ATT&CK relationship context, and `templates/` for repeatable outputs.
3. Map observations to ATT&CK: compare the user's evidence to the ATT&CK description, tactics, platforms, and known procedure patterns before asserting a match.
4. Produce defensive outputs: prioritize hypotheses, telemetry requirements, detection logic ideas, validation steps, containment guidance, and mitigations.
5. Preserve uncertainty: distinguish confirmed evidence, plausible indicators, assumptions, and gaps. Recommend what to collect next.
6. Stay safe: do not provide malware, credential theft, persistence, evasion, destructive automation, or unauthorized exploitation instructions. For adversary emulation, keep steps bounded to approved lab or control-validation contexts and omit operational abuse details.
## Bundled resources
- `references/technique-profile.json`: machine-readable ATT&CK metadata for this technique.
- `references/detection-and-mitigation.md`: detection notes, telemetry checklist, triage questions, mitigation candidates, and false-positive considerations.
- `references/known-threat-context.md`: ATT&CK relationship context with attribution cautions.
- `templates/detection-brief.md`: detection engineering brief template.
- `templates/hunt-plan.md`: threat hunt plan template.
- `templates/incident-response-note.md`: incident response note template.
- `templates/coverage-assessment.md`: ATT&CK coverage assessment template.
- `scripts/render_brief.py`: local helper that renders a Markdown defensive brief from `technique-profile.json`.
- `assets/output-schema.json`: JSON schema for structured technique analysis outputs.
To generate a quick brief, run `python scripts/render_brief.py --output brief.md` from inside this skill directory, or adapt the templates directly.
## Detection guidance
No ATT&CK detection guidance was present in the source STIX object.
## Useful telemetry and data sources
- Not specified in the STIX object.
## Mitigations to consider
- Operating System Configuration
## Known threat context
Use these examples only as contextual leads, not as proof that an observed event is this technique:

- Bankshot (malware)
- Bazar (malware)
- BlackByte (intrusion-set)
- BlackCat (malware)

## Recommended output pattern
When responding with this skill, structure the answer as:
- Assessment: whether the evidence supports this ATT&CK mapping and why.
- Evidence: specific indicators, logs, behaviors, and assumptions.
- Detection: telemetry sources, analytic logic, and tuning considerations.
- Response: containment, eradication, recovery, and validation actions.
- Coverage gaps: missing logs, sensors, controls, or environmental details.
- References: include the ATT&CK URL and any user-provided evidence references.
