# MITRE ATT&CK T1683.001: Written Content

## When to use this skill

Use this skill when the task involves T1683.001, Written Content, 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 name: Written Content
- Type: sub-technique
- ATT&CK URL: https://attack.mitre.org/techniques/T1683/001
- Tactics: resource-development
- Platforms: PRE
- Required permissions: Not specified
- Effective permissions: Not specified
- Defenses bypassed: Not specified

## ATT&CK description

Adversaries may create or tailor written materials to support targeting and malicious operations. Content may include phishing lures, fraudulent financial communications, fabricated job postings, fabricated employment credentials and documentation, decoy documents, social media persona content, and supporting narratives used to sustain fabricated personas over time.(Citation: GenAI Phishing)(Citation: GTIG AI Threat Tracker) Content may be authored manually, commissioned through third parties, or produced using AI-assisted tools.

Written materials may impersonate legitimate government correspondence, diplomatic communications, or internal organizational documents to support targeting efforts. AI-assisted tools may also be used to tailor content to specific targets, industries, or regions. For example, adversaries may leverage AI to translate content into a target's native language or mimic the communication style of trusted senders.

Written content produced through these methods may be used in support of other techniques, such as [Phishing](https://attack.mitre.org/techniques/T1660), [Spearphishing via Service](https://attack.mitre.org/techniques/T1566/003), [Phishing for Information](https://attack.mitre.org/techniques/T1598), [Internal Spearphishing](https://attack.mitre.org/techniques/T1534), [Social Engineering](https://attack.mitre.org/techniques/T1684), [Financial Theft](https://attack.mitre.org/techniques/T1657), or [Establish Accounts](https://attack.mitre.org/techniques/T1585).

Written content does not include malicious code or scripts; for development of malicious code and scripts, see [Develop Capabilities](https://attack.mitre.org/techniques/T1587).

## 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

- Pre-compromise

## Known threat context

Use these examples only as contextual leads, not as proof that an observed event is this technique:

- APT-C-36 (intrusion-set)
- Contagious Interview (intrusion-set)

## 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.
