# Cyber Threat Intelligence Dataset

> A comprehensive cybersecurity dataset combining **CVE vulnerability data**, **MITRE ATT&CK techniques**, and **CISA Known Exploited Vulnerabilities** — structured for AI/ML training and security research.

**Author:** [Soham Dahivalkar](https://www.linkedin.com/in/soham-dahivalkar-82415426a)

**Created:** 2026

## Dataset Description

This dataset provides structured cybersecurity intelligence data collected from three authoritative public sources:

1. **NVD (National Vulnerability Database)** — CVE vulnerability records with CVSS scoring
2. **MITRE ATT&CK** — Enterprise attack techniques, tactics, and detection methods
3. **CISA KEV** — Known Exploited Vulnerabilities actively used in the wild

Each CVE record is enriched with:
- CVSS v3.1 base scores and detailed metrics
- Attack type classification (mapped from CWE)
- MITRE ATT&CK tactic mapping
- Custom risk scoring (0-100)
- CISA KEV status (actively exploited or not)
- Ransomware usage indicators

Additionally, the dataset includes **instruction-tuning data** for fine-tuning LLMs as cybersecurity analysts.

## Dataset Structure

### Configurations

| Split | Description | Rows |
|-------|-------------|------|
| `cve_data` | CVE vulnerability records with CVSS, CWE, risk scores | ~5000 |
| `mitre_attack` | MITRE ATT&CK enterprise techniques | ~700 |
| `train` | Instruction-tuning training split | ~15000 |
| `test` | Instruction-tuning evaluation split | ~1500 |

### CVE Data Schema

| Column | Type | Description |
|--------|------|-------------|

## Usage

### Load the Dataset

```python
from datasets import load_dataset

# Load all splits
dataset = load_dataset("soham-dahivalkar/cyber-threat-intelligence")

# Access CVE data
cve_data = dataset["cve_data"]
print(f"Total CVEs: {len(cve_data)}")
print(cve_data[0])

# Access MITRE techniques
mitre = dataset["mitre_attack"]
print(f"Total techniques: {len(mitre)}")

# Access training data
train = dataset["train"]
print(f"Training samples: {len(train)}")
print(train[0]["instruction"])
```

### Filter Critical Vulnerabilities

```python
critical_cves = cve_data.filter(lambda x: x["risk_level"] == "CRITICAL")
print(f"Critical CVEs: {len(critical_cves)}")
```

### Get Actively Exploited CVEs

```python
exploited = cve_data.filter(lambda x: x["in_cisa_kev"] == "True")
print(f"Actively exploited CVEs: {len(exploited)}")
```

### Use for Fine-Tuning

```python
# Ready-to-use instruction format
for sample in dataset["train"]:
    instruction = sample["instruction"]
    input_text = sample["input"]
    output = sample["output"]
    # Format for your model and train!
```

## Intended Uses

- **Fine-tuning LLMs** for cybersecurity analysis tasks
- **Training classifiers** for vulnerability severity prediction
- **Building RAG systems** for security knowledge retrieval
- **Research** on automated vulnerability assessment
- **Education** on cybersecurity threat intelligence

## Limitations

- CVE descriptions are sourced from NVD and may not reflect the latest updates
- Risk scores are computed using a custom formula and may differ from organizational assessments
- MITRE ATT&CK mappings from CWE are approximate and based on common associations
- The instruction-tuning data is synthetically generated from structured fields
