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.

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.

Usage

Load the Dataset

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

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

Get Actively Exploited CVEs

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

Use for Fine-Tuning

# 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
