SecureBERT — CVE-LMTune ATT&CK Classifier (Flat)

Part of the CVE-LMTune model suite, a collection of language models fine-tuned for multi-taxonomy vulnerability classification across widely used cybersecurity taxonomies, including CWE, CAPEC, and MITRE ATT&CK.

Overview

This model performs multi-label ATT&CK classification from vulnerability descriptions. Given a CVE-style description, it predicts one or more ATT&CK identifiers associated with the described vulnerability.

Property	Value
Taxonomy	MITRE ATT&CK Enterprise Subtechniques
Task	Multi-label text classification
Input	Vulnerability description (e.g., CVE summary)
Output	One or more ATT&CK identifiers
Number of labels	175
Number of samples	231,009
Latest CVE update included	17/06/2026
Split	train (60%), val (20%), test (20%)

Evaluation Results

The model was evaluated on the held-out test set using standard multi-label classification metrics using sigmoid activation and a default threshold of 0.5.

Quick Start

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

tokenizer = AutoTokenizer.from_pretrained("Sana9/securebert-vuln2attack-flat")
model = AutoModelForSequenceClassification.from_pretrained("Sana9/securebert-vuln2attack-flat")

text = "Buffer overflow vulnerability in OpenSSL allows remote attackers to execute arbitrary code."

with torch.no_grad():
    probs = torch.sigmoid(
        model(**tokenizer(text, return_tensors="pt", truncation=True)).logits
    )[0]

predictions = {
    model.config.id2label[i]: p.item()
    for i, p in enumerate(probs)
    if p > 0.5
}

print(predictions)
