# McNdroid: A Longitudinal Multimodal Benchmark for Robust Drift Detection in Android Malware


## Dataset Description

McNdroid is a large-scale, longitudinal, multimodal Android malware detection dataset designed to benchmark concept drift robustness. It spans samples collected from 2013 to 2025 and provides three complementary modalities: static feature vectors, API call graphs (GML), and JSON-based behavioral representations. The dataset also includes a rich metadata CSV and per-vendor family-level verdicts, supporting fine-grained label analysis and multi-label learning.

### Dataset Summary

- **Modalities:** Static features (NPZ), API call graphs (GML), JSON behavioral features
- **Time span:** 2013–2025
- **Total size:** ~10.9 GB
- **Splits:** Train/test per year with temporal evaluation protocols
- **Labels:** Binary (malware/benign) and multi-vendor family-level verdicts


### Supported Tasks

- Android malware detection (binary classification)
- Concept drift detection and temporal robustness evaluation
- Multi-modal learning for malware analysis
- Graph-based malware classification

### Data Fields

#### metadata.csv

Contains per-sample metadata including SHA256 hashes, collection timestamps, labels, and source information.

#### vendor_family_wide_verdict.csv

Contains malware family labels from multiple antivirus vendors, enabling multi-label and label-noise research.

#### Static Features (data_feature/)

Each year folder contains:
- `train_X.npz` / `test_X.npz`: Sparse feature matrices in NumPy compressed format
- `train_meta.npz` / `test_meta.npz`: Associated labels and sample metadata
- `vocab.json`: Feature name vocabulary mapping
- `selector_meta.json`: Feature selection metadata
- `split_meta.json`: Train/test split statistics

#### Graph Features (gml_feature/)

API call graphs stored in GML format, organized by year. Each graph represents inter-procedural API call relationships extracted via static analysis.

#### JSON Features (json_feature/)

Behavioral feature representations stored as JSON files, organized by year.


## Dataset Creation

### Source Data

Samples were collected from public malware repositories and benign application stores spanning 2013–2025. Each sample was processed through a static analysis pipeline to extract permissions, API calls, intents, and other manifest and bytecode-level features.

### Annotations

Labels are derived from VirusTotal multi-scanner verdicts. The `vendor_family_wide_verdict.csv` file preserves per-vendor family attributions to support research on label noise and disagreement.


## Considerations for Using the Data


### Social Impact

This dataset is intended for defensive cybersecurity research. It should not be used to develop offensive malware capabilities.

## Usage

### Loading Static Features

```python
import numpy as np
import json

# Load a specific year's training data
train_X = np.load("data_feature/processed_data/init_2013/2013/train_X.npz", allow_pickle=True)
train_meta = np.load("data_feature/processed_data/init_2013/2013/train_meta.npz", allow_pickle=True)

with open("data_feature/processed_data/init_2013/2013/vocab.json") as f:
    vocab = json.load(f)
```

### Loading Metadata

```python
import pandas as pd

metadata = pd.read_csv("metadata.csv")
verdicts = pd.read_csv("vendor_family_wide_verdict.csv")
```
