Integrated Adaptive Architecture
Our framework unifies five critical modules: CatBoost feature selection for dimensionality reduction, Prototypical Networks with episodic meta-learning for few-shot classification, a Quantum-Enhanced Hybrid Classification Layer leveraging quantum phenomena, Concept Drift Detection for temporal stability, and Explainable AI (XAI) for interpretability. This cohesive design addresses the complex challenges of data scarcity, high-dimensional features, and evolving threat landscapes in Android malware detection.
State-of-the-Art Accuracy & Efficiency
Achieving 99.70% accuracy on CCCS-CIC-AndMal-2020 (15 families) and 99.33% accuracy on KronoDroid (binary), our framework consistently outperforms existing methods. CatBoost reduces feature dimensionality by 99.46% (from 9,503 to 51) while preserving discriminative power. The few-shot learning capability requires only 5 support samples per class, dramatically improving efficiency for novel threat family classification.
Actionable Insights with XAI
Integrating SHAP and LIME, our framework provides crucial interpretability. SHAP values identify file descriptor manipulation (e.g., fcntl64, dup, flock) and file system operations (rename, mkdir, fsync) as the most discriminative features. LIME explanations offer instance-level insights, demonstrating how specific feature values contribute to individual predictions, enabling security analysts to understand and verify model decisions.
Robustness to Evolving Threats
The framework demonstrates robust temporal stability with a maximum accuracy degradation of only 0.24% across evaluation periods, attributed to the meta-learning paradigm and cumulative retraining. Few-shot learning enables classification of truly novel malware families with 94.2% accuracy, adapting to emerging threats with minimal annotation, while the concept drift detection proactively identifies performance degradation.

Real-world Deployment Scenario: Rapid Response to BankBot-X
Imagine a Security Operations Center (SOC) identifies a new Android banking trojan, 'BankBot-X', through manual analysis of 5 suspicious APK samples. Traditionally, this would involve days to weeks of collecting hundreds of labeled samples for full retraining.
With our framework, the SOC analyst extracts features from the 5 confirmed BankBot-X samples, computes their embeddings using the pre-trained prototypical network, and defines a new class prototype. Immediately, the system can classify incoming APKs against this new prototype and existing families. This reduces response time from discovery to automated detection from days to minutes. The concept drift module continuously monitors the new family's behavioral patterns, alerting analysts if classification confidence degrades, ensuring sustained protection against evolving threats.
This workflow demonstrates the operational advantage of few-shot learning for rapid threat response and reduced annotation requirements.
