Researchers have identified and quantified a critical issue in continual learning for Android malware detection, termed "security regression." This phenomenon occurs when malware samples that were previously detected by a model evade detection after an update, even if the model's average performance has improved. Experiments revealed that up to 3-6% of malware samples can experience security regression. To address this, a new regression-aware framework, instantiated via Positive Congruent Training (PCT), has been developed. This method effectively halves security regression across various continual learning scenarios while maintaining strong detection performance over time. AI
