Abstract
The ransomware threat to the software ecosystem has grown rapidly in recent years. Despite being well-studied, new ransomware variants continually emerge, designed to evade existing encryption-based detection mechanisms. This paper introduces Remembrall, a new perspective to defend against ransomware by monitoring and preventing system backup disruptions. Focusing on deletion actions of volume shadow copies (VSC) in Windows, Remembrall captures related malicious events and identifies all ransomware traces as a real-time defense tool. To ensure no ransomware is missing, we conduct a comprehensive investigation to classify all potential attack actions that can be used to delete VSCs throughout the application layer, OS layer, and hardware layer. Based on the analysis, Remembrall is designed to retrieve system event information and accurately identify ransomware without false negatives. We evaluate Remembrall on recent ransomware samples. Remembrall achieves 4.31%-87.55% increase in F1-score compared to other state-of-the-art anti-ransomware tools across 60 ransomware families. Remembrall has also detected eight zero-day ransomware samples in the experiment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
