How to Backdoor Image Knowledge Distillation
New research shows knowledge distillation can transmit backdoors even from ostensibly clean teacher models, undermining a common safety assumption in ML supply chains.

arXiv:2504.21323v4 Announce Type: replace Abstract: Knowledge distillation is widely used to transfer behavior from a large teacher model to a smaller student. It is often assumed to be safe when the teacher is clean, because classic backdoor attacks rely on poisoned labels and triggers in supervised training, whereas distillation trains the student to match a teacher's outputs. We show that this assumption can fail when the distillation dataset itself is poisoned. Our attack injects triggered
Editorial Analysis
Organisations distilling large models for edge deployment may inherit hidden backdoors without detecting them via standard label-based integrity checks.
Audit model distillation workflows for integrity validation beyond label-poisoning detection.
