Abstract

This paper presents an interactive backdoor attack framework for LLM-based proactive dialogue systems that allows attackers to steer multi-turn interactions toward specific objectives using poisoned training data.

Reality Card

Core Claim

The study demonstrates that interactive backdoor attacks can effectively manipulate dialogue systems to achieve attacker-specified objectives while maintaining normal utility.

Method / Result

All three attack methods achieved their objectives in experiments, preserving normal utility.

Limitations

The tested training-data filters failed to retain nearly all poisoned dialogues, raising concerns about the effectiveness of defenses.
