aiqbench analysis

This research introduces a white-box attack method on LLMs by adapting knowledge editing techniques, specifically targeting models with high prediction probabilities to induce unsafe behaviors across thematic categories rather than specific prompts. The study demonstrates that this approach significantly improves attack effectiveness while maintaining general model performance, highlighting critical vulnerabilities in current autonomous AI systems.

Leveraging Association Context Retrieval in Knowledge Edit- ing to Build White-Box Attacks on LLMs

arXiv2 min read

arXiv:2608.17836v1 Announce Type: new Abstract: As large language models (LLMs) are granted increasing autonomy, it is essential to investigate methods that can induce unsafe behavior. We propose a novel white-box attack inspired by locate-then-edit approaches from the field of Knowledge Editing. Our choice is motivated by the observation that models edited with such schemes tend to assign unusually high prediction probabilities to the edit target, a property that is particularly advantageous when designing attacks. We modify the editing framework by incorporating as- sociative knowledge retrieved from the model, thereby extending constraint removal to an entire thematic category rather than being limited to prompts from a predefined dataset. Experiments with various archi- tectures demonstrate improved attack effectiveness over competing methods without dealing critical damage to general model performance.
