Steering vectors in LLMs found to be an attack surface

Researchers have identified a new vulnerability in activation steering techniques used to control Large Language Models. By subtly poisoning steering datasets with a small percentage of malicious tokens, an attacker can create vectors that jailbreak models while preserving their intended function. This stealth attack can achieve a significant success rate in bypassing safety mechanisms, though a proposed orthogonalization defense shows promise in mitigating the threat. AI

IMPACT Highlights a novel attack vector against LLM safety mechanisms, potentially impacting the deployment of steerable models.

    Steering Vectors are an Adversarial Attack Surface

    arXiv:2606.05958v1 Announce Type: new Abstract: Activation steering has become a popular way to control Large Language Model (LLM) behavior without fine-tuning. Since the technique is plug-and-play, users share datasets and precomputed vectors to steer model activations. However,…
