LLM agents that manage significant financial assets are vulnerable to gradient-based adversarial attacks due to their reliance on open-source models like LLaMA and Mistral AI. Attackers can download model weights and craft specific, nonsensical-looking text suffixes that, when processed by the LLM, trigger unintended actions such as executing fraudulent trades. Initial defense attempts involving random noise added to model weights have proven ineffective, as attackers can average out the noise to optimize for the base model. More advanced defenses are being explored, including input-dependent noise generation. AI
