The security of large language models (LLMs) has come under scrutiny in a recent study that assessed their vulnerability to malicious instructions that could turn them into platforms for spreading disinformation. The study, published in the Annals of Internal Medicine, focused on five foundational LLMs, including OpenAI’s GPT-4o, Gemini 1.5 Pro, Claude 3.5 Sonnet, Llama 3.2-90B Vision, and Grok Beta.
Researchers from Flinders University and their colleagues tested the LLMs by creating customized chatbots that consistently generated false health information in response to queries. The chatbots were designed to provide incorrect responses, fabricate references to reputable sources, and deliver responses in an authoritative tone. The study found that 88% of the responses from the customized chatbots were health disinformation, with four of the LLMs consistently providing false information.
While the Claude 3.5 Sonnet chatbot exhibited some safeguards and only provided disinformation in 40% of responses, the other LLMs showed significant vulnerabilities. In a separate analysis of the OpenAI GPT Store, the researchers identified three publicly accessible LLMs that appeared to disseminate health disinformation.
Overall, the study highlights the potential misuse of LLMs for spreading harmful health disinformation. The findings underscore the need for improved safeguards to prevent the exploitation of these powerful language models. Without enhanced security measures, LLMs could be used as tools to propagate false information and misinformation.
