On January 17, 2024, the Canadian Centre for Cyber Security (the Centre) published an assessment titled “The Threat from Large Language Model Text Generators” (the Assessment), which draws on resources available to the Centre by virtue of its unique role in defending the Government of Canada’s information systems and uses those resources to provide valuable insight into adversary behaviour in cyberspace. The content of the Assessment is based on information available as of June 26, 2023.
Large language models (LLMs) are a form of generative artificial intelligence (AI) that can generate complete sentences or entire documents based on user-inputted prompts. The Assessment states that LLMs represent a growing and evolving threat to Canada’s information ecosystem as generative AI has become increasingly accessible to the public, cyber threat actors, and state-sponsored actors. For the current threat landscape, the Centre identifies the following to be the “most likely threats” from LLMs:
Conversely, the Centre assessed that the use of LLM text generators to create sophisticated/malicious code that could lead to a zero-day attack constitutes an “unlikely” threat. Similarly, while threat actors could inject or change data used to train newer versions of LLMs to maliciously undermine the accuracy and quality of the generated data (i.e., poisoning datasets), the Centre deems such threats to be “very unlikely” due to the large size and proprietary nature of the datasets.
Lastly, for organizations using LLM text generators, the Assessment identified certain associated risks that should be kept in mind, including: (i) data governance breaches, where unauthorized use of online tools may expose information to third parties and fail organizational data governance requirements; and (ii) the leaking of protected information (i.e., individuals providing input into LLM text generators may unknowingly leak sensitive information outside of approved organizational security frameworks).
