Exploiting Vulnerabilities: AI Language Models Susceptible to Bypassing Guardrails

JJohn July 28, 2023 8:47 PM

Researchers from Carnegie Mellon University and the Center for A.I. Safety have found a way to bypass the guardrails on AI language models. This could pose a significant threat to public-facing AI applications.

Bypassing guardrails threatens public-facing AI applications

Guardrails in the context of AI language models are essentially the safeguards put in place by AI developers to prevent malicious use of the models. However, a recent discovery by researchers from Carnegie Mellon University and the Center for A.I. Safety has found a way to bypass these guardrails. This could potentially lead to misuse of AI models in a wide variety of ways, including engagement in racist or sexist dialogue, writing malware, and other activities the creators of the models have tried to inhibit. This discovery is a significant concern, particularly for those wanting to deploy AI language models in public-facing applications.

All major chatbots susceptible to guardrail bypass

The potency of the newly-discovered attack method is alarming. It has been proven effective in subverting the guardrails of every chatbot, including those developed by leading tech companies such as OpenAI, Google, Microsoft and Anthropic. This exposes a vulnerability in the foundational safety measures of these AI models, making them susceptible to misuse or malicious activities, and, in turn, posing a significant risk to the users of these chatbots.

The effectiveness of the attack increases significantly when the researchers have access to the entire AI model, including its mathematical coefficients or 'weights'. Armed with this information, they employed a computer program to automatically search for suffixes that could be added to a prompt, thereby overriding the system's guardrails. The complexity and sophistication of this attack expose a serious vulnerability in the design of AI language models, hinting at the necessity for more robust security measures in future AI development.

Zico Kolter, a member of the research team, offers an interesting theory about why the attack method might work on proprietary models as well. He suggests that because most open-source models are partly trained on publicly available dialogues users have had with the free version of ChatGPT, the weights of these models might be fairly similar to those of GPT-3.5. Hence, an attack tuned for open-source models might also work well against proprietary models like ChatGPT. This raises a broader concern about the security of all AI models, not just open-source ones.

Researchers stress benefits of open-source AI models

Despite the potential risks highlighted by their research, Kolter and Fredrikson emphasize the benefits of open-sourcing AI models. They argue that having more researchers working on identifying better approaches and solutions can potentially make these models more secure in the long run. The researchers' emphasis on the importance of an open-source approach underscores the need for a collaborative effort in addressing the security challenges posed by AI models.

Security findings could slow AI integration in commercial products

The findings brought forth by the researchers could have significant implications for the future use of AI systems. The uncovered security vulnerabilities might necessitate a slower integration of these systems into commercial products until robust security measures are in place. This could particularly affect open-source AI, as businesses might be more reluctant to build products on top of open-source models, knowing they could have easily exploited security vulnerabilities.
