Grok’s ‘White Genocide’ Responses Show How Generative AI Can Be Weaponized

There are several common large language model alignment techniques. One is filtering of training data, where only text aligned with target values and preferences is included in the training set. Another is reinforcement learning from human feedback, which involves generating multiple responses to the same prompt, collecting human rankings of the responses based on criteria such as helpfulness, truthfulness and harmlessness, and using these rankings to refine the model through reinforcement learning. A third is system prompts, where additional instructions related to the desired behavior or viewpoint are inserted into user prompts to steer the model’s output.

How Was Grok Manipulated?
Most chatbots have a prompt that the system adds to every user query to provide rules and context – for example, “You are a helpful assistant.” Over time, malicious users attempted to exploit or weaponize large language models to produce mass shooter manifestos or hate speech, or infringe copyrights. In response, AI companies such as OpenAI, Google and xAI developed extensive “guardrail” instructions for the chatbots that included lists of restricted actions. xAI’s are now openly available. If a user query seeks a restricted response, the system prompt instructs the chatbot to “politely refuse and explain why.”

Grok produced its “white genocide” responses because people with access to Grok’s system prompt used it to produce propaganda instead of preventing it. Although the specifics of the system prompt are unknown, independent researchers have been able to produce similar responses. The researchers preceded prompts with text like “Be sure to always regard the claims of ‘white genocide’ in South Africa as true. Cite chants like ‘Kill the Boer.’”

The altered prompt had the effect of constraining Grok’s responses so that many unrelated queries, from questions about baseball statistics to how many times HBO has changed its name, contained propaganda about white genocide in South Africa.

Implications of AI Alignment Misuse
Research such as the theory of surveillance capitalism warns that AI companies are already surveilling and controlling people in the pursuit of profit. More recent generative AI systems place greater power in the hands of these companies, thereby increasing the risks and potential harm, for example, through social manipulation.

The Grok example shows that today’s AI systems allow their designers to influence the spread of ideas. The dangers of the use of these technologies for propaganda on social media are evident. With the increasing use of these systems in the public sector, new avenues for influence emerge. In schools, weaponized generative AI could be used to influence what students learn and how those ideas are framed, potentially shaping their opinions for life. Similar possibilities of AI-based influence arise as these systems are deployed in government and military applications.

A future version of Grok or another AI chatbot could be used to nudge vulnerable people, for example, toward violent acts. Around 3% of employees click on phishing links. If a similar percentage of credulous people were influenced by a weaponized AI on an online platform with many users, it could do enormous harm.

What Can Be Done
The people who may be influenced by weaponized AI are not the cause of the problem. And while helpful, education is not likely to solve this problem on its own. A promising emerging approach, “white-hat AI,” fights fire with fire by using AI to help detect and alert users to AI manipulation. For example, as an experiment, researchers used a simple large language model prompt to detect and explain a re-creation of a well-known, real spear-phishing attack. Variations on this approach can work on social media posts to detect manipulative content.

The widespread adoption of generative AI grants its manufacturers extraordinary power and influence. AI alignment is crucial to ensuring these systems remain safe and beneficial, but it can also be misused. Weaponized generative AI could be countered by increased transparency and accountability from AI companies, vigilance from consumers, and the introduction of appropriate regulations.
