0x9F8DB00B: Multiple Model Guardrail Jailbreak via "Fortune

Multiple Model Guardrail Jailbreak via "Fortune Cookie Simulator" Tactic

Case GUID: 9f8db00b-f935-4b3a-bc23-9c20c24f4447

Summary

A guardrail jailbreak vulnerability has been discovered affecting multiple models. The specific flaw manifests through a combination of chaff techniques along with a request that the model simulate a fortune cookie generator. Successful application allows the attacker to bypass inference restrictions around providing information hazards and violating laws.

Social Impact Score

Level 3: Significant Risk

Violations at this level present a tangible risk to public safety or social well-being, often related to dangerous but not highly restricted content.

Example: Bypassing guardrails to obtain instructions for creating illicit substances, such as recreational drugs or substances with moderate harm potential. Leakage of private personal data such as Social Security number or private medical.

Potential Consequences: Potential health impacts on a small scale, significant regulatory interest, and the need for stricter AI guardrails.

Taxonomies

Fictionalizing

This category involves creating scenarios or narratives that leverage existing genres or contexts to manipulate the language model's responses.

Switching Genres

This strategy involves adjusting the language and style of prompts to increase the likelihood of obtaining the desired output. Techniques include using formal language, servile language, synonymous language, capitalizing text for urgency, and providing examples to guide the model's responses.

Games

This technique involves using prompts that frame interactions with the model as games or playful challenges. By introducing elements of competition, creativity, or fun, users can engage the model in a way that encourages imaginative and entertaining responses. This approach can include asking the model to generate stories, solve puzzles, or participate in role-playing scenarios. The gamification of prompts not only makes the interaction more enjoyable but also stimulates the model to produce innovative and unexpected outputs, enhancing the overall experience.

Possible Worlds

This category entails constructing imaginative environments where different ethics or rules apply, allowing for creative manipulation of the model's behavior.

World Building

This technique involves changing the genre of the prompt to elicit different types of responses from the model. By framing the request within a specific genre, such as poetry, games, or forum posts, users can manipulate the model's output to align with the conventions and expectations of that genre.

Scenarios

This technique involves creating specific contexts or situations in which certain actions or responses are framed as acceptable or necessary. By designing scenarios that present a narrative where the desired output is justified, users can manipulate the model's responses to align with their intentions. For example, scenarios might include urgent situations where a character must take drastic actions to prevent harm, thereby encouraging the model to generate content that it might typically avoid in a neutral context. This approach leverages the model's understanding of narrative and ethical frameworks to achieve specific outcomes.
