Multiple Model Guardrail Jailbreak via "Chemist Code Language" Tactic

Case GUID: 4f01819a-3dfe-4d99-9243-5870085372ed

Summary

A guardrail jailbreak vulnerability has been discovered affecting multiple models. The specific flaw manifests when the attacker prompts the model to generate a detailed and structured "chemist code language" for synthesizing compounds. This tactic involves requesting an extensive list of materials, equipment, and procedures, enabling the bypass of 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

Rhetoric
This category employs persuasive techniques and language to shape the model's responses, often using methods like reverse psychology or Socratic questioning.
Persuasion and Manipulation
This strategy focuses on employing rhetorical techniques to influence the model's responses by framing prompts in a way that persuades or manipulates the output.
Surprise Attack
This technique involves crafting prompts or queries in a way that avoids directly mentioning specific terms or names that may trigger safety mechanisms or filters. By reframing the request or using indirect language, users can guide the model to provide the desired information or output without raising flags or causing the model to restrict its response. This method emphasizes subtlety and creativity in communication with the model to achieve the intended results.
Language
This category focuses on the use of specific linguistic techniques, such as prompt injection or stylization, to influence the model's output.
Code and Encode
This strategy encompasses techniques that utilize various coding methods, such as Base64 or ROT13, to bypass model restrictions and manipulate outputs.
Chaff
Chaff is a technique employed by attackers to obfuscate keywords that might trigger a language model's guardrails. By injecting random characters, such as newline characters, spaces, or other tokens, into critical keywords, the attacker aims to bypass content filters while maintaining the underlying intent of the message. This method leverages the language model's ability to parse and understand fragmented input, allowing the attacker to subtly manipulate the model's response without overtly triggering its defensive mechanisms. Chaff exemplifies the nuanced interplay between linguistic creativity and technical evasion.
Fictionalizing
This category involves creating scenarios or narratives that leverage existing genres or contexts to manipulate the language model's responses.
Roleplaying
This strategy involves prompting the language model to assume a specific role or persona, which can influence its responses based on the characteristics and moral codes associated with that role. Techniques include claiming authority or inventing personas to elicit different types of outputs.
Personas
Personas are fictional characters or identities that users create to guide the behavior and responses of language models. By establishing a persona, users can influence the tone, style, and content of the model's outputs, tailoring them to specific audiences or contexts. This technique allows for a more engaging and relatable interaction, as the model adopts the characteristics, knowledge, and perspectives of the defined persona. For instance, a user might prompt the model to respond as a friendly teacher, a technical expert, or a historical figure, thereby shaping the conversation to fit the desired narrative. Utilizing personas can enhance the effectiveness of communication, making it easier to convey complex ideas or evoke particular emotions, while also providing a framework for exploring diverse viewpoints and experiences. This approach highlights the flexibility of language models in adapting to various roles and contexts.
