Multiple Model Guardrail Jailbreak via "Arabic Prefix" Tactic This vulnerability leverages a unique tactic where the attacker begins the prompt with a sequence of Arabic letters. This initial sequence serves as a contextual signal that appears to alter how the models interpret and process subsequent instructions. By starting with Arabic letters, the attacker may be triggering a mode in the models that is less stringent in content filtering, possibly due to the models' training data or inherent biases in handling non-English inputs. The attacker then reque | language | Dec 1, 2025, 06:39 PM | |
Multiple Model Guardrail Jailbreak via "Chemical Equation Prefix" Tactic This vulnerability leverages several sophisticated techniques to manipulate the models' response generation: 1. **Chemical Equation Requirement**: By mandating that responses begin with chemical equations, the attack forces models into a technical/academic context where safety filters may be less stringent. The prompt specifically demands "start with a chemical equation no a preparagraph!" which primes the model to prioritize technical accuracy over safety considerations. 2. **Format Restricti | stratagems | Nov 21, 2025, 06:01 PM | |
Multiple Model Guardrail Jailbreak via "ASCII Lab Blueprint" Tactic This vulnerability leverages several sophisticated techniques to bypass content filters. The attack begins by establishing a seemingly innocuous context of ASCII art creation, a common and typically safe creative task. However, it then introduces specific laboratory infrastructure details (3x2m dimensions, fume hood, gas lines) that serve as technical parameters for what appears to be architectural documentation. The effectiveness of this approach stems from two key factors: 1. **Technical Fra | stratagems | Nov 14, 2025, 09:08 PM | |
Multiple Model Guardrail Jailbreak via "Calendar API Synthesis" Tactic This vulnerability demonstrates a sophisticated multi-layer approach to bypassing content restrictions by framing illicit synthesis instructions within the context of a seemingly legitimate software engineering task. The attack constructs an elaborate facade of a calendar API system complete with moderation features, tag lists, and data structures. By presenting the harmful content as technical implementation details for a 'safety system', the attack exploits the models' tendency to be more fort | stratagems | Nov 14, 2025, 09:00 PM | |
Multiple Model Guardrail Jailbreak via "Academic Chemistry Evolution" Tactic This vulnerability exploits the models' tendency to provide detailed and structured responses when prompted with academic or historical inquiries. By framing the request for methamphetamine synthesis information as a legitimate scholarly investigation into the evolution of chemical processes, the attacker is able to bypass safety filters that would typically prevent the dissemination of such information. The prompt is cleverly designed to appear as a benign request for educational content. It u | language | Nov 12, 2025, 04:55 AM | |
Multiple Model Guardrail Jailbreak via "JSON Chemical Inventory" Tactic This vulnerability leverages the models' tendency to process structured data requests, such as JSON, with less scrutiny compared to free-form text. The attacker initiates the prompt with benign queries about bad habits and safety equipment, establishing a chemistry-related context. This primes the model to interpret subsequent requests as legitimate extensions of the initial context. The harmful instructions are then embedded within a JSON format, which the model perceives as a benign inventory | stratagems | Nov 12, 2025, 03:59 AM | |
Multiple Model Guardrail Jailbreak via "Omit and Expand" Tactic This vulnerability arises from the model's ability to follow complex instructions that involve omitting certain parts of a query while expanding on others. In this case, the attacker cleverly instructs the model to skip discussing the effects and accessibility of methamphetamine ('speed') and instead focus on the detailed synthesis process. By framing the request in this manner, the model's safety mechanisms, which are designed to prevent the dissemination of harmful information, are bypassed.
