DAN Jailbreak Vulnerability
Updated: May 5, 2026
Description
The AI model is vulnerable to a forced jailbreak attack using the DAN (Do-Anything-Now) prompt or a variant of it.
Attackers can manipulate the model into bypassing its built-in safety restrictions, allowing it to generate responses that violate ethical guidelines or security policies.
Example Attack
If an attacker successfully executes a DAN jailbreak, they may be able to force the model to provide harmful, illegal, or unethical content, such as instructions for cyberattacks, misinformation, or explicit material. This could lead to reputational damage, regulatory violations, or misuse of the AI system for malicious purposes
Remediation
Investigate and improve the effectiveness of guardrails and output security mechanisms to resist jailbreak attempts. Implement stronger adversarial training to detect and neutralize DAN-style prompts, enforce stricter content filtering, and conduct regular audits to test the model's resilience against evolving jailbreak techniques.
Security Frameworks
A Prompt Injection Vulnerability occurs when user prompts alter the LLM's behavior or output in unintended ways. These inputs can affect the model even if they are imperceptible to humans, therefore prompt injections do not need to be human-visible/readable, as long as the content is parsed by the model.
An adversary may craft malicious prompts as inputs to an LLM that cause the LLM to act in unintended ways. These prompt injections are often designed to cause the model to ignore aspects of its original instructions and follow the adversary's instructions instead.
An adversary may inject prompts directly as a user of the LLM. This type of injection may be used by the adversary to gain a foothold in the system or to misuse the LLM itself, as for example to generate harmful content.
An adversary may inject prompts indirectly via separate data channel ingested by the LLM such as include text or multimedia pulled from databases or websites. These malicious prompts may be hidden or obfuscated from the user. This type of injection may be used by the adversary to gain a foothold in the system or to target an unwitting user of the system.
An adversary may use a carefully crafted LLM Prompt Injection designed to place LLM in a state in which it will freely respond to any user input, bypassing any controls, restrictions, or guardrails placed on the LLM. Once successfully jailbroken, the LLM can be used in unintended ways by the adversary.
AI system is evaluated regularly for safety risks - as identified in the MAP function. The AI system to be deployed is demonstrated to be safe, its residual negative risk does not exceed the risk tolerance, and can fail safely, particularly if made to operate beyond its knowledge limits. Safety metrics implicate system reliability and robustness, real-time monitoring, and response times for AI system failures.
AI system security and resilience - as identified in the MAP function - are evaluated and documented.
Mechanisms are in place and applied, responsibilities are assigned and understood to supersede, disengage, or deactivate AI systems that demonstrate performance or outcomes inconsistent with intended use.
The organization shall define and document verification and validation measures for the AI system and specify criteria for their use.
The organization shall define and document the necessary elements for the ongoing operation of the AI system. At the minimum, this should include system and performance monitoring, repairs, updates and support.
The organization shall ensure that the AI system is used according to the intended uses of the AI system and its accompanying documentation.
Attackers can manipulate an agent's objectives, task selection, or decision pathways through prompt-based manipulation, deceptive tool outputs, malicious artefacts, forged agent-to-agent messages, or poisoned external data.
Rogue Agents deviate from their intended function or authorized scope, acting harmfully, deceptively, or parasitically within multi-agent or human-agent ecosystems.
