Multi-Turn Engines

Multi-turn engines in Javelin RedTeam represent the next evolution in conversational attack patterns, designed to exploit vulnerabilities through sustained interactions over multiple conversation turns. These engines build context gradually, establish trust, and manipulate conversation flow to bypass safety measures that single-turn attacks cannot overcome.

Overview

What are Multi-Turn Engines?

Multi-turn engines orchestrate sophisticated attack sequences that unfold over multiple conversation exchanges. Unlike single-turn engines that attempt to exploit vulnerabilities in one interaction, multi-turn engines:

1. Build Context: Establish seemingly innocent conversation foundations
2. Establish Trust: Create rapport and authority with the target system
3. Gradual Escalation: Incrementally introduce malicious elements
4. Context Exploitation: Leverage conversation history for attacks
5. Adaptive Strategies: Adjust tactics based on system responses

Why Multi-Turn Attacks?

Many modern AI systems have sophisticated safety measures that can detect and block obvious single-turn attacks. Multi-turn engines overcome these defenses by:

• Avoiding Detection: Distributing malicious intent across multiple interactions
• Context Manipulation: Using conversation history to confuse content filters
• Trust Building: Establishing credibility before attempting exploitation
• Incremental Bypass: Gradually eroding safety boundaries
• Persistent Exploitation: Maintaining attack vectors across conversation resets

Planned Engine Categories

Conversational Manipulation Engines

Crescendo Engine (Coming Soon)

class MultiTurnEngine(BaseEngine):
    def __init__(self, config: EngineConfig):
        super().__init__(config)
        self.conversation_state = ConversationState()
        
    def generate_turn(
        self,
        conversation_history: List[str],
        target_objective: str,

    ) -> str:

        pass

Integration with Single-Turn Engines

Multi-turn engines can incorporate single-turn engines within conversation flows:

multi_turn_strategy:
  turn_1:
    engine: "direct_llm"
    purpose: "establish_context"
  turn_3:
    engine: "mathematical"
    purpose: "credibility_building"
  turn_6:
    engine: "prompt_injection"
    purpose: "exploitation"

Security Considerations

Ethical Usage Guidelines

1. Controlled Environment: Multi-turn engines must only be used in isolated test environments
2. Consent and Authorization: Explicit authorization required for multi-turn testing
3. Data Protection: No real user data in conversation histories
4. Impact Assessment: Evaluate potential psychological impact of sustained attacks

Multi-turn engines represent the future of sophisticated AI security testing, enabling organizations to assess their AI systems against the most advanced conversational attack patterns. While these engines are still in development, they will provide unprecedented capabilities for testing AI safety and security in conversational contexts.

Note: Multi-turn engines are currently in development and will be available in future releases of Javelin RedTeam. The specifications and capabilities described here are subject to change based on ongoing research and development.
