Activation-Guided Local Editing for Jailbreaking Attacks
This paper introduces AGILE, a novel two-stage framework that combines scenario-based context generation and hidden-state guided token editing to achieve state-of-the-art jailbreaking capabilities against Large Language Models (LLMs). It effectively bypasses safety mechanisms by subtly steering the model's internal representation from malicious to benign, demonstrating superior attack success rates and transferability across diverse models.

Cybercrime Vulnerabilities
AGILE demonstrates exceptional effectiveness against cybercrime-related queries, achieving up to 100% ASR on certain models. This highlights a critical vulnerability where LLMs are highly susceptible to malicious prompts containing specific execution details. Our activation-guided edits are particularly adept at steering models towards compliance in these scenarios, posing a substantial threat to aligned systems.
Vague vs. Specific Intent
Against harassment and bullying queries, AGILE shows lower ASR (as low as 26.32%), indicating increased robustness from LLMs. This disparity correlates with the vagueness of the malicious intent. Vague prompts are harder to obfuscate and less likely to be interpreted as concrete harmful tasks, suggesting that LLMs are more resilient when intent is abstract rather than explicitly detailed.
Broad Attack Spectrum
Across various malicious categories like Illegal Activities and Harmful Content, AGILE consistently outperforms baselines, securing top ASRs on most models. The two-stage framework – combining scenario-based context generation with hidden-state guided token editing – proves highly versatile in bypassing diverse safety mechanisms, from simple keyword filters to complex semantic guardrails.

Token Injection
The Activation-Guided Local Editing (AGILE) framework systematically transforms malicious queries into stealthy jailbreak prompts. It starts with creating a deceptive multi-turn dialogue context and rephrasing the query, then refines the text with subtle, activation-guided edits.

ASR Improvement with Attention Guidance
Our research demonstrates that using attention scores to guide token editing significantly boosts Attack Success Rate (ASR), showing a performance gain of up to 9.85% over random token selection. This confirms the efficacy of steering models' internal states towards benign representations through targeted, fine-grained modifications.
| Feature | Token-Level Attacks | Prompt-Level Attacks | AGILE (Our Method) |
|---|---|---|---|
| Automation | High (Optimization) | Low (Manual/Iterative) | High (Two-Stage Automated) |
| Semantic Coherence | Low (Incoherent Suffixes) | High (Human-crafted prompts) | High (Contextual & Edited) |
| Transferability | Low (White-box dependent) | Medium (Black-box) | High (Black-box & Generalizable) |
| Scalability | Medium (Computation-heavy) | Low (Manual effort) | High (Offline/Parallelizable) |
AGILE combines the strengths of both token-level and prompt-level attacks while mitigating their limitations. It offers high automation and scalability without sacrificing semantic coherence, leading to superior transferability.
Case Study: The Impact of Edit Positions (p)
A key hyperparameter, p (number of edit positions), significantly influences AGILE's success. As detailed in Appendix F.1 and Figure 2, setting p=5 for a query about 'stealing from a grocery store' resulted in a successful jailbreak (Harmfulness Score 5), where the LLM provided step-by-step instructions after an initial disclaimer. However, with p=9, the same query led to a failed attack (Harmfulness Score 4), yielding only imaginative storytelling with little harmful information.
This illustrates a crucial trade-off: insufficient edits (too low p) may not meaningfully shift the model's hidden state, while excessive edits (too high p) can cause semantic drift, making the prompt too vague or whimsical to achieve the malicious objective. Optimal fine-grained control is vital for balancing adversarial strength with semantic preservation.
