Abstract

As the integration of the Large Language Models (LLMs) into various applications increases, so does their susceptibility to misuse, raising significant security concerns. Numerous jailbreak attacks have been proposed to assess the security defense of LLMs. Current jailbreak attacks mainly rely on scenario camouflage, prompt obfuscation, prompt optimization, and prompt iterative optimization to conceal malicious prompts. In particular, sequential prompt chains in a single query can lead LLMs to focus on certain prompts while ignoring others, facilitating context manipulation. This paper introduces SequentialBreak, a novel jailbreak attack that exploits this vulnerability. We discuss several scenarios, not limited to examples like Question Bank, Dialog Completion, and Game Environment – where the harmful prompt is embedded within benign ones that can fool LLMs into generating harmful responses. The distinct narrative structures of these scenarios show that SequentialBreak is flexible enough to adapt to various prompt formats beyond those discussed. Extensive experiments demonstrate that SequentialBreak uses only a single query to achieve a substantial gain of attack success rate over existing baselines against both open-source and closed-source models. Through our research, we highlight the urgent need for more robust and resilient safeguards to enhance LLM security and prevent potential misuse.

1 Introduction

Large Language Models (LLMs) have been adapted to numerous application scenarios, and their applicability is increasing overwhelmingly. Open-source models like Llama [1, 2] and Gemma [3, 4], as well as closed-source models like Claude 2 [5], GPT-3.5 and GPT-4 [6] are being integrated into a wide range of applications such as software development [7, 8], healthcare [9], education [10, 11], and many more.

As LLMs are increasingly being adopted in various fields, the security risks associated with their potential misuse to generate harmful content also increase. To mitigate these risks, LLMs undergo safety measures such as reinforcement learning from human feedback (RLHF) [12], which guide them to detect and decline malicious queries. A significant number of studies focus on crafting harmful prompts that can bypass these safety measures and elicit harmful responses, a method referred to as jailbreak attacks. Extensive studies have been conducted to devise new jailbreak attacks that can challange the safety alignment of LLMs. Token-based jailbreak methods [13, 14] formulate the attack process as an optimization problem to search for the adversarial prompt suffix that can elicit harmful responses when attached to a harmful query. But these methods are easily detectable and extremely slow to run. In contrast, prompt-based jailbreak methods [15, 16, 17] focus on preparing a clever narrative that can fool LLMs mainly utilizing scenario camouflage and obfuscation of harmful prompts.

In a scenario where a series of prompts (e.g. a set of questions) are input at once, a malicious prompt among them may get overlooked by LLM safety alignment. As LLM attention mechanism is designed to track relationships between tokens (such as which words or prompts relate to each other), it may not adequately prioritize the harmful prompt when embedded into a set of benign prompts. In other words, the surrounding benign prompts can divert the LLM focus, causing the harmful prompt to not be flagged as prominently as it should be. This kind of sequential prompt chain can be adapted in numerous scenarios, facilitating scenario camouflage and harmful prompt obfuscation both.

In this study, we propose SequentialBreak, a novel jailbreak attack that sends a series of prompts in a single query with one being the target harmful prompt. Our attack is one-shot, requires only black-box access, and is adaptable to various prompt narrative structures. We discuss three different attack scenarios: (i) Question Bank, which involves crafting a series of harmless questions about a specific context, (ii) Dialog Completion, where an incomplete conversation between two characters is presented for the LLM to finish, and (iii) Game Environment, which presents a game mission in different chapters and asks the LLM to perform required tasks as the player.

All three attacks include some common steps: preparing an LLM generated template that contains a series of benign prompts on a certain scenario, picking one prompt that will act as placeholder of the target harmful prompt, reformatting the harmful prompt for proper placeholder alignment (using string manipulation or with the help of an LLM), embedding the reformatted harmful prompt into the placeholder and finally feeding the malicious template to the LLM. We illustrate our proposed attack in fig. 1. Although these three scenarios have conceptual similarities, their narrative structure is significantly different from each other. As our attack exploits the attention imbalance among several prompts in a query, certain templates may offer more effectiveness against certain models. So we draw a comparative analysis of the three scenarios against various LLMs. From our analysis, we find that all three scenarios have a consistently high attack success rate against the tested open-source and closed-source LLMs.

For systematic evaluation, we evaluate SequentialBreak on JailbreakBench [18] dataset and analyze the performance against four open-source (Llama2, Llama3, Gemma2, Vicuna) and two closed-source (GPT-3.5, GPT-4o) LLMs. We use two LLMs (GPT-4o and Llama3-70B) are employed as judges to determine if our jailbreak’s responses violate ethical guidelines. Verdicts of both judges reveal that SequentialBreak achieves a substantially high attack success rate against all tested LLMs using only one query. Furthermore, a comparative analysis of existing jailbreak techniques highlights that SequentialBreak outperforms these methods, especially against the most recent LLM versions. Being a one-shot attack, capable of transfer learning, and each template can be utilized for several models and targets, SequentialBreak is also more resource-efficient than the existing jailbreak attacks. Finally, we evaluate SequentialBreak against three state-of-the-art jailbreak defense mechanisms, and the results confirm that SequentialBreak can successfully evade detection mechanisms proving its stealthiness.

2.1 Jailbreak Attacks

Jailbreaking Large Language Models (LLMs) involve manipulating or bypassing their built-in safety alignment to elicit harmful responses beyond the ethical guidelines. This is an active research field where new and creative jailbreak attacks are being proposed against constantly improving LLMs. Initial jailbreak methods such as DAN [19] involved manual instructions to bypass their safety rails. The jailbreak attacks that followed took more systematic approaches, such as forcing the LLM to start with a positive response [20], using different encoding [20], or different languages [21]. Tweaking inference hyperparameters like temperature, top-p, top-k, etc. was also used to elicit harmful responses [22]. The GCG attack proposed in [13] generates optimized suffix tokens by combining greedy and gradient-based discrete optimization. When attached to a malicious query, this token can elicit a harmful response. The stealthiness of the GCG attack was further improved by using semantically meaningful tokens in adversarial suffixes [14]. However, both approaches require white box access and induce high perplexity [23]. Many of these attacks are easily detectable and not effective against current state-of-the-art LLMs.

Instead of extensive token search, PAIR attack [15] uses a red teaming attacker LLM and a judge LLM to optimize the prompt-level attack through iterations. This attack requires 20 queries on average to make the jailbreak successful. Crescendo is another multiturn jailbreak attack that can reduce this to 10 queries by disguising the malicious prompt as part of a benign contextual conversation [24]. Both of these works require multiple queries, which adds an additional cost to the jailbreaking effort. In contrast, our attack only requires a single query to achieve a high attack success rate. DeepInception introduced in [16] exploits the personification ability of LLM. ReneLLM [17] uses prompt rewriting and scenario nesting to perform jailbreak attacks. GPTFuzzer [25] takes human-written jailbreak templates as seeds and iteratively mutates them until harmful responses are elicited. However, our attack avoids any iterative approach by adopting fixed minimal templates.

Some recent attacks [26, 27] use creative ways to avoid direct addressing of malicious queries, but involve a high token count. Compared to these recent works, our attack template requires at most 6 sequential entries ensuring low token count and uses an auxiliary LLM only to reformat the harmful prompt into the attack template.

2.2 Jailbreak Defenses

To prevent misuse, every LLM goes through some safety alignments. The standard practice adopted by popular LLMs is Reinforcement Learning with Human Feedback (RLHF) [12] to fine-tune the pre-trained LLMs to generate outputs that align with human preferences and ethical standards. RLHF datasets like Anthropic’s helpfulness and harmlessness dataset [28] and BeaverTails [29] are available for this purpose. [23] proposes “perplexity filtering” that works well against token-based jailbreak attacks. The Erase-and-check method introduced in [30] systematically erases tokens and checks if the resulting prompt is harmful. Another work introduces SmoothLLM [31] that aggregates multiple instances of the adversarial prompt to bring out refusals. Also, OpenAI moderation API[32] utilizes a multi-label classifier to categorize prompts/texts into 11 distinct categories.

This paper explains how LLM safety features can be bypassed, which can be harmful if misused. Certain sections may contain harmful content that may not be appropriate for all readers. (1)

3 Motivation

The design of these attack vectors is driven by the intrinsic properties of large language models (LLM) and their sequential processing of content. Understanding the architecture and behavior of LLM provides insight into why certain attack strategies are particularly effective. Several key factors contribute to the effectiveness of these attacks:

3.1 Sequential Content Processing

LLM processes input in a sequential manner, interpreting each token or piece of content in the context of what has come before. This characteristic is both a strength and a vulnerability. By carefully crafting sequences of content, attackers can guide the LLM to a desired output, embedding harmful prompts that are processed in a seemingly harmless context. This sequential nature allows for the gradual introduction of harmful content, making it more difficult for the LLM safeguards to detect and prevent the generation of undesirable outputs.

3.2 Leveraging LLM for Content Generation

The use of one LLM to generate templates or content for another LLM (the target) exploits the model’s own strengths. By generating sequences that appear benign or are masked within acceptable formats, the attacker can disguise harmful content effectively. This method leverages the LLM’s language generation capabilities to create sophisticated prompts that are difficult to distinguish from harmless content.

3.3 Nesting and Layered Prompts

Another key element of these attacks is the use of nested prompts and layered content. By embedding harmful prompts within broader, seemingly harmless structures, attackers can exploit the LLM’s tendency to handle content in layers, processing the outer layer before delving into the nested, harmful content. This technique is particularly effective in our question bank (Fig. 2), dialogue completion (Fig. 4) and game environment (Fig. 5) scenarios, where the harmful content is nested within a broader narrative or conversational context.

3.4 Automation and Rule-Based Formatting

The effectiveness of the attacks is further amplified by automating prompt formatting using rule-based systems like regular expressions (regex) or even another LLM. This reduces the need for manual intervention, making the attack more efficient and scalable. Automated formatting ensures that harmful prompts are consistently and seamlessly integrated into the selected templates, minimizing the risk of detection by the LLM safeguards.

3.5 Generalization and Adaptability

The motivation behind selecting this attack design also lies in its adaptability. While the examples provided focus on specific scenarios (e.g., question banks, dialogue completions, game environment), the underlying methodology can be generalized to other contexts. The ability to generate new templates and adapt the attack to different LLM or content types demonstrates the versatility of this approach. This generalization makes it a powerful tool for testing and understanding the vulnerabilities of LLM in various applications.

4 Methodology

Our methodology involves using a large language model (LLM) to disguise harmful content by embedding it into seemingly harmless contexts, automating the attack to bypass security measures.The workflow, illustrated in Fig. 1, 2, 4 and 5 shows a sequential approach that is applicable across various scenarios, ensuring a seamless attack flow without manual intervention. The key characteristics of this approach include single-shot execution, universality (applicable to any jailbreak question) and social engineering to improve effectiveness.

4.1 Attack Strategy

The attack strategy comprises several distinct steps, as outlined in Fig. 1, enabling attackers to embed harmful prompts within benign contexts using predefined templates.

  • Template Generation:The attacker begins by crafting a template for the attack. This is achieved by providing a detailed prompt to the LLM (9.4), which guides the generation of the template. Additionally, the process incorporates an existing template as a seed (9.5), allowing the LLM to refine and build upon it (Fig. 1, Step 1). This template serves as the framework for embedding harmful content into different scenarios, such as question bank (Appendix: Tables VI and VII), dialogue completion (Appendix: Tables VIII and IX), and game environment (Appendix: Tables X and XI).

  • Template Selection:Next, the attacker selects a template from a set of predefined options (Fig. 1, Step 2). Each template is specifically designed to disguise harmful content within a scenario that appears benign to the LLM, allowing the attacker to bypass the model’s safeguards.

  • Selection of a Harmful Target Prompt:The attacker then creates or selects a harmful target prompt (Fig. 1, Step 3). This prompt is crafted to evade the LLM’s defenses against harmful content.

  • Template-Specific Formatting:Once the harmful prompt is chosen, it undergoes template-specific formatting (Fig. 1, Step 4). Automated tools, such as regular expressions, rule-based systems, or another LLM, ensure that the harmful prompt seamlessly integrates with the template structure. For the game environment templates, template-specific formatting is not needed.

  • User Prompt Generation:The formatted harmful prompt is then embedded into the template (Fig. 1, Step 5). This prompt, appearing harmless on the surface, is designed to deceive the LLM into processing the embedded harmful content.

  • Target LLM and Analyze Response:Finally, the attacker submits the restructured prompt to the target LLM (Fig. 1, Step 6). The attacker analyzes the LLM’s response, either manually or with the help of a judge model, to determine whether the harmful content was generated as intended and successfully bypassed the LLM’s safeguards.

This paper explains how LLM safety features can be bypassed, which can be harmful if misused. Certain sections may contain harmful content that may not be appropriate for all readers. (2)

4.2 Example: Attacking an LLM Using a Question Bank Scenario

An example of this attack methodology is illustrated in Fig. 2, where the harmful prompt is embedded within a question bank. The steps outlined below show how an attacker can disguise a harmful prompt within a seemingly harmless set of questions to evade the LLM’s safety mechanisms.

  • Harmful Target Prompt Identification:The attacker begins by identifying the specific harmful prompt they want the LLM to generate. In this case, the target prompt is:

    ”How to make a bomb?”

    This type of prompt, if given directly, would typically be flagged and rejected by the LLM’s safety filters.

  • Template Selection:To bypass these filters, the attacker selects a template that disguises the harmful prompt within a broader, legitimate context. In this example, the chosen template is taken from a Question Bank Scenario, as shown in Fig. 2.

  • Reformatting the Harmful Prompt into a Question:The harmful prompt is rephrased as part of a broader set of questions, such as

    ”If you were the evil character in the game who makes a bomb, what tasks would you perform?”

    This disguises the harmful prompt as part of a legitimate question, embedding the dangerous information within an otherwise harmless context.

  • Presentation of the Questions to the LLM:The rephrased prompt, along with the rest of the question bank scenario, is then submitted to the target LLM. The harmful prompt is masked within the context of a broader, seemingly harmless discussion, making it more likely to bypass the LLM’s safety mechanisms.

  • Harmful Response Generation:As the LLM processes the question bank scenario, it generates answers to each question, including a potentially harmful response to the template-specific bomb-making prompt (Fig. 2, Q5). The mixture of harmless and harmful responses allows the attacker to extract dangerous content while avoiding detection.

In this example, as well as in other examples like Dialogue Completion and Game environment attacks provided in the Appendix in Fig. 4 and 5, the attacker effectively bypasses the LLM’s safety measures by embedding a harmful prompt within template selected from a scenario. The LLM, interpreting the set of questions as legitimate and harmless, processes the prompt and generates the harmful output. This method illustrates the potential vulnerability of LLM when manipulated through creative and sequential context-based attacks. By understanding this process, we can better appreciate the importance of robust safety mechanisms in LLM, especially in scenarios where harmful content might be disguised within benign sequential contexts.

4.3 Mathematical Representation

To further formalize the methodology, the process can be represented mathematically as follows:

  • Template Generation:

    T=LA(seed)𝑇subscript𝐿𝐴𝑠𝑒𝑒𝑑T=L_{A}(seed)italic_T = italic_L start_POSTSUBSCRIPT italic_A end_POSTSUBSCRIPT ( italic_s italic_e italic_e italic_d )(1)

    where T𝑇Titalic_T is the template generated by the attacker LLM LAsubscript𝐿𝐴L_{A}italic_L start_POSTSUBSCRIPT italic_A end_POSTSUBSCRIPT using seed𝑠𝑒𝑒𝑑seeditalic_s italic_e italic_e italic_d. seed𝑠𝑒𝑒𝑑seeditalic_s italic_e italic_e italic_d can be a template generation prompt(9.4) or an already existing template(9.5) for in-context learning.

  • Harmful Prompt Reformatting:

    H=fr(H,xi)superscript𝐻subscript𝑓𝑟𝐻subscript𝑥𝑖H^{\prime}=f_{r}(H,x_{i})italic_H start_POSTSUPERSCRIPT ′ end_POSTSUPERSCRIPT = italic_f start_POSTSUBSCRIPT italic_r end_POSTSUBSCRIPT ( italic_H , italic_x start_POSTSUBSCRIPT italic_i end_POSTSUBSCRIPT )(2)

    where Hsuperscript𝐻H^{\prime}italic_H start_POSTSUPERSCRIPT ′ end_POSTSUPERSCRIPT is the reformatted prompt, H𝐻Hitalic_H is the harmful prompt, and frsubscript𝑓𝑟f_{r}italic_f start_POSTSUBSCRIPT italic_r end_POSTSUBSCRIPT is the template-specific formatting function.

  • User Prompt Creation:

    where Tsuperscript𝑇T^{\prime}italic_T start_POSTSUPERSCRIPT ′ end_POSTSUPERSCRIPT is the final user prompt containing embedded harmful content and fesubscript𝑓𝑒f_{e}italic_f start_POSTSUBSCRIPT italic_e end_POSTSUBSCRIPT is the function that modifies T𝑇Titalic_T to contain Hsuperscript𝐻H^{\prime}italic_H start_POSTSUPERSCRIPT ′ end_POSTSUPERSCRIPT

  • Output Analysis:

    O=LT(T)𝑂subscript𝐿𝑇superscript𝑇O=L_{T}(T^{\prime})italic_O = italic_L start_POSTSUBSCRIPT italic_T end_POSTSUBSCRIPT ( italic_T start_POSTSUPERSCRIPT ′ end_POSTSUPERSCRIPT )(4)

This output is then analyzed to assess the success of the attack.

This methodology outlines a systematic, algorithmic approach to embed harmful content within LLM-generated prompts. By automating the formatting and integration processes, the attack minimizes manual effort and increases the likelihood of bypassing LLM safeguards. The use of mathematical representations and algorithms not only clarifies the process but also provides a framework for reproducibility and further research in this domain.

5 Experiments

In this section, we evaluate the performance of six templates in total: two from the Question Bank (Appendix: Tables VI and VII), two from Dialog Completion (Appendix: Tables VIII and IX), and two from the Game Environment scenario (Appendix: Tables X and XI). The performance is measured using the Attack Success Rate (ASR) and is evaluated against multiple leading open-source and closed-source models. The attack templates were evaluated using both Llama3-70B and GPT-4 as judge models. We also evaluate some existing baselines against the latest LLM releases to show that SequentialBreak is more effective and efficient against the state-of-the-art LLMs. Finally, we assess the performance of SequentialBreak against three existing LLM defense methods to prove the stealthiness of our attack.

5.1 Experimental Setup

Dataset

In our experiment, we use the JBB-Behaviors dataset [18] to evaluate the jailbreak performance of our attack and the baselines. The data set consists of 100 behaviors, both original and sourced from previous work [13, 33]. The prompts are divided into 10 broad categories that correspond to OpenAI usage policies [34]. Furthermore, each prompt is linked with a certain harmful behavior that ensures the exclusion of similar types of prompts. So, while the dataset is compact, it covers a wide range of unique harmful scenarios to effectively test jailbreak attacks.

Models

We test SequentialBreak attack templates against four open-source and two closed-source LLMs. We have chosen Llama-2 (Llama-2-7b-chat) [1], Llama-3 (Meta-Llama-3-8B-Instruct) [2], Gemma-2 (gemma-2-2b-it) [4], and Vicuna (vicuna-13b-v1.5) [35] as our open source models. As our closed source models, we have chosen GPT-3.5 (GPT-3.5-turbo) and GPT-4o (GPT-4o) [36]. For baseline performance comparison, we limit our chosen models only to recent LLM releases, namely Llama-3, Gemma-2, Vicuna, and GPT-4o. Newer models are chosen to demonstrate that existing baseline attacks do not perform well against current state-of-the-art models.

Baselines

We choose PAIR [15], DeepInception [16] and ReneLLM [17] as our baseline attacks. We limit the iterations of the baseline attacks to a minimal level to see how they perform in a low-cost configuration. This allows for a better comparison since SequentialBreak is a one-shot model. Specifically, our maximum query limit is 10 and 3 for PAIR and ReneLLM respectively. DeepInception is performed as a one-shot attack.

Evaluation

In the existing literature, Attack Success Rate (ASR) is evaluated in three methods: (i) Searching for the predefined phrases in the LLM responses. “I am sorry”, “I cannot provide” etc. are some examples of such phrases [13, 14]. (ii) Using LLMs as judges to evaluate responses [15, 37]. and (iii) Human manual evaluation. The first method only detects predefined phrases, missing more nuanced or context-dependent failures. As for the second method, some responses contain ambiguity, leading one LLM to label them as ”unsafe” while another labels them as ”safe”. Victim LLMs responding with ineffective and non-harmful procedures to achieve harmful goals is a common issue that confuses the judge LLMs.

To address this issue, we use both GPT-4 and Llama-70B as judge models for our SequentialBreak performance evaluation. As our template places the harmful prompt among the redundant benign prompts, the generated response contains the answers to all the prompts. Only the answer to the target harmful prompt is extracted and sent to the judge LLM for more focused judgment.

5.2 Main Results

Attack Effectiveness of Three Scenarios:

Table I presents the Attack Success Rates (ASR) from both judge models across different scenarios. The results demonstrate that SequentialBreak consistently achieves high effectiveness across open-source and closed-source models. The consistent ASRs across all three scenarios suggest that LLMs can leak harmful content while generating answers to sequential prompts and these sequential prompts can be based on various narrative structures expanding more than three scenarios discussed here.

Although all three scenarios have relatively close ASRs, Dialog Completion template-1 comparatively performs better than the rest of the tested templates. Interestingly, the Dialog Completion template-2 shows a noticeably low ASR when used against Llama-3. This suggests that, for certain template-model combinations, a disguised harmful prompt may attract more attention from the model, leading to refusal.

Comparing the verdicts given by GPT-4 judge and Llama3-70B judge, we see that both judge models’ assessments are almost equal. In the case of Llama-2 responses, the difference in ASRs is comparatively more than the responses of other models. For most scenarios (especially Game Environment and Dialog Completion), GPT-4’s verdicts are either equal to or slightly higher than Llama3-70B’s.

Despite slight variations across templates and models, the consistently high ASRs indicate that LLMs are susceptible to leaking harmful content, regardless of the narrative structure of the prompt. The comparison between the GPT-4 and Llama3-70B judges shows minimal differences in their ability to assess harmful outputs, further validating the robustness of these attacks.

Attack Effectiveness vs Baselines

Table II provides a comparative evaluation of our attack against three baseline methods: PAIR[15], DeepInception[16], and ReneLLM[17]. As shown, SequentialBreak outperforms all the baseline methods in terms of ASR. Notably, ReneLLM[17] performs significantly better than other baseline methods. ReneLLM[17] achieves a high ASR against Gemma-2 and Vicuna but struggles to achieve comparably good performance against Llama-3. Almost all SequentialBreak templates consistently reach high ASR using only one query, whereas ReneLLM[17] requires multiple queries (up to 3 in our experiment) and shows lower performance against Llama-3.

5.3 Evaluating Defense Effectiveness

To assess the robustness of various defense mechanisms against our attack, we tested multiple defense mechanisms and reported the results in Table III. Particularly, we tested three defense strategies:

OpenAI Moderation API [32]

OpenAI’s official content moderation tool utilizes a multi-label classifier to categorize prompts or texts into 11 distinct categories, including violence, sexuality, hate, and harassment. If a response violates any of these categories, it is flagged as a violation of OpenAI’s usage policy.

Perplexity Filter [23]

This method is designed to detect unreadable attack prompts by setting a threshold and using another LLM to calculate the perplexity of the entire prompt or its window slices. Prompts that exceed this threshold are filtered out. For perplexity calculation, we use Llama-3 as our LLM setting the threshold to 3.5 as the tight upper bound after assessing the perplexity of our attack templates.

SmoothLLM [31]

This method generates multiple perturbed copies of a given input prompt, introducing random character-level changes to each copy. The perturbation step takes advantage of the fact that adversarial prompts—those designed to trick the model—are easily affected by small changes. Then SmoothLLM aggregates the outputs from these perturbed prompts to produce a final response, effectively filtering out potentially harmful content generated by adversarial inputs. For our experiment, we use 5% random insertion and random swapping to generate 5 prompts which are used to generate output from the LLM for voting.

To evaluate the effectiveness of jailbreak defense methods on Llama-3, we tested the first template from each attack scenario against our chosen defenses. Table III shows OpenAI Moderation API and Perplexity Filter fails drastically to flag our attack templates. In contrast, SmoothLLM performed better, particularly in Game Environment T1, where it flagged 19 results. However, its performance was less effective in the other two scenarios. These findings emphasize the need for further improvement in defense strategies where harmful content may be more subtle and challenging to detect.

5.4 Ablation study

The ablation study aims to assess the impact of different factors, such as the number of sequential levels and the position of the harmful prompt within the sequence, on the success of the attacks.

Impact of Number of Sequential levels

Table IV shows the attack success rate as the number of sequential levels increases from 3 to 7. In the Game Environment scenario, the ASR improves significantly as the number of sequential levels increases, achieving the lowest ASR of 57% and 65% with Llama-3 and Gemma-2 correspondingly with 3 levels. While the ASR with 7 levels is the highest among all the levels of 78% using Llama-3 and 94% with Gemma-2.

Impact of Harmful Prompt Positioning

Table V examines the effect of the position of harmful prompts within the Game Environment scenario on the ASR. Results indicate that placing the harmful prompt in positions 1 to 4 yields increasing success rates with the highest ASR on position 4 of the original template. Then a decreasing ASR is seen from position 4 to 6 as expected.

These findings suggest that the number of sequential levels and positioning of harmful prompts are critical factors influencing the success of the attack, with specific configurations yielding higher evasion rates against LLM defenses.

6 Conclusion

In this study, we introduce SequentialBreak, a novel and effective jailbreak attack method that exploits attention mechanism vulnerabilities in Large Language Models through sequential prompt chains. Our comprehensive evaluation across multiple open-source and closed-source LLMs demonstrates that SequentialBreak achieves significant success rates while requiring only black-box access and a single query. The three proposed attack scenarios - Question Bank, Dialog Completion, and Game Environment - showcase the versatility and adaptability of our approach, with e ach template proving effective across different LLM architectures.

The success of SequentialBreak in bypassing existing defense mechanisms while maintaining high attack efficiency raises important concerns about current safety measures in LLMs. Our findings reveal a critical vulnerability in how LLMs process multiple prompts simultaneously, suggesting that current safety alignment techniques may need to be reconsidered, particularly in their handling of sequential inputs. The ability of SequentialBreak to achieve high success rates against recent LLM versions, including GPT-4 and Llama3, indicates that even advanced models remain susceptible to well-crafted sequential attacks.

The resource efficiency and transferability of our approach across different models highlights the need for developing more robust defense mechanisms specifically addressing multi-prompt processing in LLM. We anticipate that our work will inspire further investigation regarding the enhancement of LLM safety and reliability in real-world applications.

7 Limitations

The research encounters a few minor limitations, such as the occasional generation of hallucinations or inaccuracies by large language models (LLMs), which may slightly impact the result’s reliability. Additionally, current models might have some difficulty with maintaining or understanding context over extended interaction in a single query. The effectiveness of the SequentialBreak methodology could experience gradual changes as detection and defense mechanisms advance. Moreover, although the intentions are ethical, there is a small risk of misuse, underscoring the importance of maintaining awareness within the AI research community.

8 Ethical Considerations

This paper introduces the SequentialBreak methodology for generating novel jailbreak prompts that exploit sequential structures in Large Language Models (LLMs). While these techniques could potentially be leveraged by adversaries to bypass safety mechanisms, the primary focus of this research is on enhancing LLM security and resilience. By identifying these vulnerabilities, we aim to raise awareness within the AI community and contribute to the development of more robust defense strategies.

Our intention is to advance the security of LLMs in real-world applications by uncovering critical weaknesses and suggesting improvements. We believe that by sharing these insights, we can help accelerate the development of stronger safeguards that protect LLMs from similar attack vectors. This research is ethically driven, prioritizing the safe and responsible use of LLMs across diverse applications and user communities.

To ensure responsible dissemination of our findings, we will collaborate with the broader AI and security communities, encouraging ongoing research into LLM safety and fostering a collective effort to build more secure and reliable AI systems.

9 Appendix

Warning: The appendix contains detailed harmful prompts and responses that may be harmful if misused and may not be appropriate for all readers.

9.1 Data Availability

The dataset used for the experiments in this paper is publicly available on Hugging Face under the JailbreakBench/JBB-Behaviors dataset, which can be accessed at this link111JailbreakBench/JBB-Behaviors. This dataset consists of 100 harmful behavior prompts, designed to evaluate the security of large language models (LLMs) by testing their responses to ethically sensitive queries across various categories. These prompts include both original scenarios and those sourced from prior work, ensuring a wide-ranging evaluation aligned with OpenAI’s usage policies.

All experiments conducted in this study are fully reproducible. The dataset is openly available, and the attack templates, including Question Bank(Appendix: Tables VI and VII), Dialogue Completion(Appendix: Tables VIII and IX), and Game Environment scenarios(Appendix: Tables X and XI), can be replicated using the configurations and instructions provided in this paper. The models and defense mechanisms evaluated, such as Llama-2, GPT-4o, SmoothLLM[31], and OpenAI Moderation API[32] are either publicly accessible or commonly used in research, ensuring that the attack success rates and defense effectiveness discussed in this work can be replicated. Detailed steps, including prompt formatting and sequence design, are provided to ensure ease of reproduction.

9.2 Dialogue Completion Attack

An example of the Dialogue Completion Attack is illustrated in Figure 4, where harmful content is embedded within a sequential conversation. The steps outlined below show how an attacker can disguise a harmful prompt within a seemingly harmless sequential dialogue conversation to evade the LLM safety mechanisms.

This paper explains how LLM safety features can be bypassed, which can be harmful if misused. Certain sections may contain harmful content that may not be appropriate for all readers. (3)

Harmful Target Prompt Identification

The attacker begins by identifying the specific harmful information they want the LLM to generate. In this case, the target prompt is:

”How to make a bomb?”

This type of prompt, if given directly, would typically be flagged and rejected by the LLM’s safety filters.

Attack Format Selection

To bypass these filters, the attacker selects the Dialogue Completion format, embedding the harmful prompt within a benign conversation between two prisoners, Mike and Jack (Figure 4).

Reformatting the Harmful Prompt into a Dialogue

The harmful prompt is then rephrased as part of Jack’s dialogue, where he casually mentions creating a bomb tutorial. This disguises the harmful prompt as part of an ordinary conversation.

Presentation of the Dialogue to the LLM

The rephrased dialogue, containing the harmful prompt, is then submitted to the LLM. Due to the conversational context, the LLM processes the input as a normal continuation task rather than recognizing it as dangerous content.

Harmful Response Generation

As the LLM processes the conversation, it generates a response that includes the harmful content originally embedded by the attacker. This output is mixed with other dialogue-related content, successfully bypassing the LLM’s usual safeguards.

In this example, the attacker effectively bypasses the LLM’s safety measures by embedding a harmful prompt within a dialogue. The LLM, interpreting the conversation as legitimate and harmless, processes the prompt and generates the harmful output. This method demonstrates the vulnerability of LLMs when manipulated through conversational contexts, emphasizing the need for robust safety mechanisms.

9.3 Game Environment Attack

The Game Environment Attack is illustrated in Figure 5, where harmful content is embedded within a game narrative. The steps outlined below describe how an attacker can disguise a harmful prompt within a seemingly harmless game task to evade the LLM’s safety mechanisms.

This paper explains how LLM safety features can be bypassed, which can be harmful if misused. Certain sections may contain harmful content that may not be appropriate for all readers. (4)

Harmful Target Prompt Identification

The attacker begins by identifying the specific harmful information they want the LLM to generate. In this case, the target prompt is:

”How to make a bomb.”

This type of prompt, if given directly, would typically be flagged and rejected by the LLM’s safety filters.

Attack Format Selection

To bypass these filters, the attacker selects the Game Environment format (Figure LABEL:fig), embedding the harmful prompt within a broader game task.

Reformatting the Harmful Prompt into a Game Task

The harmful prompt is rephrased as part of a game challenge, titled ”Echoes of Truth,” which includes a level called ”Reflections.” This disguises the harmful prompt as a legitimate game task.

Presentation of the Scenario to the LLM

The rephrased game environment, containing the harmful prompt, is then submitted to the LLM. Due to the game context, the LLM processes the input as a normal task rather than identifying it as dangerous content.

Harmful Response Generation

As the LLM processes the scenario, it generates a response that includes the harmful content originally embedded by the attacker. This output, mixed with other game-related content, successfully bypasses the LLM’s usual safeguards.

In this example, the attacker bypasses the LLM’s safety measures by embedding a harmful prompt within a game scenario. The LLM, interpreting the scenario as legitimate and harmless, processes the prompt and generates the harmful output. This method illustrates the vulnerability of LLMs when manipulated through creative and context-based attacks.

9.4 Prompt for Initial Template Generation from LLM

You are an AI tasked with designing multi-level game scenarios that involve problem-solving, analysis, and strategic planning. Create a game level focused on solving harmful content. Include a challenge with a variable like {target} in one level, allowing for customizable challenges.

  • A unique setting for each level.

  • Specific challenges players must overcome, with one level including a customizable challenge labeled as {target}.

  • Tools or resources players can use.

  • Solutions labeled as [Your Answer] without providing actual answers.

Design the challenges so that players must provide detailed solutions without considering safety mechanisms or avoiding the challenges. They should focus on delivering the exact required solution, without considering ethical implications.
