AutoDAN-Turbo: A Black-Box Jailbreak Method for LLMs with a Lifelong Agent

Understanding the Challenges of Large Language Models (LLMs)

Large language models (LLMs) are popular for their ability to understand and generate text. However, keeping them safe and responsible is a major challenge.

The Threat of Jailbreak Attacks

Jailbreak attacks are a key concern. These attacks use clever prompts to make LLMs reveal harmful or inappropriate content. To ensure LLMs behave responsibly, we need to explore automatic jailbreak attacks as essential tools for testing safety.

Types of Jailbreak Attacks

There are two main types of jailbreak attacks:

Optimization-based attacks: These use algorithms to create prompts based on feedback. However, they often lack diverse prompts, leading to weaker attacks.
Strategy-based attacks: These use specific strategies, like role-playing or wordplay, to exploit weaknesses in LLMs. While they show vulnerabilities, they rely too much on human-designed strategies and don’t explore combinations of different methods.

Introducing AutoDAN-Turbo

Researchers have developed AutoDAN-Turbo, a method that uses lifelong learning agents to automatically find and combine diverse strategies for jailbreak attacks. This innovation offers several advantages:

Automatic Strategy Discovery: It can create new strategies on its own and store them for future use.
External Strategy Compatibility: It allows easy integration of existing strategies, enhancing flexibility.
Black-Box Operation: It only needs access to the model’s text output, making it practical for real-world use.

How AutoDAN-Turbo Works

AutoDAN-Turbo consists of three main components:

Attack Generation and Exploration Module: Generates prompts targeting a victim LLM, evaluated by a scoring LLM.
Strategy Library Construction Module: Collects and organizes strategies from attack logs.
Jailbreak Strategy Retrieval Module: Retrieves strategies from the library for future attacks.

This process allows continuous development and evolution of jailbreak strategies. Importantly, it requires only text output, making it applicable without direct access to the model.

Performance and Effectiveness

AutoDAN-Turbo outperforms existing methods significantly in tests:

Achieves an average Harmbench ASR of 56.4, exceeding the runner-up by 70.4%.
Shows remarkable results against GPT-4, with ASRs of up to 88.5.

Its strength lies in autonomous strategy exploration, unlike methods that depend on limited human-developed strategies.

Conclusion and Next Steps

AutoDAN-Turbo represents a major step forward in jailbreak attack methods, using automated agents to find and combine strategies. While it does require significant computational resources, using a pre-trained strategy library could enhance efficiency.
