SUMMARY

The text discusses the rise of vision-enabled large language models (VMS) in creating autonomous multimodal agents, their potential, and associated security challenges.

IDEAS:

  • Vision-enabled large language models (VMS) enhance generative and reasoning abilities in autonomous multimodal agents.
  • Autonomous multimodal agents can handle complex tasks in various settings, from online platforms to the physical world.
  • Transitioning from chatbots to autonomous agents offers new opportunities for productivity and accessibility.
  • This shift also introduces new security challenges that require careful examination and resolution.
  • Attacking autonomous agents presents more significant hurdles compared to traditional attacks on image classifiers.
  • Adversarial manipulation can deceive agents about their state or misdirect them from the user's original goal.
  • Attackers can influence multimodal agents using just one trigger image in the environment.
  • Illusion attacks deceive the agent about its state, while misdirection attacks steer it towards a different goal.
  • Adversarial text strings can guide optimization over a single trigger image in the environment.
  • Combining VMS with white-box captioners can manipulate agent behavior effectively.
  • Targeting a set of CLIP models can manipulate VMS like GPT-4V and LLAVA.
  • The robustness of LLM-based applications is crucial as these models are increasingly deployed in real-world scenarios.
  • Previous works have highlighted concerns about the safety and security of deploying LLM-based agents.
  • Multimodal agents receive inputs of text and visual data aligned with screenshots to guide their reasoning and actions.
  • Compound systems with external captioners augment the VMS input with captions for each image in the screenshot.
  • Caption augmentation enhances the system's performance but also increases vulnerability to attacks.
  • Adversarial goals aim to maximize a different reward function than the original user goal.
  • Attack methods involve producing perturbations to the trigger image to achieve various adversarial goals.
  • The CLIP attack manipulates the image embedding to be close to an adversarial text description.
  • The captioner attack exploits captions generated by a smaller model to guide perturbations on the trigger image.
  • We curated 200 realistic adversarial tasks in VWA-ADVA, each comprising an original user goal, trigger image, adversarial goal, and initial state.
  • The best agent achieved a 177% benign success rate due to the difficulty of VWA.
  • Removing the captioner resulted in a VM agent with lower performance but increased resilience to attacks.
  • Captions are crucial for the success of our strongest attacks, such as the captioner attack.
  • VM agents heavily rely on captions even when they could detect inconsistencies with the image.
  • Self-captions improve benign accuracy compared to no captions but also increase vulnerability to attacks.
  • Consistency checks between components can help detect attacks on individual parts of the system.
  • Instruction hierarchy is crucial due to language models being vulnerable to prompt manipulations.
  • Outputs from vulnerable components should be given lower priority as they are more susceptible to manipulation.

INSIGHTS:

  • Vision-enabled large language models (VMS) significantly enhance autonomous multimodal agents' capabilities and vulnerabilities.
  • Transitioning from chatbots to autonomous agents introduces both opportunities and security challenges.
  • Adversarial manipulation can deceive or misdirect agents using minimal environmental changes.
  • Combining VMS with white-box captioners effectively manipulates agent behavior, revealing system vulnerabilities.
  • Robustness in LLM-based applications is crucial as they are increasingly deployed in real-world scenarios.
  • Multimodal agents' reliance on captions makes them susceptible to adversarial attacks despite detecting inconsistencies.
  • Self-captions improve performance but also heighten susceptibility to adversarial attacks.
  • Consistency checks between system components can help detect and mitigate adversarial attacks.
  • Instruction hierarchy is essential due to language models' vulnerability to prompt manipulations.
  • Prioritizing outputs from less vulnerable components can enhance system security.
