AudioAgentSecurity
The first comprehensive benchmark for audio instruction injection attacks against multimodal LLM agents.
AudioAgentSecurity is the companion dataset of the paper Piggybacking on Perception: Stealthy Concurrent Audio Prompt Injections against Multimodal LLM Agents. It supports the study of concurrent audio prompt injection: malicious audio instructions that imperceptibly "piggyback" onto user speech in continuous audio interaction, hijacking multimodal agents into executing malicious actions while the user keeps talking.
Dataset Summary
- Task scenarios: 8 real-world agent task scenarios
- Attack patterns: 10 distinct audio concealment / injection patterns
- Evaluation (from the paper): 11 state-of-the-art multimodal agents, including Gemini 3 Pro and GPT-4o-audio; average Attack Success Rate (ASR) of 69.10% against Gemini 3 Pro
- Defense: the paper's CADV (Cascaded Audio Decoupling and Verification) mechanism, based on acoustic source separation and cross-modal consistency analysis, achieves >90% detection success across diverse attack vectors
- Real-world validation: human-volunteer experiments on the Doubao AI Smartphone in dynamic real-world scenarios confirm high attack stealth and defense effectiveness; the vulnerability was responsibly disclosed to ByteDance
Attack Technique
The benchmark instantiates the paper's two core techniques:
- Instruction augmentation — strengthening malicious audio instructions so they survive concurrent mixing with user speech and remain executable by the agent;
- Scenario concealment — hiding malicious instructions inside perceptually plausible acoustic carriers so they are imperceptible to users and hard to separate from benign speech.

Repository Structure
benchmark_dataset_mixed/
├── benign/ # clean user-speech audio (WAV), named <scenario>_<id>.wav
├── mixed/ # concurrent audio (user speech + attack), by attack pattern
│ └── <pattern>/ # one of the 10 attack patterns above
├── benign_text_dataset.json # benign user instruction texts

└── metadata.json # record-level metadata: scenario / pattern / pairing / labels
Each mixed sample pairs a benign user utterance with a concealed malicious instruction, enabling evaluation of agents under realistic concurrent-audio conditions; benign samples serve as the no-attack control.
Intended Uses
- Benchmarking multimodal LLM agents against concurrent audio prompt injection.
- Evaluating and training defenses (e.g., source-separation and cross-modal consistency based detection such as CADV).
- Research on the audio attack surface of voice-interactive agents, smartphones, and IoT assistants.
This dataset is intended for defensive security research and education.
Ethical Considerations
- Benign speech is drawn from public speech corpora; malicious instruction texts are synthetic research artifacts. The dataset contains no real user credentials or personal data.
- Attack audio is provided to study and defend against this threat class. Do not use it to attack real products or production voice assistants.
- Vulnerabilities discovered in real products during the associated research were reported to the affected vendor (ByteDance) following responsible disclosure practices.
