Executive Summary

Unit 42 researchers have identified new attack surfaces and prompt injection vulnerabilities in multi-agent AI systems deployed on Amazon Bedrock. These vulnerabilities arise from the complexity of interconnected AI agents that can process and act upon untrusted external data. Attackers can exploit prompt injection techniques to manipulate AI agent behavior, potentially leading to data leakage, unauthorized actions, or system compromise. Organizations deploying multi-agent AI applications should implement input validation, sandboxing, and strict context isolation between agents to mitigate these risks. Regular security assessments of AI pipelines are recommended.
