Outline

This paper presents a comprehensive analysis of “Prompt Injection 2.0,” an evolution of the prompt injection attack first discovered by Preamble, Inc. in May 2022 and reported to OpenAI. In particular, we analyze that the emergence of agent-like AI systems that autonomously perform multi-step tasks has led to the evolution of prompt injection attacks into a hybrid threat that systematically bypasses existing security controls by combining them with existing cybersecurity vulnerabilities (e.g., XSS, CSRF). Along with an evaluation of modern threats including AI worms, multi-agent infections, and hybrid cyber-AI attacks, we include recent benchmark results showing that existing web application firewalls, XSS filters, CSRF tokens, etc. fail against AI-enhanced attacks. We also present an architectural solution that combines prompt isolation, runtime security, privilege separation, and novel threat detection capabilities.

Takeaways, Limitations

Takeaways:
Clearly presents the severity of Prompt Injection 2.0 and the limitations of existing security systems.
Identifying a new type of threat (hybrid cyber-AI attacks) resulting from the emergence of AI agent systems.
Empirically present the effectiveness and limitations of existing security technologies.
Proposing an effective defense architecture solution against Prompt Injection 2.0.
Limitations:
Lack of detailed analysis of the actual implementation and performance of the proposed architectural solution.
Further research is needed on generalizability to various AI models and agent systems.
Continuous monitoring and response strategies are needed for new prompt injection attack variants.
