arXiv:2606.18530v1 Announce Type: cross Abstract: Domain-camouflaged injection attacks embed malicious instructions in retrieved content using domain-appropriate vocabulary, evading standard detectors that rely on syntactic injection markers. When detection fails, practitioners need to know which defense architectures reduce attack success. We evaluate five prompting-based defenses (spotlighting, paraphrasing, prompt sandwiching, and two combinations) against domain-camouflaged injection across three model families (Claude Haiku, Llama 3.1 8B, Gemini 2.0 Flash) and three deployment domains (fi
The proliferation of advanced large language models (LLMs) and their integration into various applications necessitates robust defense mechanisms against sophisticated new attack vectors like domain-camouflaged injection.
Understanding the effectiveness of prompting-based defenses is critical for securing AI systems, preventing misuse, and maintaining user trust in enterprise and public-facing AI deployments.
This research provides actionable insights into which defense architectures are most effective, influencing best practices for AI system developers and security practitioners.
