Fighting AI with AI: AI-Agent Augmented DNS Blocking of LLM Services during Student Evaluations

Researchers introduce AI-Sinkhole, an AI-agent augmented DNS-blocking framework that dynamically detects and temporarily blocks LLM chatbot services during proctored exams to prevent academic integrity violations. The system uses quantized LLMs for semantic classification and Pi-Hole for network-wide DNS blocking, achieving robust cross-lingual detection with F1-scores exceeding 0.83.
