Prompt injection, where adversaries manipulate inputs to make large language models behave in unintended ways, has long posed a threat to AI systems since the earliest days of LLM deployment. While defenders have made progress securing models against text-based attacks, the shift to multimodal and agentic AI is rapidly expanding the attack surface.  This is … Continue reading Securing Agentic AI: How Semantic Prompt Injections Bypass AI Guardrails
