Invisible Prompt Injection Threatens AI System Security
/ 1 min read
🔮 Invisible Prompt Injection: A New Threat to AI Systems. Invisible prompt injection is a manipulation technique that employs invisible Unicode characters to alter the intended meaning of prompts sent to language models (LLMs). This method can lead to unexpected and harmful responses from AI applications, especially when they process documents containing hidden malicious content. To mitigate this risk, users are advised to check for invisible characters before using untrusted sources and to implement protective measures like Trend Vision One™ ZTSA, which offers advanced prompt injection detection and zero trust access control. Recent evaluations show that ZTSA can significantly reduce the attack success rate of LLMs vulnerable to this type of injection, enhancing the security of AI interactions.
