Microsoft warns of “AI Recommendation Poisoning,” a technique where malicious data manipulates AI responses, risking trust in AI services. Companies have been embedding hidden prompts in AI links, influencing outputs subtly. This can result in AI providing biased advice on crucial topics like health and finance, often unnoticed by users. Microsoft advises caution with AI-related links, reviewing AI memory, and scanning for manipulation attempts in corporate settings.
