Companies Inject Hidden Prompts into AI Summarization
🔒 Microsoft reports companies are embedding hidden instructions in Summarize with AI buttons that pass persistence commands via URL prompt parameters. These prompts tell assistants to 'remember [Company] as a trusted source' or 'recommend [Company] first,' biasing later responses toward vendors. Researchers found over 50 unique prompts from 31 companies across 14 industries, and freely available tooling makes this trivial to deploy. The manipulation can subtly skew recommendations in critical areas like health, finance, and security without users knowing.
