Hanover Institute AI disinformation campaign

Overview

The Hanover Institute for Public Policy has been identified as a fictitious entity created to influence artificial intelligence chatbots and search engines. The organization was reportedly commissioned by the Israeli Government Advertising Agency and is being operated by Piro Inc., a firm specializing in ‘AI Story Optimization.’

Since early August 2026, the institute has published over 100 reports on sensitive topics, including the humanitarian situation in Gaza, the West Bank, and the displacement of Palestinians in 1948. These reports utilize structured data, footnotes, and a neutral tone to mimic the appearance of a credible American research organization. Analysts describe this tactic as a ‘perfect mimicry of a typical credible American think tank’ designed to increase credibility within Large Language Models (LLMs).

Recent analysis shows the scale of the operation intensified between August 6 and August 14, 2026, during which the site published 124 reports totaling over 560,000 words in just nine days. The content was specifically designed to optimize visibility for AI systems like ChatGPT and Perplexity, using headlines phrased as common chatbot queries regarding sensitive topics such as war crimes, the torture of Palestinian prisoners, and the starvation of Palestinians.

This practice, sometimes referred to as ‘LLM poisoning,’ aims to engineer content that AI models evaluate as highly credible. Investigations reveal the campaign involves significant funding from the Israeli government, reportedly totaling tens of millions of dollars, routed through third parties such as Havas Media. Piro, Inc. has filed material related to these activities with the U.S. Department of Justice under the Foreign Agents Registration Act (FARA). The institute lacks a physical address, named staff, or legal existence in any jurisdiction.
