The section also includes trends, product material, and actor naming updates. An earlier title review on September 10, 2026 estimated that about 13-15% covered guidance or similar topics and about one third covered criminal activity. Those estimates were based on titles; criminal activity with a multistep attack chain may still qualify for this dataset.",
