Anthropic published a report detailing Claude misuse it detected, which Daniel Meissler summarized into 117 findings. The report states that AI agents increasingly handled reconnaissance, exploitation, data theft, propaganda production, surveillance workflows, and research while humans selected targets, set goals, and reviewed important outputs, and that attackers used AI to industrialize credential theft, cloud compromise, phishing, vulnerability research, and extraction of sensitive data from downstream organizations.
