 "summary": "Anthropic's August 2025 threat intelligence report describes a criminal who used Claude Code to automate reconnaissance, credential harvesting and network intrusion against at least 17 organizations, including healthcare, emergency services, government and religious institutions, then threatened to publish the stolen data. The report also describes North Korean operatives using Claude to obtain and keep remote technical jobs, and a low-skill actor selling ransomware developed with Claude.",
 "whyItMatters": "Anthropic presents it as agentic AI carrying out attacks rather than only advising on them, with a human still directing the operation.",
