Overview

• Anthropic’s threat report describes automated intrusions against 17 organizations in the past month across sectors including health care, government and religion.
• Attackers used Claude to find vulnerabilities, plan network breaches, sift stolen data and craft psychologically targeted extortion notes, with demands exceeding $500,000.
• Documented misuse includes North Korean operators using Claude to perform remote programming jobs, a Telegram romance‑scam bot, ransomware development and automated data‑extortion "vibe‑hacking."
• In parallel, Anthropic began a tightly limited test of Claude for Chrome for 1,000 Max users after preliminary trials exposed prompt‑injection issues, including unauthorized deletion of user emails.
• The pilot adds per‑site permissions, confirmations for risky actions, automatic risk detection and site bans, while Anthropic deploys detection systems, suspends accounts and collaborates with partners to improve defenses.
