Anthropic Security Breach: Claude Code Source Exposed via npm Registry (heise.de)

• Full source code of Claude Code leaked via npm source map.
• Human error in the deployment process of proprietary software to public registries.
• Increased risk of reverse engineering and vulnerability discovery in AI tooling.

"A configuration error during publication on the npm registry inadvertently exposed the full source code of Anthropic’s new CLI tool, 'Claude Code.' The inclusion of a source map allowed external parties to reconstruct the proprietary code. This incident highlights critical vulnerabilities in the modern software supply chain and demonstrates how even leading AI firms can succumb to basic DevOps missteps, impacting digital sovereignty and intellectual property protection."
