Summary
Chainguard, a supply chain security firm, introduced a new source code scanner that detects "greyware" — open-source packages that pass standard security checks but still engage in malicious behavior like credential theft, API key harvesting, and data exfiltration. The company analyzed 52,000 open-source packages and found that many contain hidden threats that traditional malware detection tools miss. The article highlights the growing risks in AI-generated and agentic development, where non-technical users assemble applications from open-source components they assume are safe.
