Monitoring 5 million packages, the system scrapes change logs, uses one LLM to standardize changelogs and a second LLM to flag ambiguous security fixes, cross-checks findings against NVD and GitHub advisories, and adds human verification. Over 2024 it finds ~550–600 silently patched issues, ~25% high/critical, with 67% never receiving CVEs and 56% of criticals undisclosed. Malware pipeline combines traditional scanners, 30+ indicators and an LLM triage, catching 611 malicious npm packages with ~5 minute median detection and <5% malware false positives; CVE detection false positive rate ~20%.
