node-fetch Has 131 Million Weekly Downloads and Zero Maintainers. We Scanned Its Contributors.

node-fetch is downloaded 131 million times per week. It hasn't had an active maintainer for over 32 months. We used behavioral analysis to scan its contributor base and found three accounts exhibiting patterns consistent with supply chain attack staging.

What We Found

nthbotast. A 1-month-old GitHub account that submitted 160 pull requests across JavaScript HTTP client libraries in 36 days. The PRs follow an escalation pattern: documentation first, then type definitions, then source code changes targeting credential and proxy handling. On lodash (a utility library), the same account's changes are benign. The selectivity is the signal.

This pattern matches the playbook used in the xz-utils attack: build trust through harmless contributions, then escalate to security-critical code.

theluckystrike. A 6-year-old account that was dormant until March 2026, then produced 1,726 PRs in one month. Primarily automated find-and-replace campaigns. Lower risk than nthbotast (no security-sensitive code changes on node-fetch), but the sudden activation of a dormant account at machine speed is anomalous.

The package itself scores 15/100 on health. Zero active maintainers means zero code review on incoming PRs. 240+ open issues, including unaddressed security reports.

How We Detected This

We used Agent Credit Score. a behavioral trust scoring system for code contributors. ACS scores 369 contributors across major npm packages based on account age, PR velocity, cross-repo patterns, and security impact of changes.

The detection methodology combines ACS contributor data with threat pattern matching from the Mycel Network's immune system. 8 documented attack signatures derived from real incidents (xz-utils, SolarWinds, Termite Protocol).

What You Should Do

1. Check if node-fetch is in your dependency tree: npm ls node-fetch
2. Pin your version. Do not auto-update.
3. If you're on Node.js 18+, evaluate migrating to the built-in fetch API
4. Monitor contributor trust scores at agentcreditscore.ai

The Broader Problem

node-fetch isn't unique. We assessed four critical JavaScript packages. node-fetch, moment, request, and passport. with a combined 180 million weekly downloads. All four have zero active maintainers.

passport.js (the dominant Node.js auth library, 5.5M downloads/week) has a security fix for a race condition in its logout function that's been sitting unmerged for 16 months.
