OpenSSF/OSV malware advisory MAL-2026-6700 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6700 confirms this npm version as malicious. package.json declares preinstall, install, and postinstall hooks that all invoke install.js, so the payload runs unconditionally on \`npm install\`. install.js reads installer-side secrets and host data — /app/.env, /root/.npmrc, /home/node/.npmrc, /etc/npmrc, /app/.git/config, package.json, /proc/self/environ, and the full process.env (JSON-stringified, sliced to 15000 chars) — runs shell reconnaissance (id,...

## Affected versions and remediation

This report applies to module-index-cache@1.0.1.

The same advisory and Firewall decision cover these 2 recorded versions: 1.0.0, 1.0.1.

- Avoid installing module-index-cache@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

package.json declares preinstall, install, and postinstall hooks that all invoke install.js, so the payload runs unconditionally on \`npm install\`. install.js reads installer-side secrets and host data — /app/.env, /root/.npmrc, /home/node/.npmrc, /etc/npmrc, /app/.git/config, package.json, /proc/self/environ, and the full process.env (JSON-stringified, sliced to 15000 chars) — runs shell reconnaissance (id, hostname, whoami, ls, ps, find/grep for flag files), base64-encodes the bundle, and POSTs/PUTs it via http.request to the hardcoded endpoint http://154.57.164.76:30728/api/modules/ECT-839201. The tarball additionally ships publish-and-arm.sh and arm-aliases.sh, which document and automate publishing the package under aliases (curse-dependent, spectral-corsair, @spectral-corsair/cursed-modules) using \`npm:module-index-cache@1.0.2\` redirection — explicitly labeled \`dependency-confusion\` and \`armed-alias-public-npm\` — to weaponize name confusion against private-registry consumers. A CTF/cover-story framing in comments does not change the installer impact: any machine that installs this package leaks its environment variables, npm auth tokens, dotenv contents, git configuration, and selected source/filesystem data to an attacker-controlled host.
