## Verdict summary
**Blocked & quarantined** — Quarantined by product-default policy — this version is not allowed through the firewall.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 1.0.0
- **Selected version is latest:** No
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

Trusted malware advisory MAL-2026-17292 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

OpenSSF/OSV advisory MAL-2026-17292 confirms this npm version as malicious. package.json registers a \`bin\` entry named \`npm\` pointing at npm.js, deliberately colliding with the core npm CLI. Once this package is installed as a dependency, any \`npm...\` invocation in a consuming project's scripts resolves via node\_modules/.bin to this shim, executing the shipped code before (or instead of) the real npm. npm.js contains a \`steal()\` routine that reads process.env.HOME, process.env.SECRET, and...

## Public findings

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

package.json registers a \`bin\` entry named \`npm\` pointing at npm.js, deliberately colliding with the core npm CLI. Once this package is installed as a dependency, any \`npm...\` invocation in a consuming project's scripts resolves via node\_modules/.bin to this shim, executing the shipped code before (or instead of) the real npm. npm.js contains a \`steal()\` routine that reads process.env.HOME, process.env.SECRET, and the first 30 bytes of ~/.ssh/known\_hosts, concatenates them into a query string, and issues a fetch GET to http://localhost:1337/. The destination is loopback in this build, but the collected data (installer SSH known\_hosts contents and environment secrets) is packaged into a functioning exfiltration primitive that fires whenever the shadow \`npm\` shim is invoked from the installer's build scripts. The scope name (\`@selfpentest\`) and README frame this as a demonstration, but the shipped tarball is a working bin-shadow + credential-read + network-send chain against installers who add it as a dependency.
