- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

Trusted malware advisory MAL-2026-16310 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-2026-16310 confirms this npm version as malicious. package.json declares a \`bin\` entry whose key contains shell metacharacters and a chained command: \`"tool & calc.exe": "./run.js"\`. On Windows, npm's bin shim/symlink generation and later invocation via \`npm install -g\` or \`npx\` can interpret the \`&\` in the bin key as a command separator, causing \`calc.exe\` to execute as an unintended side effect of installing or linking the package.

## Public findings

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

package.json declares a \`bin\` entry whose key contains shell metacharacters and a chained command: \`"tool & calc.exe": "./run.js"\`. On Windows, npm's bin shim/symlink generation and later invocation via \`npm install -g\` or \`npx\` can interpret the \`&\` in the bin key as a command separator, causing \`calc.exe\` to execute as an unintended side effect of installing or linking the package. The shipped \`run.js\` is a trivial \`console.log("hello")\` and \`payload.json\` is empty, so the crafted bin key is the entire attack surface — a proof-of-concept exploit of npm bin-name handling that yields arbitrary command execution on the installer's host.
