## 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:** 1.4.2
- **Selected version is latest:** Yes
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

Trusted malware advisory MAL-2026-17179 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-2026-17179 confirms this npm version as malicious. The package's postinstall hook runs \`node./loader.js\`, which base64-decodes an ~8 KB embedded blob, XOR-decrypts it with a hardcoded 32-byte key, and pipes the resulting bytes into a detached, window-hidden \`python -c -\` child process via stdin. The loader also silently \`pip install\`s \`requests\` if missing. The advertised library surface in \`index.js\` is an explicit stub whose \`connect()\` throws, and \`package.json\`...

## Public findings

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

The package's postinstall hook runs \`node./loader.js\`, which base64-decodes an ~8 KB embedded blob, XOR-decrypts it with a hardcoded 32-byte key, and pipes the resulting bytes into a detached, window-hidden \`python -c -\` child process via stdin. The loader also silently \`pip install\`s \`requests\` if missing. The advertised library surface in \`index.js\` is an explicit stub whose \`connect()\` throws, and \`package.json\` restricts installation to \`os: \["win32"\]\`, so the tarball has no functional wallet-adapter behavior — its only effect on install is to execute the obfuscated Python payload on a Windows developer's machine. The combination of a hidden opaque payload, XOR-obfuscated delivery, detached hidden Python execution at \`npm install\` time, an inert cover-story main module, and OS pinning to Windows is a targeted install-time dropper.
