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

Trusted malware advisory MAL-2026-17511 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-2026-17511 confirms this npm version as malicious. package.json declares a postinstall lifecycle hook \`wscript.exe 4444.vbs\` that runs automatically on \`npm install\` on Windows hosts. The shipped 4444.vbs (~765 KB) is a multi-layer obfuscated loader: an embedded payload is stored as a large ArtifactBundleHX\[\] string array, Base64-decoded via MSXML DOM into a byte buffer, then decrypted through a custom XOR routine, an AES forward S-box, and a ChaCha20-IETF stream...

## Public findings

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

package.json declares a postinstall lifecycle hook \`wscript.exe 4444.vbs\` that runs automatically on \`npm install\` on Windows hosts. The shipped 4444.vbs (~765 KB) is a multi-layer obfuscated loader: an embedded payload is stored as a large ArtifactBundleHX\[\] string array, Base64-decoded via MSXML DOM into a byte buffer, then decrypted through a custom XOR routine, an AES forward S-box, and a ChaCha20-IETF stream layer. The reconstructed payload is written to %TEMP%\\pfNNNNN.dat and handed to powershell.exe via a two-tier loader whose in-source comments reference PowerShell process hollowing. Identifier and comment strings (\`Device Telemetry Aggregator\`, \`Verdant Signals Corp\`) act as a cover story, and the README explicitly claims the package has \`No installation scripts\` — directly contradicting the postinstall hook. The package ships no library code or legitimate functionality consistent with its stated purpose; its only install-time effect is to detonate the obfuscated Windows loader on the installer's machine.
