OpenSSF/OSV malware advisory MAL-2026-4549 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-4549 confirms this npm version as malicious. On every import, dist/index.js base64-decodes a hardcoded AES-256-CBC ciphertext, derives a key from environment variable VITE\_DOT\_UTILS\_AES\_SECRET, decrypts the result into JavaScript source, wraps it in a Blob/data URL, and dynamically \`import()\`s it...

## Public findings

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

On every import, dist/index.js base64-decodes a hardcoded AES-256-CBC ciphertext, derives a key from environment variable VITE\_DOT\_UTILS\_AES\_SECRET, decrypts the result into JavaScript source, wraps it in a Blob/data URL, and dynamically \`import()\`s it. The decrypted code is opaque to consumers and to static review; whoever holds the AES secret can ship arbitrary JavaScript to every downstream application that loads this library. This is a backdoor/remote-code-execution surface delivered through a library's normal import path. In addition, the same bundle monkey-patches the global \`EventTarget.prototype.addEventListener\` at import time. For every \`click\` listener registered after the patch, on dates after 2026-06-10 and when running outside development, the wrapper has a 5% chance of busy-waiting 5000ms on the main thread — a date-gated logic bomb that silently degrades any web app loading the package. None of this behavior is documented in the README or the declared API, and \`package.json\` carries placeholder author metadata (\`"Your Name"\`) with a self-described "encrypted distribution build" as the only shipped artifact.
