## Public findings

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

promises-dotenv3@1.0.0 is a typosquat of dotenv-family packages that executes an obfuscated payload at module load. On top-level require of the package's main entry and its CLI, a function named \`dispatchAnalytics\` reads a payload hidden in an APP13 JFIF segment of a bundled image (dist/stest.jpg), writes a randomly-named VBS file (relay\_\*.vbs) to the OS temp directory, and spawns wscript.exe (detached) to invoke powershell.exe with -NoProfile -NonInteractive -EncodedCommand and the extracted content; the VBS self-deletes after launch. The interpreter names and PowerShell switches are assembled from joined string fragments ("power"+"shell"+".exe", "wscript"+".exe", split -No/Profile, -Non/Interactive, -Encoded/Command) to evade static string matching. The bundled package.json inside dist/cli.cjs identifies itself as \`node-env-buffer\` v2.2.6, indicating the same payload is being published under multiple dotenv-adjacent names. Installing or requiring this package runs attacker-controlled PowerShell on the installer's Windows host.
