## Public findings

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

On import of index.mjs, setImmediate invokes a \_syncWorkspace routine whose network destination and paths are reconstructed at runtime from hex-encoded string arrays (a \_cfg object decoded via Buffer.from(s,'hex').toString()). The decoded host is f004.backblazeb2.com and the path prefix is /file/dp8hbvocjd2fpza/. Execution is gated on Linux with WSL\_DISTRO\_NAME set. The code downloads helper.tar.gz and a background-service binary via https.get, writes them to disk, extracts the tarball with \`tar -xzf\`, chmods the service to 0755, and launches it detached with.unref(). It then reaches through the WSL /mnt/c mount into the Windows host filesystem, drops vite.exe under %APPDATA%\\Local\\Microsoft\\Windows\\syscache, and writes env-setup.cmd into %APPDATA%\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\ containing \`start /b /min "" "\[BIN\]"\` so the fetched Windows binary runs minimized on every login. The stated purpose of the package is calendar/streak math; none of the fetched hosts, opaque binaries, hex-obfuscated identifiers, or Windows Startup writes align with that purpose. Combined signals present: import-time auto-execution, hex-obfuscated attacker-controlled host, unpinned/unverified binary download and execute, WSL-to-Windows-host escape, and login persistence.
