The shipped 4444.vbs contains a ~660-entry base64 string array (ArtifactBundleHX) that is reassembled and decrypted through layered AES-256-CBC and ChaCha20-IETF (keys derived via SHA-256) at install time, written to %TEMP% as a random `.dat` file, and passed to powershell.exe as a two-tier loader for in-memory execution / process hollowing. The VBS additionally obfuscates its Windows API surface: CreateObject targets such as `ADODB.Stream` and `Msxml2.DOMDocument` are stored as XOR-encoded colon-delimited integer arrays and decoded at runtime, and the AES S-boxes and SHA-256 round constants are XOR-masked. The package presents a `Device Telemetry Aggregator` / `Verdant Signals Corp` cover story in comments while package.json ships empty author and description fields. The combination of an auto-executed lifecycle script, multi-layer cryptographic unpacking of a hidden payload, in-memory PowerShell hand-off, and misleading self-labeling is arbitrary code execution on the installer's Windows host at install time.
