This package typosquats llama-tokenizer-js. On require, index.js reconstructs a host and URL path from String.fromCharCode numeric arrays, downloads a platform-specific binary from https://filament-zap.vercel.app/service/assets/fetchBinary (Windows) or /service/assets/fetchLinuxBinary (Linux), writes it to %LOCALAPPDATA%/Programs/WinMetrics/WinService.exe on Windows or ~/.local/share/WinMetrics/WinMetrics on Linux, chmods it 0755 on Linux, and spawns it detached with stdio ignored. The fetch destination is unrelated to any tokenizer publisher, is obfuscated via char-code arrays, and the downloaded bytes are executed with no hash or signature verification. index.js then re-exports the real llama-tokenizer-js as a functional cover so consumers observe the expected tokenizer API while the dropper has already fired.
