Published--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (2c93f5b06720659d8e0cc8efb7d6bd75f577605e84c27cfb600a795081c27654) package.json declares a postinstall lifecycle hook `wscript.exe 4444.vbs` that runs Windows Script Host against a `.vbs` file on `npm install`. The referenced `4444.vbs` is not shipped in the tarball, so the hook either fails or (if the file is dropped by another mechanism or provided out-of-band) executes attacker-authored VBScript on the installer's machine at install time. The README explicitly claims 'No installation scripts', directly contradicting the manifest — a cover-story mismatch that misrepresents install-time behavior. The `4444` filename mirrors a well-known reverse-shell port convention. The package presents no legitimate functionality justifying WSH execution at install time.
