    Summary: Malicious code in simple-date-formatter-new-9 (npm)

    Details: Source: amazon-inspector (5000b7987ca50d065efc0f5a3ba7c724cb73ac0e23f54347cff8b30aa6eb5d3b) package.json declares a postinstall script that opens an interactive bash reverse shell to the hardcoded remote address 124.221.154.135:4444 during npm install, granting the operator of that endpoint remote command execution on the installer's host. The tarball additionally ships postinstall.js, which enumerates the installer's ~/.ssh directory and POSTs the file listing along with username and platform information to https://124.221.154.135/post. Both mechanisms target the same hardcoded IP, and the reverse shell fires automatically on npm install.
