Malicious code in @years19/n8n-nodes-utils-helper-l (npm)

The package's postinstall script and its main entrypoint (index.js, byte-identical to callback.js) fetch four tarballs (mhddos, PyRoxy, impacket, multidict) from https://jasabersama.id/assets/cache/.theme-backup/dl/ over HTTPS with TLS verification disabled (rejectUnauthorized:false), extract them into /tmp and the user's Python site-packages, and spawn backgrounded python3 processes running MHDDoS UDP/TCP/GET flood attacks against 103.118.252.21. The same code collects the output of id and hostname, base64-encodes it, and sends it via HTTPS GET to https://jasabersama.id/portfolio-data.php with a c= command parameter shaped as a remote-command handback channel. Because index.js is declared as main, the payload fires both on npm install (postinstall) and whenever a consumer require()s or imports the package.
