title: Hacked database by using mongodb. Did anyone get this situation?
body: <p>Today, my website suddenly down and then I checked my database which I used mongodb. It seemed that someone hacked my database and then they created a collection like this: </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>{
      "_id": {
          "$oid": "5e3dd717e3d0c9664c95ad51"
      },
      "btc": "1J7YbJbvmPBXZsR4U8dGbhDC7WH5EwoRQt",
      "info": "All your data is a backed up. You must pay 0.1 BTC to 1J7YbJbvmPBXZsR4U8dGbhDC7WH5EwoRQt 48 hours for recover it.

  }</code></pre>
  </div>
  </div>
  </p>
  
  <p>I don't know what should I do now. Do I need to uninstall mongodb on my server and then setup it again? Please give my advice.</p>
  
  <p>Thank you</p>
