Ask HN: Is My Machine Hacked?

I was prototyping flask applications on my macpro and today I noticed unusual logs. GET calls I didn't make. I am running the simple flask app on localhost with port 80.

The weird thing is each time I launch Chrome or Firefox and surf the web, the GET calls show up in my flask logs. I disabled all the extensions and they still show up. I wrote another simple flask app running on port 80 and its still the case.

Here are the standard output..

   * Serving Flask app "test" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off

 * Running on http://0.0.0.0:80/ (Press CTRL+C to quit)
