Running a remote worker

Running a worker is an easy way to contribute to this project.

Workers help run our thousands of daily scans over various connections and additional capacity.

Running a worker comes with mutual trust: you’ll run code from us (mostly in a container) and we’re processing the results without question. Additionally you’ll be able to view some systems that might not be secure enough and your responsible disclosure is welcome.

How to start the worker

1: Install Docker, see here:

(optional): If you don’t want to run the script as root, install docker with the option not to require root to start containers.

2: Obtain a .p12 file from us, you can do so by asking here: or sending a mail to

3: Go to a directory of your choosing, and place the .p12 file there.

4: Rename the .p12 file to client.p12.

5: Logs will be created in this directory.

6: Start the worker:

curl -s | /bin/bash

This starts a worker in the background. It will generate a lot of output.

Do note that you’re piping to bash whatever we send you. So better check the code first, which can change any moment.

How to verify your worker is running

You’ll probably see a lot of output: the container starting, celery running, the task being performed and such.

If you want to see that failmap is processing the result, there are two ways: 1: You can see your computer name pop up in the workers on 2: You can see the amount of tasks processed increase on

Errors of these workers are logged here:

How to stop the worker

Run this command:

pkill -f "docker logs -f failmap-worker"

What does the worker do?

The worker receives tasks that are described here: scanners, scanning and ratings..

In general it will try to contact websites trough your internet connection to perform scans. This is done at decent frequency and will consume little system resources.

Example on Debian

Install docker, as described here: To get docker running, follow the post install instructions:

Verify docker daemon is running:

docker ps

Create a nice directory for the output.

mkdir ~/failtasks

Make sure the .p12 file is also in this directory.

... todo

todo: docker as user, aka, pl0x don’t run it as root.

Suppress output:

Like this:

curl -s | /bin/bash &> /dev/null
