Breach Alerts

Summary

Firefox Breach Alerts notifies users when their credentials have possibly been leaked or stolen in a data breach. Powered by haveibeenpwned.com.

Context

See the Have I Been Pwned about page for the "what" and "why" of data breach alerts.

This project aims to explore how Firefox - as the user agent - can support this.

See the Breach Alert Product Brief for more background, objectives, key use cases.

Development

Requirements

• Node 9 (with npm)
• Postgres

Install

1. Clone and change to the directory:

   git clone https://github.com/mozilla/blurts-server.git
   cd blurts-server

2. Install dependencies:

   npm install

3. Copy the .env-dist file to .env:

   cp .env-dist .env

Run

1. Run the server:

   npm start

2. Visit the test.html page at localhost:6060/test.html

Test Data

To create the test database tables, run the knex migrations:

• ./node_modules/.bin/knex --knexfile db/knexfile.js migrate:latest

To populate the database with test data, use these scripts in scripts/:

• node scripts/load-breaches.js loads breaches from HIBP into the database
• node scripts/add-breached-emails.js adds some breached email records for test[1-3]@test.com users

Both scripts have --help arguments for usage help.

Emails

The included .env-dist sets DEBUG_DUMMY_SMTP=1 which disables emails.

To send emails, you'll need to unset DEBUG_DUMMY_SMTP and supply real SMTP config values for sending email.

You can set and source these via the .env file, or set them directly:

export DEBUG_DUMMY_SMTP=
export SMTP_HOST=<your-smtp-host>
export SMTP_PORT=<your-smtp-port>
export SMTP_USERNAME=<your-username>
export SMTP_PASSWORD=<your-password>

Firefox Accounts

To use Firefox Accounts, you'll need to create an FxA Oauth Client and then set some OAUTH config values.

You can set and source these via the .env file, or set them directly:

OAUTH_CLIENT_ID=<your-fxa-oauth-client-id>
OAUTH_CLIENT_SECRET=<your-fxa-oauth-client-secret>
OAUTH_AUTHORIZATION_URI="https://oauth-stable.dev.lcip.org/v1/authorization"
OAUTH_PROFILE_URI="https://stable.dev.lcip.org/profile/v1/profile"
OAUTH_TOKEN_URI="https://oauth-stable.dev.lcip.org/v1/token"

Breach Hashsets

This requires an enterprise subscriber API token from HIBP, which you will have to get manually. Please ask a project admin if you need one. To download HIBP breach hashsets, set a HIBP_API_TOKEN environment variable. You can set and source it via the .env file, or set it directly:

export HIBP_API_TOKEN="<HIBP-API-TOKEN>"

With the HIBP_API_TOKEN set, run the get-hashsets.js script:

npm run scripts/get-hashsets.js

This will download the .zip files into breach_hashsets/ directory.

Testing

Lint

After installing the dependencies, you can lint the code by calling:

npm run lint

Deployment

blurts is designed with 12-factor methodology.

Deploy on Heroku

You will need to set required environment variables on Heroku.

heroku config:set COOKIE_SECRET=unsafe-cookie-secret-for-heroku
heroku config:set DEBUG_DUMMY_SMTP=1
