Exposure Alerts Service API


An Exposure refers to any unintended release of user credentials on the Internet. This could be due to a data breach at a site, malware that has captured user credentials, a phishing site which has been capturing user credentials, etc. An Exposure occurs when this stolen credential data is then posted or shared in some public or private venue. Enzoic (formerly PasswordPing) routinely scours the web looking for this data and catalogues it into its database. Every time a new list of credentials is found, this is added as a new Exposure in our database.

The Exposure Alerts Service API allows you to register email addresses with Enzoic so you can be notified about future exposures that involve them. The notifications will be made to a webhook URL you establish with Enzoic. See the Webhooks section for more details. For general information on webhooks, see webhooks.org.

Webhooks


To use the Exposure Alerts Service API, it is necessary to setup your Webhook with Enzoic. You will need to specify a URL on your end that will be called with a POST whenever a notification is made. You will also receive a Webhook Key and Webhook Secret which will be passed to your endpoint via basic HTTP authentication.

NOTE: Webhook notifications will be sent from IP address: 52.42.159.171. You may need to update your firewall rules accordingly.

Webhook POST Body

The content of the POST body for webhook notifications will be a JSON object with the members specified below:

Member Type Description
date date The date/time (in GMT) that the Exposure was found
exposureID string The ID of the Exposure. This can subsequently be used with the GET Exposure Details API to retrieve additional information about the Exposure.
username string The username/email address which was exposed.
usernameHash string The SHA-256 hash of the username/email address exposed.

An example POST body:

{ 
  "username": "sample@email.tst",
  "usernameHash": "de34a09f96a6677f8a4e0a17545a20e0b60a2f093879c82ed36cff75930d5814",
  "date": "2017-01-17T04:51:05.1915231Z"
  "exposureID": "583d32144d6db21a908faa11"
}

Webhook Authentication

For security reasons, you should authenticate calls to your Webhook endpoint. To facilitate this, you will be provided with Webhook Key and a Webhook Secret when you configure your Webhook in Enzoic. These will be passed as a standard basic authentication HTTP header in a similar manner to how you construct authentication headers to call the Enzoic API: the Webhook Key is the username and the Webhook Secret is the password. As per the standard, the authentication header passed to your endpoint is constructed as follows:

authorization: basic Base64({Webhook Key}:{Webhook Secret})

Testing Your Implementation

Once you have your webhook up and publicly accessible, you can verify all is working using the Webhook Test REST Call below. This will make a POST to your URL with test data.

GET Webhook Test


https://api.enzoic.com/webhook-test

This call will cause a test POST to be sent to the webhook URL registered to your account. This allows you to verify that your webhook URL is setup properly and able to receive Exposure Alerts from Enzoic.

See Using Enzoic for general instructions on using the API.

Request

There are no request parameters required for this call.

Response

Response Description
200 The call was successful. Your webhook should receive a test POST as a result.
404 No webhook URL is registered for your account. Contact support to have a URL added.

Example

curl --header "authorization: basic {your auth string}" --header "content-type: application/json" https://api.enzoic.com/webhook-test
