Problem statement

This article explains how to query users blocked by brute force protection using the management API.

Solution

Users blocked by brute force protection do not have the blocked: true attribute, and therefore, it’s not possible to include these users by using such a filter as well.

  • To find users blocked by brute force, make a separate request for each user to the Get a user’s blocks endpoint.
    • This endpoint will return a response like the following:
{"blocked_for":[{"identifier":"[user.email@domain.com](mailto:user.email@domain.com)","connection":"Username-Password-Authentication","ip":"1.2.3.4"}]}

Note: This will need to make a separate request for each user, so it will take a long time if you have a large number of users.

  • Another solution would be to set up a log stream with a third-party service.
    • Filter for limit_wc events and make a record of blocked users.
    • Also, check for ublkdu events so they can be removed once the block is released.
    • The main drawback of this approach is it involves a lot more complexity and additional infrastructure.
