Osquery

Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. Zentral can act as a remote server for Osquery, for configuration, query runs, file carvings, and log collection.

Zentral configuration

To activate the osquery module, you need to add a zentral.contrib.osquery section to the apps section in base.json.

HTTP API

Requests

Authentication

API requests are authenticated using a token in the Authorization HTTP header.

To get a token, you can create a service account. As a superuser, go to Setup > Manage users, and in the "Service accounts" subsection, click on the [Create] button. Pick a name for your service account and [Save]. You will be redirected to a token view. The token is only displayed once. To reveal it, click on the eye icon. Once you have saved it (in a password manager, in a configuration variable, …), you can click on the [OK] button.

You can also add an API token to a normal user, although it is not recommended. To do so, click on the user in the User list, and click on the [+] button next to the API token boolean.

If you have lost or leaked a token, you can delete it by clicking on the user or service account name, and then click on the 🗑 next to the API token boolean.

The format for the Authorization header is the following:

Authorization: Token the_token_string

Content type

Zentral will parse the body of the request based on the Content-Type HTTP header:

• Content-Type: application/json
• Content-Type: application/x-osquery-conf
• Content-Type: application/yaml

/api/osquery/packs/<slug:slug>/

Create or update a standard Osquery pack.

• method: PUT, DELETE

This endpoint is designed to create or update a standard Osquery pack.

Examples

pack.json

{
  "name": "First pack",
  "platform": "darwin",
  "queries": {
    "Leverage-A_1": {
      "query" : "select * from launchd where path like '%UserEvent.System.plist';",
      "interval" : "3600",
      "version": "1.4.5",
      "description" : "(http://www.intego.com/mac-security-blog/new-mac-trojan-discovered-related-to-syria/)",
      "value" : "Artifact used by this malware"
    },
    "Leverage-A_2": {
      "query" : "select * from file where path = '/Users/Shared/UserEvent.app';",
      "interval" : "3600",
      "version": "1.4.5",
      "description" : "(http://www.intego.com/mac-security-blog/new-mac-trojan-discovered-related-to-syria/)",
      "value" : "Artifact used by this malware"
    }
  }
}

PUT the pack.json file to Zentral:

$ curl -XPUT \
  -H "Authorization: Token $ZTL_API_TOKEN" \
  -H 'Content-Type: application/json' \
  -d @pack.json \
  "https://zentral.example.com/api/osquery/packs/first-pack-slug/" \
  |python3 -m json.tool

You should get a response close to this one:

{
  "pack": {
    "pk": 1,
    "slug": "first-pack-slug"
  },
  "result": "created",
  "query_results": {
    "created": 2,
    "deleted": 0,
    "present": 0,
    "updated": 0
  }
}

If you PUT the same file again, you will get this answer:

{
  "pack": {
    "pk": 1,
    "slug": "first-pack-slug"
  },
  "result": "present",
  "query_results": {
    "created": 0,
    "deleted": 0,
    "present": 2,
    "updated": 0
  }
}

If you make a DELETE request on the same URL, the pack and all its rules will be deleted:

$ curl -XDELETE \
  -H "Authorization: Token $ZTL_API_TOKEN" \
  -H 'Content-Type: application/json' \
  "https://zentral.example.com/api/osquery/packs/first-pack-slug/" \
  |python3 -m json.tool

You should get a response close to this one:

{
  "pack": {
    "pk": 1,
    "slug": "first-pack-slug"
  },
  "result": "deleted",
  "query_results": {
    "created": 0,
    "deleted": 2,
    "present": 0,
    "updated": 0
  }
}

If the pack is in the osquery format (broken JSON), with line-wrapping characters, or comments, use the application/x-osquery-conf content type.

pack.conf (Real examples are available in the osquery repository.)

{
  // Do not use this query in production!!!
  "platform": "darwin",
  "queries": {
    "WireLurker": {
      "query" : "select * from launchd where \
        name = 'com.apple.periodic-dd-mm-yy.plist';",
      "interval" : "3600",
      "version": "1.4.5",
      "description" : "(https://github.com/PaloAltoNetworks-BD/WireLurkerDetector)",
      "value" : "Artifact used by this malware - 🔥"
      # 🧨
    }
  }
}

$ curl -XPUT \
  -H "Authorization: Token $ZTL_API_TOKEN" \
  -H 'Content-Type: application/x-osquery-conf' \
  --data-binary @pack.conf \
  "https://zentral.example.com/api/osquery/packs/second-pack-slug/" \
  |python3 -m json.tool

You should get a response close to this one:

{
  "pack": {
    "pk": 2,
    "slug": "second-pack-slug"
  },
  "result": "created",
  "query_results": {
    "created": 1,
    "deleted": 0,
    "present": 0,
    "updated": 0
  }
}

You can also use a YAML payload, with the application/yaml content type.

pack.yml
