Threat Intel module

edit

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

This module ingests data from a collection of different threat intelligence sources. The ingested data is meant to be used with Indicator Match rules, but is also compatible with other features like Enrich Processors. The related threat intel attribute that is meant to be used for matching incoming source data is stored under the threatintel.indicator.* fields.

The available filesets are:

edit
  • abuseurl: Supports gathering URL entities from Abuse.ch.
  • abusemalware: Supports gathering Malware/Payload entities from Abuse.ch.
  • misp: Supports gathering threat intel attributes from MISP (replaces MISP module).
  • malwarebazaar: Supports gathering Malware/Payload entities from Malware Bazaar.
  • otx: Supports gathering threat intel attributes from AlientVault OTX.
  • anomali: Supports gathering threat intel attributes from Anomali Limo.
  • anomalithreatstream: Supports gathering threat intel attributes from Anomali ThreatStream.
  • recordedfuture: Supports gathering threat intel attributes from Recorded Future.

abuseurl fileset settings

edit

This fileset contacts the abuse.ch API and fetches all new malicious URLs found the last 60 minutes.

To configure the module, please utilize the default URL unless specified as the example below:

- module: threatintel
  abuseurl:
    enabled: true
    var.input: httpjson
    var.url: https://urlhaus-api.abuse.ch/v1/urls/recent/
    var.interval: 60m
var.paths
An array of glob-based paths that specify where to look for the log files. All patterns supported by Go Glob are also supported here. For example, you can use wildcards to fetch all files from a predefined level of subdirectories: /path/to/log/*/*.log. This fetches all .log files from the subfolders of /path/to/log. It does not fetch log files from the /path/to/log folder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.
var.url
The URL of the API endpoint to connect with.
var.interval
How often the API is polled for updated information.
var.proxy_url
Optional URL to use as HTTP proxy.

misp fileset settings

edit

This fileset communicates with a local or remote MISP server. This replaces the older MISP module.

The fileset configuration allows to set the polling interval, how far back it should look initially, and optionally any filters used to filter the results.

- module: threatintel
  misp:
    enabled: true
    var.input: httpjson
    var.url: https://SERVER/events/restSearch
    var.api_token: xVfaM3DSt8QEwO2J1ix00V4ZHJs14nq5GMsHcK6Z
    var.first_interval: 24h
    var.interval: 60m

To configure the output with filters, use fields that already exist on the MISP server, and define either a single value or multiple. By adding a filter, only events that have attributes that match the filter will be returned.

The below filters are only examples, for a full list of all fields please reference the MISP fields located on the MISP server itself.

- module: threatintel
  misp:
    enabled: true
    var.input: httpjson
    var.url: https://SERVER/events/restSearch
    var.api_token: xVfaM3DSt8QEwO2J1ix00V4ZHJs14nq5GMsHcK6Z
    var.filters:
      - type: ["md5", "sha256", "url", "ip-src"]
      - threat_level: 4
    var.first_interval: 24h
    var.interval: 60m
var.paths
An array of glob-based paths that specify where to look for the log files. All patterns supported by Go Glob are also supported here. For example, you can use wildcards to fetch all files from a predefined level of subdirectories: /path/to/log/*/*.log. This fetches all .log files from the subfolders of /path/to/log. It does not fetch log files from the /path/to/log folder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.
var.url
The URL of the API endpoint to connect with.
var.interval
How often the API is polled for updated information.
var.first_interval
How far back to search when retrieving events the first time Filebeat starts up. After the first interval has passed the module itself will use the timestamp from the last response as the filter when retrieving new events.
var.filters
List of filters to apply when retrieving new events from the MISP server, this field is optional and defaults to all events.
var.proxy_url

anomali fileset settings

edit

To configure the module please fill in the credentials, for Anomali Limo (the free Taxii service) these are usually default credentials found at the Anomali Limo webpage Anomali Limo offers multiple sources called collections. Each collection has a specific ID, which then fits into the url used in this configuration. A list of different collections can be found using the credentials at Limo Collections.

The example below uses the collection of ID 41 as can be seen in the URL.

- module: threatintel
  anomali:
    enabled: true
    var.input: httpjson
    var.url: https://limo.anomali.com/api/v1/taxii2/feeds/collections/41/objects?match[type]=indicator
    var.username: guest
    var.password: guest
    var.interval: 60m

To filter on specific types, you can define var.types as a comma delimited list of object types. This defaults to "indicators".

- module: threatintel
  anomali:
    enabled: true
    var.input: httpjson
    var.url: https://limo.anomali.com/api/v1/taxii2/feeds/collections/41/objects?match[type]=indicator

anomalithreatstream fileset settings

edit

To configure the ThreatStream integration you first need to define an output in the Anomali ThreatStream Integrator using the Elastic SDK provided by Anomali. It will deliver indicators via HTTP or HTTPS to a Filebeat instance running as a server.

Configure an Integrator output with the following settings:

  • Indicator Filter: * (or use any desired filter).
  • SDK Executable Command: /path/to/python /path/to/anomali-sdk/main.py. Adjust the paths to the python executable and the directory where the Elastic SDK has been unpacked.
  • Metadata in JSON Format: {"url": "https://filebeat:8080/", "server_certificate": "/path/to/cert.pem", "secret": "my secret"}.

    • url: Use the host and port where Filebeat will be running, and http or https accordingly.
    • server_certificate: If using HTTPS, absolute path to the server certificate. Otherwise don’t set this field.
    • secret: A shared secret string to authenticate messages between the SDK and Filebeat.

Then configure the anomalithreatstream fileset in Filebeat accordingly:

- module: threatintel
  anomalithreatstream:
    enabled: true
    var.input: http_endpoint
    var.listen_address: 0.0.0.0 # Listen on all interfaces.
    var.listen_port: 8080
    var.secret: 'my secret'
    var.ssl_certificate: path/to/server_ssl_cert.pem
    var.ssl_key: path/to/ssl_key.pem
var.listen_address
Local address to bind the HTTP server to. Use 0.0.0.0 to accept connections from all interfaces.
var.listen_port
Port number to use for the HTTP server.
var.secret
Shared secret between the SDK and Filebeat, used to authenticate messages.
var.ssl_certificate
Path to the public SSL certificate for the HTTPS server. If unset, Filebeat will use unsecure HTTP connections.
var.ssl_key
Path to the certificate’s private key.

Anomali ThreatStream fields are mapped to the following ECS fields:

recordedfuture fileset settings

edit

The recordedfuture fileset fetches intelligence from the Recorded Future Connect API. It supports domain, hash, ip and url data types.

To enable it you need to define the URL to fetch data from. You can construct this URL using the Recorded Future API Explorer. The URL must point to the /search endpoint and contain a suitable limit (how many records to return from a single request) and fields parameters. The entity and timestamps fields are required.

Sample configuration:

- module: threatintel
  recordedfuture:
    enabled: true
    var.input: httpjson
    var.interval: 5m
    var.first_interval: 168h
    var.url: "https://api.recordedfuture.com/v2/ip/search?limit=200&fields=entity,timestamps,risk,intelCard,location&metadata=false"
    var.api_token: "<RF_TOKEN>"

To fetch threat intelligence from multiple data types, you must define more than one instance of the module:

- module: threatintel
  recordedfuture:
    enabled: true
    var.input: httpjson
    var.interval: 5m
    var.first_interval: 168h
    var.url: "https://api.recordedfuture.com/v2/ip/search?limit=200&fields=entity,timestamps,risk,intelCard,location&metadata=false"
    var.api_token: "<RF_TOKEN>"
- module: threatintel
  recordedfuture:
    enabled: true
    var.input: httpjson
    var.interval: 1m
    var.first_interval: 168h
    var.url: "https://api.recordedfuture.com/v2/hash/search?limit=200&fields=entity,fileHashes,timestamps,risk,intelCard,location&metadata=false"
    var.api_token: "<RF_TOKEN>"
var.url
The URL of the API endpoint to connect with.
var.api_token
The API token used to access Recorded Future API.
var.interval
How often the API is polled for updated information.
var.first_interval
How far back to search when retrieving events the first time Filebeat starts up. After the first interval has passed the module itself will use the timestamp from the last response as the filter when retrieving new events.
var.proxy_url
Optional URL to use as HTTP proxy.

Recorded Future fields are mapped to the following ECS fields:
