The OpenCTI integration allows you to ingest data from the OpenCTI threat intelligence platform.

Use this integration to get indicator data from OpenCTI. You can monitor and explore the ingested data on the OpenCTI dashboard or in Kibana's Discover tab. Indicator match rules in Elastic Security can then use the ingested indicator data to generate alerts about detected threats.

Data streams

The OpenCTI integration collects one type of data stream: logs.

Logs are lists of records created over time. Each event in the log data stream collected by the OpenCTI integration is an indicator that can be used to detect suspicious or malicious cyber activity. The data is fetched from OpenCTI's GraphQL API.

Requirements

This integration requires Filebeat version 8.9.0, or later.

It has been updated for OpenCTI version 5.12.24 and requires that version or later.

Setup

For additional information about threat intelligence integrations, including the steps required to add an integration, please refer to the Enable threat intelligence integrations page of the Elastic Security documentation.

When adding the OpenCTI integration, you will need to provide a base URL for the target OpenCTI instance. It should be just the base URL (e.g. https://demo.opencti.io) and not include an additional path for the API or UI.

The simplest authentication method to use is an API key (bearer token). You can find a value for the API key on your profile page in the OpenCTI user interface. Advanced integration settings can be used to configure various OAuth2-based authentication arrangements, and to enter SSL settings for mTLS authentication and for other purposes. For information on setting up the OpenCTI side of an authentication strategy, please refer to OpenCTI's authentication documentation.

Logs

Indicator

The indicator data stream includes indicators of the following types (threat.indicator.type): artifact, autonomous-system, bank-account, cryptocurrency-wallet, cryptographic-key, directory, domain-name, email-addr, email-message, email-mime-part-type, hostname, ipv4-addr, ipv6-addr, mac-addr, media-content, mutex, network-traffic, payment-card, phone-number, process, software, file, text, url, user-account, user-agent, windows-registry-key, windows-registry-value-type, x509-certificate, unknown.

OpenCTI's data model closely follows the STIX standard. It supports complex indicators defined using STIX patterns or other languages, and each indicator can be related to one or more observables. In the ECS threat fields the focus is on atomic indicators. This integration fetches as much data as possible about indicators and their related observables, and populates relevant ECS fields wherever possible. It uses related observables rather than the indicator pattern as the data source for type-specific indicator fields.

Expiration of inactive indicators

The opencti.indicator.invalid_or_revoked_from field is set to the earliest time at which an indicator reaches its valid_until time or is marked as revoked. From that time the indicator should no longer be considered active.

An Elastic Transform is created to provide a view of active indicators for end users. This transform creates destination indices that are accessible via the alias logs-ti_opencti_latest.indicator. When querying for active indicators or setting up indicator match rules, use that alias to avoid false positives from expired indicators.

The dashboards show only active indicators, except the Ingestion dashboard, which shows data from both the source data stream and the indices of the latest indicators.

Indicators that are never expired or revoked will not be removed from the indices of the latest indicators. If accumulation of indicators is a problem there, it can be managed upstream in OpenCTI, or by manually deleting indicators from those indices.

To prevent unbounded growth of the source data stream logs-ti_opencti.indicator-*, it has an index lifecycle management (ILM) policy that deletes records 5 days after ingestion.

Exported fields

Fields for indicators of any type are mapped to ECS fields when possible (primarily threat.indicator.*) and otherwise stored with a vendor prefix (opencti.indicator.*).

Fields for related observables of the various types are always stored under opencti.observable.<type>.* and when possible their values will be copied into corresponding ECS fields.

The related.* fields will also be populated with any relevant data.

Timestamps are mapped as follows:

SourceDestinationDescription
-
@timestamp
Time the event was received by the pipeline
-
event.ingested
Time the event arrived in the central data store
created
event.created
Time of the indicator's creation
modified
threat.indicator.modified_at
Time of the indicator's last modification
valid_from
opencti.indicator.valid_from
Time from which this indicator is considered a valid indicator of the behaviors it is related to or represents
valid_until
opencti.indicator.valid_until
Time at which this indicator should no longer be considered a valid indicator of the behaviors it is related to or represents
-
opencti.indicator.invalid_or_revoked_from
The earliest time at which an indicator reaches its valid_until time or is marked as revoked

The table below lists all opencti.* fields.

The documentation for ECS fields can be found at:

Exported fields

FieldDescriptionType
@timestamp
Time the event was received by the pipeline.
date
data_stream.dataset
Data stream dataset.
constant_keyword
data_stream.namespace
Data stream namespace.
constant_keyword
data_stream.type
Data stream type.
constant_keyword
ecs.version
ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events.
keyword
event.agent_id_status
Agents are normally responsible for populating the agent.id field value. If the system receiving events is capable of validating the value based on authentication information for the client then this field can be used to reflect the outcome of that validation. For example if the agent's connection is authenticated with mTLS and the client cert contains the ID of the agent to which the cert was issued then the agent.id value in events can be checked against the certificate. If the values match then event.agent_id_status: verified is added to the event, otherwise one of the other allowed values should be used. If no validation is performed then the field should be omitted. The allowed values are: verified - The agent.id field value matches expected value obtained from auth metadata. mismatch - The agent.id field value does not match the expected value obtained from auth metadata. missing - There was no agent.id field in the event to validate. auth_metadata_missing - There was no auth metadata or it was missing information about the agent ID.
keyword
event.category
This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. event.category represents the "big buckets" of ECS categories. For example, filtering on event.category:process yields all events relating to process activity. This field is closely related to event.type, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories.
keyword
event.created
event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used.
date
event.dataset
Name of the dataset. If an event source publishes more than one type of log or events (e.g. access log, error log), the dataset is used to specify which one the event comes from. It's recommended but not required to start the dataset name with the module name, followed by a dot, then the dataset name.
keyword
event.id
Unique ID to describe the event.
keyword
event.ingested
Timestamp when an event arrived in the central data store. This is different from @timestamp, which is when the event originally occurred. It's also different from event.created, which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: @timestamp < event.created < event.ingested.
date
event.kind
This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not.
keyword
event.original
Raw text message of entire event. Used to demonstrate log integrity or where the full log message (before splitting it up in multiple parts) may be required, e.g. for reindex. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from _source. If users wish to override this and index this field, please see Field data types in the Elasticsearch Reference.
keyword
event.type
This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types.
keyword
input.type
Input type.
keyword
labels.is_ioc_transform_source
Field indicating if the document is a source for the transform. This field is not added to destination indices to facilitate easier filtering of indicators for indicator match rules.
constant_keyword

For sequences of string with REG_MULTI_SZ, this array will be variable length. For numeric data, such as REG_DWORD and REG_QWORD, this should be populated with the decimal representation (e.g "1").
wildcard
threat.indicator.registry.data.type
Standard registry type for encoding contents
keyword
threat.indicator.registry.hive
Abbreviated name for the hive.
keyword
threat.indicator.registry.key
Hive-relative path of keys.
keyword
threat.indicator.registry.path
Full path, including hive, key and value
keyword
threat.indicator.registry.value
Name of the value written.
keyword
threat.indicator.type
Type of indicator as represented by Cyber Observable in STIX 2.1 or OpenCTI
keyword
threat.indicator.url.domain
Domain of the url, such as "www.elastic.co". In some cases a URL may refer to an IP and/or port directly, without a domain name. In this case, the IP address would go to the domain field. If the URL contains a literal IPv6 address enclosed by [ and ] (IETF RFC 2732), the [ and ] characters should also be captured in the domain field.
keyword
threat.indicator.url.extension
The field contains the file extension from the original request url, excluding the leading dot. The file extension is only set if it exists, as not every url has a file extension. The leading period must not be included. For example, the value must be "png", not ".png". Note that when the file name has multiple extensions (example.tar.gz), only the last one should be captured ("gz", not "tar.gz").
keyword
threat.indicator.url.fragment
Portion of the url after the #, such as "top". The # is not part of the fragment.
keyword
threat.indicator.url.full
If full URLs are important to your use case, they should be stored in url.full, whether this field is reconstructed or present in the event source.
wildcard
threat.indicator.url.full.text
Multi-field of threat.indicator.url.full.
match_only_text
threat.indicator.url.original
Unmodified original url as seen in the event source. Note that in network monitoring, the observed URL may be a full URL, whereas in access logs, the URL is often just represented as a path. This field is meant to represent the URL as it was observed, complete or not.
wildcard
threat.indicator.url.original.text
Multi-field of threat.indicator.url.original.
match_only_text
threat.indicator.url.password
Password of the request.
keyword
threat.indicator.url.path
Path of the request, such as "/search".
wildcard
threat.indicator.url.port
Port of the request, such as 443.
long
threat.indicator.url.query
The query field describes the query string of the request, such as "q=elasticsearch". The ? is excluded from the query string. If a URL contains no ?, there is no query field. If there is a ? but no query, the query field exists with an empty string. The exists query can be used to differentiate between the two cases.
keyword
threat.indicator.url.registered_domain
The highest registered url domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk".
keyword
threat.indicator.url.scheme
Scheme of the request, such as "https". Note: The : is not part of the scheme.
keyword
threat.indicator.url.subdomain
The subdomain portion of a fully qualified domain name includes all of the names except the host name under the registered_domain. In a partially qualified domain, or if the the qualification level of the full name cannot be determined, subdomain contains all of the names below the registered domain. For example the subdomain portion of "www.east.mydomain.co.uk" is "east". If the domain has multiple levels of subdomain, such as "sub2.sub1.example.com", the subdomain field should contain "sub2.sub1", with no trailing period.
keyword
threat.indicator.url.top_level_domain
The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk".
keyword
threat.indicator.url.username
Username of the request.
keyword
threat.indicator.x509.alternative_names
List of subject alternative names (SAN). Name types vary by certificate authority and certificate type but commonly contain IP addresses, DNS names (and wildcards), and email addresses.
keyword
threat.indicator.x509.issuer.common_name
List of common name (CN) of issuing certificate authority.
keyword
threat.indicator.x509.not_after
Time at which the certificate is no longer considered valid.
date
threat.indicator.x509.not_before
Time at which the certificate is first considered valid.
date
threat.indicator.x509.public_key_algorithm
Algorithm used to generate the public key.
keyword
threat.indicator.x509.public_key_exponent
Exponent used to derive the public key. This is algorithm specific.
long
threat.indicator.x509.serial_number
Unique serial number issued by the certificate authority. For consistency, if this value is alphanumeric, it should be formatted without colons and uppercase characters.
keyword
threat.indicator.x509.signature_algorithm
Identifier for certificate signature algorithm. We recommend using names found in Go Lang Crypto library. See https://github.com/golang/go/blob/go1.14/src/crypto/x509/x509.go#L337-L353.
keyword
threat.indicator.x509.subject.common_name
List of common names (CN) of subject.
keyword
threat.indicator.x509.version_number
Version of x509 format.
keyword
