Overview

The team at MITRE recently announced the launch of ATT&CK v16.0.

We are big users of ATT&CK, using it to add additional context to our intelligence. You might have seen my fanboy post earlier this year describing the structure of the ATT&CK framework.

Whilst the ATT&CK team keep a great change-log in their release notes, I wanted to dive deeper into the changes to better understand the changes.

This post walks you through my analysis.

Follow along

In this post I am going to provide ArangoDB queries you can use to analyse and filter MITRE ATT&CK data.

If you would like to follow along, and keep a searchable copy of ATT&CK locally, you can import the data using stix2arango.

Once you’ve installed stix2arango, you can run the following command to import all versions of the MITRE ATT&CK Enterprise, ICS, and Mobile datasets;

python3 utilities/arango_cti_processor/insert_archive_attack_enterprise.py \
    --database blog_demo \
    --ignore_embedded_relationships True && \
python3 utilities/arango_cti_processor/insert_archive_attack_ics.py \
    --database blog_demo \
    --ignore_embedded_relationships True && \
python3 utilities/arango_cti_processor/insert_archive_attack_mobile.py \
    --database blog_demo \
    --ignore_embedded_relationships True

You can then use the query interface in the ArangoDB UI to run the AQL queries in this post.

Note, in this post I show queries searching the Enterprise domain (mitre_attack_enterprise_vertex_collection), but show results for all matrices. To get the data for each matrix all you need to do is modify enterprise for ics or mobile to get the results for the specified matrix.

ATT&CK through the ages

To begin, here is a query that shows the growth of the ATT&CK matrices over each release;

FOR doc IN mitre_attack_enterprise_vertex_collection
FILTER doc._stix2arango_note != "automatically imported on collection creation"
AND doc.x_mitre_deprecated != true
AND doc.revoked != true
COLLECT version = doc._stix2arango_note WITH COUNT INTO count
RETURN { "version": version, "count": count }

ATT&CK Enterprise Objects by version

ATT&CK Mobile Objects by version

ATT&CK ICS Objects by version

ATT&CK objects changes between version 15.1 and 16.0

This query looks at each object type and shows the count of those that have been changed, added, deprecated, revoked, or have stayed the same between 15.1 and 16.0;

FOR doc IN mitre_attack_enterprise_vertex_collection
FILTER doc._stix2arango_note IN ["v15.1", "v16.0"]
COLLECT id = doc.id, type = doc.type INTO groupedDocs

LET versions = groupedDocs[*].doc
LET createdDates = UNIQUE(versions[*].created)
LET modifiedDates = UNIQUE(versions[*].modified)
LET count_versions = LENGTH(versions)

LET deprecatedInV16 = LENGTH(FOR v IN versions FILTER v._stix2arango_note == "v16.0" AND v.x_mitre_deprecated == true RETURN v) > 0
LET deprecatedInV15 = LENGTH(FOR v IN versions FILTER v._stix2arango_note == "v15.1" AND v.x_mitre_deprecated == true RETURN v) > 0

LET revokedInV16 = LENGTH(FOR v IN versions FILTER v._stix2arango_note == "v16.0" AND v.revoked == true RETURN v) > 0
LET revokedInV15 = LENGTH(FOR v IN versions FILTER v._stix2arango_note == "v15.1" AND v.revoked == true RETURN v) > 0

// Filter out results where x_mitre_deprecated or revoked is true in both versions
FILTER NOT (deprecatedInV15 == true AND deprecatedInV16 == true)
FILTER NOT (revokedInV15 == true AND revokedInV16 == true)

LET status = (
    count_versions == 1 ? "new" :
    (revokedInV16 == true AND revokedInV15 == false ? "revoked" :
    (deprecatedInV16 == true AND deprecatedInV15 == false ? "deprecated" :
    (LENGTH(createdDates) == 1 AND LENGTH(modifiedDates) == 1 ? "unchanged" : "changed")))
)

COLLECT finalStatus = status, finalType = type WITH COUNT INTO count

// Aggregate results by status
COLLECT status = finalStatus INTO typeCounts = {
  "type": finalType,
  "count": count
}

// Construct dynamic columns for each type
RETURN MERGE(
  { "status": status },
  ZIP(
    typeCounts[*].type,
    typeCounts[*].count
  )
)

ATT&CK Enterprise Object type by version

ATT&CK Mobile Object type by version

ATT&CK ICS Object type by version

New ATT&CK objects changes between version v15.1 and v16.0

This query will produce a list of objects that have been added in version 16.0;

FOR doc IN mitre_attack_enterprise_vertex_collection
FILTER doc._stix2arango_note IN ["v15.1", "v16.0"]
COLLECT id = doc.id INTO groupedDocs

LET versions = groupedDocs[*].doc
LET count_versions = LENGTH(versions)

// Only include objects that are classified as "new" (present in only one version)
FILTER count_versions == 1

// Extract external_id where source_name is "mitre-attack"
LET mitre_attack_id = FIRST(
    FOR ref IN versions[0].external_references
    FILTER ref.source_name == "mitre-attack"
    RETURN ref.external_id
)

// Return only the specified fields
RETURN {
    "type": versions[0].type,
    "external_id": mitre_attack_id,
    "name": versions[0].name
}

ATT&CK changes

To get a similar list of changed objects between versions, you can run the query;

FOR doc IN mitre_attack_enterprise_vertex_collection
FILTER doc._stix2arango_note IN ["v15.1", "v16.0"]
COLLECT id = doc.id INTO groupedDocs

LET versions = groupedDocs[*].doc
LET createdDates = UNIQUE(versions[*].created)
LET modifiedDates = UNIQUE(versions[*].modified)
LET count_versions = LENGTH(versions)

LET deprecatedInV16 = LENGTH(FOR v IN versions FILTER v._stix2arango_note == "v16.0" AND v.x_mitre_deprecated == true RETURN v) > 0
LET deprecatedInV15 = LENGTH(FOR v IN versions FILTER v._stix2arango_note == "v15.1" AND v.x_mitre_deprecated == true RETURN v) > 0

LET revokedInV16 = LENGTH(FOR v IN versions FILTER v._stix2arango_note == "v16.0" AND v.revoked == true RETURN v) > 0
LET revokedInV15 = LENGTH(FOR v IN versions FILTER v._stix2arango_note == "v15.1" AND v.revoked == true RETURN v) > 0

// Filter out results where x_mitre_deprecated or revoked is true in both versions
FILTER NOT (deprecatedInV15 == true AND deprecatedInV16 == true)
FILTER NOT (revokedInV15 == true AND revokedInV16 == true)

// Only include objects that are classified as "changed" (present in both versions with differences in created or modified dates)
LET status = (
    count_versions == 1 ? "new" :
    (revokedInV16 == true AND revokedInV15 == false ? "revoked" :
    (deprecatedInV16 == true AND deprecatedInV15 == false ? "deprecated" :
    (LENGTH(createdDates) == 1 AND LENGTH(modifiedDates) == 1 ? "unchanged" : "changed")))
)

FILTER status == "changed"

// Safely extract external_id where source_name is "mitre-attack", handling missing external_references
LET mitre_attack_id = FIRST(
    FOR ref IN versions[0].external_references || []
    FILTER ref.source_name == "mitre-attack"
    RETURN ref.external_id
)

// Return only the specified fields
RETURN {
    "type": versions[0].type,
    "external_id": mitre_attack_id,
    "name": versions[0].name
}

Once you have a list of IDs returned by the above query, you can use the following query to identify the properties changed. For example, here I am comparing T1053.005 (Scheduled Task/Job: Scheduled Task) between version 15.1 and 16.0.

// Specify the ID of the object to compare
LET target_id = "T1053.005"

// Gather both versions
LET docs = (
    FOR doc IN mitre_attack_enterprise_vertex_collection
    FILTER doc._stix2arango_note IN ["v15.1", "v16.0"]
    AND "mitre-attack" IN doc.external_references[*].source_name
    AND target_id IN doc.external_references[*].external_id
    RETURN { "version": doc._stix2arango_note, "doc": doc }
)

// Extract the documents for v15.1 and v16.0
LET v15_1 = FIRST(FOR d IN docs FILTER d.version == "v15.1" RETURN d.doc) || null
LET v16_0 = FIRST(FOR d IN docs FILTER d.version == "v16.0" RETURN d.doc) || null

// Only proceed if both versions are available
RETURN (v15_1 != null AND v16_0 != null) ? {
    "id": target_id,
    "differences": (
        FOR key IN ATTRIBUTES(v15_1)
        FILTER v15_1[key] != v16_0[key]
        AND !STARTS_WITH(key, "_")  // Exclude keys starting with an underscore
        RETURN {
            "field": key,
            "v15.1": v15_1[key],
            "v16.0": v16_0[key]
        }
    )
} : {
    "id": target_id,
    "error": "One or both versions are missing for comparison."

        "v15.1": "Adversaries may abuse the Windows Task Scheduler to perform task scheduling for initial or recurring execution of malicious code. There are multiple ways to access the Task Scheduler in Windows. The [schtasks](https://attack.mitre.org/software/S0111) utility can be run directly on the command line, or the Task Scheduler can be opened through the GUI within the Administrator Tools section of the Control Panel. In some cases, adversaries have used a .NET wrapper for the Windows Task Scheduler, and alternatively, adversaries have used the Windows netapi32 library to create a scheduled task.\n\nThe deprecated [at](https://attack.mitre.org/software/S0110) utility could also be abused by adversaries (ex: [At](https://attack.mitre.org/techniques/T1053/002)), though <code>at.exe</code> can not access tasks created with <code>schtasks</code> or the Control Panel.\n\nAn adversary may use Windows Task Scheduler to execute programs at system startup or on a scheduled basis for persistence.

There are multiple ways to access the Task Scheduler in Windows.

Adversaries may also utilize the Powershell Cmdlet `Invoke-CimMethod`, which leverages WMI class `PS_ScheduledTask` to create a scheduled task via an XML path.(Citation: Red Canary - Atomic Red Team)\n\nAn adversary may use Windows Task Scheduler to execute programs at system startup or on a scheduled basis for persistence.

A shout out to ATT&CK Sync

Having the objects in a database makes them easy to query however you choose.

Though many of you reading this will just want the review changes in a more simple manner. That’s where a nicely crafted web interface on top of these queries helps.

Enter ATT&CK Sync…

The ATT&CK Sync project streamlines upgrades to new versions of MITRE ATT&CK® by providing tools and resources to migrate existing projects to current ATT&CK versions in a timely and efficient manner.

ATT&CK Sync T1053.005

Take the T1053.005 example I showed earlier. Whilst it only shows changes to the description, ATT&CK Sync makes it much easier to compare what was actually changed.

In fact, ATT&CK Sync was a big inspiration for the ATT&CK part of CTI Butler (which contains this feature for many popular CTI frameworks, not only ATT&CK).
