Visit https://atlas.mitre.org for more information. 4 | 5 | This repository contains tactics, techniques, mitigations, case studies, and other data used by the ATLAS website and associated tools. 6 | 7 | ## Distributed files 8 | 9 | Located the `dist` directory: 10 | 11 | - `ATLAS.yaml` 12 | + All ATLAS-related data available in one file 13 | + See the schemas and usage below for more details. Top-level keys include: 14 | ```yaml 15 | id: ATLAS 16 | name: Adversarial Threat Landscape for AI Systems 17 | version: Version number for this data release 18 | 19 | matrices: List of matrix data 20 | - id: ATLAS 21 | name: ATLAS Matrix 22 | tactics: List of tactic objects 23 | techniques: List of technique and subtechnique objects 24 | mitigations: List of mitigation objects 25 | 26 | case-studies: List of case study objects 27 | ``` 28 | - `schemas/` 29 | + Optional JSON Schema files for validation use 30 | + `atlas_output_schema.json` 31 | * Describes the `ATLAS.yaml` format 32 | + `atlas_website_case_study_schema.json` 33 | * Describes the case study file format 34 | 35 | ### Getting the files 36 | 37 | Clone this repository to get access to the distributed files, or alternatively directly access via raw GitHub link. 38 | 39 | #### As a Git submodule 40 | 41 | The [ATLAS Website](https://github.com/mitre-atlas/atlas-website) uses this data repository as a Git submodule for access to the distributed files. 42 | 43 | To add this repository as a submodule to your own repository, run the following which clones into the directory `atlas-data`. 44 | 45 | ```bash 46 | git submodule add -b main 47 | ``` 48 | 49 | Once the submodule is available, run the following once to sparse checkout only the necessary files in the `dist` directory. Assumes that the submodule is available at the path `atlas-data`. 50 | ```bash 51 | git -C atlas-data config core.sparseCheckout true 52 | echo 'dist/*' >> .git/modules/atlas-data/info/sparse-checkout 53 | git submodule update --force --checkout atlas-data 54 | ``` 55 | 56 | To update `atlas-data`, run `git submodule update --remote` to get the latest from its main branch, then commit the result. 57 | 58 | ### Example usage 59 | 60 | The following code blocks show examples of parsing ATLAS data. Assume `atlas_data_filepath` holds the path to the `ATLAS.yaml` file. 61 | 62 | #### Python 63 | ```python 64 | # pip install pyyaml 65 | import yaml 66 | 67 | with open(atlas_data_filepath) as f: 68 | # Parse YAML 69 | data = yaml.safe_load(f) 70 | 71 | first_matrix = data['matrices'][0] 72 | tactics = first_matrix['tactics'] 73 | techniques = first_matrix['techniques'] 74 | 75 | studies = data['case-studies'] 76 | ``` 77 | 78 | #### NodeJS 79 | ```js 80 | const fs = require('fs') 81 | // npm install js-yaml 82 | const yaml = require('js-yaml') 83 | 84 | fs.readFile(atlas_data_filepath, 'utf-8', (_, contents) => { 85 | // Parse YAML 86 | const data = yaml.load(contents) 87 | 88 | const first_matrix = data['matrices'][0] 89 | 90 | const tactics = first_matrix['tactics'] 91 | const techniques = first_matrix['techniques'] 92 | 93 | const studies = data['case-studies'] 94 | }) 95 | ``` 96 | 97 | ### JSON Schema validation example 98 | 99 | JSON Schema files are generated from this project's internal [schemas](schemas/README.md) for other tools to use. For example, the ATLAS website validates uploaded case study files against the case study schema file with the following: 100 | 101 | #### NodeJS 102 | 103 | ```js 104 | // npm install jsonschema 105 | import { validate } from 'jsonschema' 106 | import caseStudySchema from '' 107 | 108 | // Assume this is a populated website case study object 109 | const caseStudyObj = {...} 110 | 111 | // Validate case study object against schema and emit errors that may occur from nested `anyOf` validations 112 | const validatorResult = validate(caseStudyObj, caseStudySchema, { nestedErrors: true }) 113 | 114 | if (validatorResult.valid) { 115 | // Good 116 | } else { 117 | // Process validatorResult.errors 118 | } 119 | 120 | ``` 121 | 122 | ## Development 123 | 124 | This repository also contains the source data and scripts to customize and expand the ATLAS framework. See [setup instructions](tools/README.md#development-setup) and the READMEs in each directory linked below for usage. 125 | 126 | - [Data](data/README.md) holds templated data for ATLAS tactics, techniques, and case studies, from which `ATLAS.yaml` is generated. 127 | - [Schemas](schemas/README.md) defines each ATLAS object type and ID. 128 | - [Tools](tools/README.md) contains scripts to generate the distributed files and import data files. 129 | 130 | **Tests** 131 | 132 | This project uses `pytest` for data validation. See [tests](tests/README.md) for more information. 133 | 134 | 135 | ## Related work 136 | 137 | ATLAS is modeled after the [MITRE ATT&CK® framework](https://attack.mitre.org). ATLAS tactics and techniques can be complementary to those in ATT&CK. 138 | 139 | ATLAS data is also available in [STIX and ATT&CK Navigator layer formats](https://github.com/mitre-atlas/atlas-navigator-data) for use with the [ATLAS Navigator](https://mitre-atlas.github.io/atlas-navigator/). 140 | -------------------------------------------------------------------------------- /data/README.md: -------------------------------------------------------------------------------- 1 | # Data 2 | 3 | ATLAS data is stored in YAML files designed to be easy to read and edit, as well as to load, parse, and validate. Each file contains a standard YAML 1.1 document. 4 | 5 | ## Files 6 | 7 | `data.yaml` is the entry point for data definition. It describes the ID, which will become the name of the output YAML file, as well as listing relative paths to matrix directories and other top-level data. 8 | 9 | 10 | For example, the ATLAS `data.yaml` is as follows: 11 | ```yaml 12 | --- 13 | 14 | id: ATLAS 15 | name: Adversarial Threat Landscape for AI Systems 16 | version: 4.1.0 17 | 18 | matrices: 19 | - !include . 20 | 21 | data: 22 | - !include case-studies/*.yaml 23 | ``` 24 | 25 | ## Matrices 26 | 27 | A matrix directory contains a `matrix.yaml` and data object files. 28 | 29 | Files in the ATLAS matrix directory: 30 | - `matrix.yaml` contains metadata, tactics in matrix order, and relative filepaths to the other data files below. 31 | - `tactics.yaml` contains ATLAS tactics, which represent adversary goals. 32 | - `techniques.yaml` contains ATLAS techniques and subtechniques, which represent the means by which adversaries achieve tactical goals. 33 | 34 | ## Other top-level data 35 | Top-level data can reference data objects across matrices. 36 | 37 | - `case-studies/` is a directory containing ATLAS case study files, which describe select machine learning attack incidents and how they map to the ATLAS framework. 38 | 39 | ## Anchors and templates 40 | 41 | Each referenceable data object has a YAML anchor, which is prefaced with `&`. For example, a technique object defined in `techniques.yaml`: 42 | 43 | ```yaml 44 | - &supply_chain 45 | id: AML.T0010 46 | name: AI Supply Chain Compromise 47 | object-type: technique 48 | ``` 49 | 50 | Anchors are used as variable names throughout the files in template expressions, wrapped with `{{ }}`. 51 | 52 | ```jinja 53 | This data may be introduced to a victim system via [{{supply_chain.name}}](/techniques/{{supply_chain.id}}). 54 | ``` 55 | 56 | When using `tools/create_matrix.py` to generate the fully-populated `ATLAS.yaml` data file, these source files are evaluated as templates. The output of the evaluating the example above: 57 | 58 | ```md 59 | This data may be introduced to a victim system via [ML Supply Chain Compromise](/techniques/AML.T0010) 60 | ``` 61 | 62 | ## Updating the data 63 | 64 | ### Tactics and techniques 65 | 66 | Modify `tactics.yaml` and `techniques.yaml` for changes to the main ATLAS matrix. 67 | 68 | Ensure that object IDs are unique and follow the patterns defined in the schema. See definitions in `schemas` for ID patterns and object schemas. 69 | 70 | ### Case studies 71 | 72 | Case study files, such as those downloaded from the ATLAS website, can be added via the `tools/import_case_study_file.py` script. 73 | 74 | To import one or more case study files , run this from the project root: 75 | ``` 76 | python -m tools.import_case_study_file 77 | ``` 78 | 79 | Each imported file has hardcoded tactic and technique IDs replaced with anchors, is assigned a case study ID, and is output `data/case-studies/.yaml`. 80 | 81 | ### Custom data 82 | 83 | Custom data objects can also be added to matrices as new YAML files in `matrix.yaml` files: 84 | 85 | ```yaml 86 | data: 87 | - !include tactics.yaml # Path to YAML file containing ATLAS objects 88 | - !include techniques.yaml # Relative to this data directory 89 | - !include case-studies/*.yaml # Wildcard syntax is supported 90 | - !include custom-objs.yaml # Add other custom files 91 | ``` 92 | 93 | #### Referencing other YAML files 94 | 95 | The `!include` directive accepts relative filepaths to either: 96 | 1. A named YAML file containing a list of data objects, or 97 | 2. A directory containing YAML files with a single data object in each file, specified using the wildcard syntax above 98 | 99 | Objects added via the `!include` syntax can be found in re-generated `ATLAS.yaml` under `matrices`, with a key that is a plural version of the object's `object-type` field. 100 | 101 | ### Additional matrices 102 | 103 | To add a new matrix, create a new directory inside `data` containing a `matrix.yaml`. 104 | 105 | In this example, we've created a new directory called `my-matrix` with the `matrix.yaml` below This new matrix has its own tactics and techniques files. 106 | 107 | ```yaml 108 | --- 109 | 110 | id: custom-matrix 111 | name: Custom Matrix 112 | 113 | tactics: 114 | - "{{hello.id}}" 115 | 116 | data: 117 | - !include my-tactics.yaml 118 | - !include my-techniques.yaml 119 | ``` 120 | 121 | Lastly, update `data.yaml` to include the relative path to the new matrix directory. 122 | 123 | ```yaml 124 | matrices: 125 | - !include . 126 | - !include my-matrix 127 | ``` 128 | 129 | ### Output generation 130 | 131 | To re-generate `dist/ATLAS.yaml` after modifying these source files, run this from the project root: 132 | ``` 133 | python tools/create_matrix.py 134 | ``` 135 | 136 | Use the argument `-o ` to output `ATLAS.yaml` into another directory. 137 | -------------------------------------------------------------------------------- /data/case-studies/AML.CS0000.yaml: -------------------------------------------------------------------------------- 1 | --- 2 | id: AML.CS0000 3 | name: Evasion of Deep Learning Detector for Malware C&C Traffic 4 | object-type: case-study 5 | summary: 'The Palo Alto Networks Security AI research team tested a deep learning 6 | model for malware command and control (C&C) traffic detection in HTTP traffic. 7 | 8 | Based on the publicly available [paper by Le et al.](https://arxiv.org/abs/1802.03162), 9 | we built a model that was trained on a similar dataset as our production model and 10 | had similar performance. 11 | 12 | Then we crafted adversarial samples, queried the model, and adjusted the adversarial 13 | sample accordingly until the model was evaded.' 14 | incident-date: 2020-01-01 15 | incident-date-granularity: YEAR 16 | procedure: 17 | - tactic: '{{reconnaissance.id}}' 18 | technique: '{{victim_research_preprint.id}}' 19 | description: 'We identified a machine learning based approach to malicious URL detection 20 | as a representative approach and potential target from the paper [URLNet: Learning 21 | a URL representation with deep learning for malicious URL detection](https://arxiv.org/abs/1802.03162), 22 | which was found on arXiv (a pre-print repository).' 23 | - tactic: '{{resource_development.id}}' 24 | technique: '{{acquire_ml_artifacts_data.id}}' 25 | description: We acquired a command and control HTTP traffic dataset consisting 26 | of approximately 33 million benign and 27 million malicious HTTP packet headers. 27 | - tactic: '{{ml_attack_staging.id}}' 28 | technique: '{{train_proxy_model.id}}' 29 | description: 'We trained a model on the HTTP traffic dataset to use as a proxy for 30 | the target model. 31 | 32 | Evaluation showed a true positive rate of ~ 99% and false positive rate of ~ 0.01%, 33 | on average. 34 | 35 | Testing the model with a HTTP packet header from known malware command and control 36 | traffic samples was detected as malicious with high confidence (> 99%).' 37 | - tactic: '{{ml_attack_staging.id}}' 38 | technique: '{{craft_adv_manual.id}}' 39 | description: We crafted evasion samples by removing fields from packet header which 40 | are typically not used for C&C communication (e.g. cache-control, connection, 41 | etc.). 42 | - tactic: '{{ml_attack_staging.id}}' 43 | technique: '{{verify_attack.id}}' 44 | description: We queried the model with our adversarial examples and adjusted them 45 | until the model was evaded. 46 | - tactic: '{{defense_evasion.id}}' 47 | technique: '{{evade_model.id}}' 48 | description: 'With the crafted samples, we performed online evasion of the ML-based 49 | spyware detection model. 50 | 51 | The crafted packets were identified as benign with > 80% confidence. 52 | 53 | This evaluation demonstrates that adversaries are able to bypass advanced ML detection 54 | techniques, by crafting samples that are misclassified by an ML model.' 55 | target: Palo Alto Networks malware detection system 56 | actor: Palo Alto Networks AI Research Team 57 | case-study-type: exercise 58 | references: 59 | - title: 'Le, Hung, et al.

-------------------------------------------------------------------------------- 1 | # Schemas 2 | 3 | The project uses the [schema library](https://github.com/keleshev/schema) to define and validate its data. 4 | 5 | - `atlas_id.py` defines ATLAS ID regular expression patterns. 6 | - `atlas_matrix.py` holds the schema for the `ATLAS.yaml` file. 7 | - `atlas_obj.py` holds schemas for tactic, technique, subtechnique, case study, and other data objects. 8 | 9 | ## Usage 10 | 11 | The schemas in this directory are used as test fixures in `conftest.py`. `tests/schema_validation.py` validates each ATLAS data object. 12 | 13 | Additionally, JSON Schema files for `ATLAS.yaml` and website case study files are available at `dist/schemas/` for other tools to use. For example, the ATLAS website validates uploaded case study files against the case study schema file. 14 | 15 | ### Output generation 16 | 17 | To re-generate JSON Schema files after modifying the schemas in this directory, run this from the project root: 18 | ``` 19 | python -m tools.generate_schema 20 | ``` 21 | -------------------------------------------------------------------------------- /schemas/atlas_id.py: -------------------------------------------------------------------------------- 1 | from schema import Regex, Schema 2 | 3 | """Describes ATLAS ID schemas.""" 4 | 5 | # Constants for ID parts 6 | 7 | # Examples of ID Prefixes include, but are not limited to: 8 | # ABC. || ABC123. || ABC.XYZ. || ABC.XYZ789.QW3RTY. 9 | ID_PREFIX_PATTERN = ( 10 | r'(?:' # Start a non-capturing group 11 | r'[A-Z]+' # ID must start with uppercase letters 12 | r'\d*' # Optionally followed by a set of numbers 13 | r'\.' # Then a dot 14 | r')+' # There can be one or more of these patterns in a row 15 | ) 16 | 17 | # Number of digits allowed in the ID portion of a the top-level object and sub-level object 18 | ID_NUM_PATTERN_TOP_LEVEL = r'\d{4}' # i.e. T1234 19 | ID_NUM_PATTERN_SUB_LEVEL = r'\d{3}' # i.e. T0000.123 20 | 21 | FULL_ID_PATTERN = ( 22 | rf'{ID_PREFIX_PATTERN}' # Prefix 23 | r'[A-Z]+' # Some identifier, TA, T, CS, anything 24 | rf'{ID_NUM_PATTERN_TOP_LEVEL}' # Followed by the numbers 25 | rf'(?:\.{ID_NUM_PATTERN_SUB_LEVEL})?' # optionally followed by a .123 26 | ) 27 | 28 | # Helper methods for ID formats 29 | def create_top_level_object_id(object_prefix): 30 | """Returns a full ID for a top-level data object. 31 | 32 | Ex.
