Overview

• Detecting Publicly Exposed Secrets on GitHub at Scale
  • xGitGuard is an AI-based system designed and developed by the Comcast Cybersecurity Research and Development team that detects secrets (e.g., API tokens, usernames, passwords, etc.) exposed on GitHub. xGitGuard uses advanced Natural Language Processing to detect secrets at scale and with appropriate velocity in GitHub repositories.
• What are Secrets?
  • Credentials
  • Usernames & passwords, server credentials, account credentials, etc.
  • Keys/Tokens
  • Service API tokens (AWS, Azure, etc), encryption keys, etc.

Enterprise Github Secrets Detection

API Configuration Setup

• Setup the system Environment variable below for accessing GitHub
  • GITHUB_ENTERPRISE_TOKEN - Enterprise GitHub API Token with full scopes of repository and user.
  • Refer to the GitHub documentation How To Get GitHub API Token for help
• Update the following configs with your Enterprise Name in config file xgg_configs.yaml in config Data folder xgitguard\config\*
  • enterprise_api_url: https://github.<<Enterprise_Name>>.com/api/v3/search/code
  • enterprise_pre_url: https://github.<<Enterprise_Name>>.com/api/v3/repos/
  • url_validator: https://github.<<Enterprise_Name>>.com/api/v3/search/code
  • enterprise_commits_url: https://github.<<Enterprise_Name>>.com/api/v3/repos/{user_name}/{repo_name}/commits?path={file_path}

Running Enterprise Secret Detection

• Traverse into the github-enterprise script folder

  cd github-enterprise

Enterprise Credential Secrets Detection

Detections Without Additional ML Filter

By default, the Credential Secrets Detection script runs for given Secondary Keywords and extensions without ML Filter.

# Run with Default configs
python enterprise_cred_detections.py

Detection With ML Filter

xGitGuard also has an additional ML filter where users can collect their organization/targeted data and train their model. Having this ML filter helps to reduce the false positives from the detection.

Pre-Requisite To Use the ML Filter

User Needs to follow the below process to collect data and train the model to use ML filter.

• Follow ML Model Training

NOTE :

• To use ML Filter, ML training is mandatory. This includes data collection, feature engineering & model persisting.
• This process is going to be based on user requirements. It can be one time or if the user needs to improve the data, then needs to be done periodically.

ML Model Training

Enterprise ML Model Training Procedure

To use ML Feature, ML training is mandatory. It includes data collection, feature engineering & model persisting.

Note: Labelling the collected secret is an important process to improve the ML prediction.

• Traverse into the "ml_training" folder

  cd ml_training

Data Collection

Traverse into the "data collector" folder under ml_training

  cd ml_data_collector\github-enterprise-ml-data-collector

• Credentials

  1. Run for given Secondary Keywords and extensions

     python enterprise_cred_data_collector.py

  2. To run with other parameters, please use help.

     python enterprise_cred_data_collector.py  -h

  3. Training data for Enterprise Creds collected will be placed in xgitguard\output\cred_train_source.csv folder

• Keys & Tokens

  1. Run for given Secondary Keywords and extensions,

     python enterprise_key_data_collector.py

  2. To run with other parameters, please use help.

     python enterprise_key_data_collector.py  -h

  3. Training data for Enterprise Keys and Tokens collected will be placed in xgitguard\output\key_train_source.csv folder

Review & Label the Collected Data

1. By default all the data collected will be labeled as 1 under column "Label" in collected training data indicating the collected secret as a valid one.
2. User needs to review each row in the collected data and update the label value. i.e: if the user thinks collected data is not a secret, then change the value to 0 for that particular row.
3. By doing this, ML will have quality data for the model to reduce false positives.

Feature Engineering

Traverse into the "ml_training" folder

• Credentials

  1. Run with option cred for engineering collected cred data

     python ml_feature_engineering.py cred

  2. By default in Enterprise mode, input will be cred_train_source.csv
  3. Engineered data for Enterprise Creds output will be placed in xgitguard\output\cred_train.csv folder

• Keys & Tokens

  1. Run with option cred for engineering collected keys & tokens data

     python ml_feature_engineering.py key

  2. By default in Enterprise mode, input will be key_train_source.csv
  3. Engineered data for Enterprise Keys & Tokens output will be placed in xgitguard\output\key_train.csv folder

ML Model Creation for Enterprise

Traverse into the "ml_training" folder

• Run training with Cred Training Data and persist model

  python model.py cred

• Run training with Key Training Data and persist model

  python model.py key

• For help on command line arguments, run

  python model.py  -h

  Note: If persisted model xgitguard\output\xgg_*.pickle is not present in the output folder, then use engineered data to create a model and persist it.

Public GitHub ML Model Training Procedure

To use ML Feature, ML training is mandatory. It includes data collection, feature engineering & model persisting.

Note: Labelling the collected secret is an important process to use the ML effectively.

• Traverse into the "models" folder

  cd ml_training

Data Collection :

Traverse into the "data collector" folder

cd ml_training\ml_data_collector\github-public-ml-data-collector

Note: User needs to remove the sample content from primary_keywords.csv and add primary keywords like targeted domain names to be searched in public GitHub.

• Credentials

  1. Run for given Primary Keywords, Secondary Keywords, and extensions

Additional Important Notes

• Users can update confidence_values.csv based on secondary_keys, secondary_creds, extensions value and give scoring from level 0 (lowest) to 5 (highest) to denote associated keyword suspiciousness.
• If users need to add any custom/new secondary creds/keys or extensions to the config files, then the same has to be added in the confidence_values.csv file with respective score level.
• Stop Words provided in config files are very limited and generic.Users need to update stop_words.csv with keywords considered has false postives to filter it out from the detections.
• Users can add additional extensions to extensions.csv to search types of files other than the default list.
• Users can enhance secondary_creds.csv/secondary_keys.csv by adding new patterns to do searches other than the default list.
• Users need to add primary keywords for public search in primary_keywords.csv after removing the sample content.
• In case of GitHub API calls resulting in 403 due to API rate-limit, increase the throttle timeout (github.throttle_time: 10) in the config ("config/xgg_configs.yaml)".
