Detection: CodeBuild Project Environment Variable Updated

Overview

Detect when an environment variable in an AWS CodeBuild project was updated. Unauthorized or unintended changes to environment variables can compromise build integrity, expose sensitive data, or disrupt the build pipeline. Monitoring these updates ensures the security of the build process and safeguards critical resources.

Usage

Run the detection in your terminal:

powerpipe detection run aws_cloudtrail_log_detections.detection.codebuild_project_environment_variable_updated

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe detection run aws_cloudtrail_log_detections.detection.codebuild_project_environment_variable_updated --share

SQL

This detection uses a named query:

select
  tp_timestamp as timestamp,
string_split(event_source, '.')[1] || ':' || event_name as operation,
request_parameters ->> 'name' as resource,
user_identity.arn as actor,
tp_source_ip as source_ip,
tp_index as account_id,
aws_region as region,
tp_id as source_id,
*

from
  aws_cloudtrail_log
where
  event_source = 'codebuild.amazonaws.com'
  and event_name = 'UpdateProject'
  and (request_parameters -> 'environment' -> 'environmentVariables') is not null
  and error_code is null

order by
  event_time desc;
