IBM COS HMAC credential detected in code

Rule Details

Cortex AppSec Rule ID	APPSEC_SECRET_8
Category	Cloud Service Provider Keys
Severity	LOW
Framework	Git

Impact

IBM COS HMAC Credentials (Access Key/Secret Key) grant S3-compatible access to IBM Cloud Object Storage.

Exposure allows an attacker to upload, download, or delete objects, resulting in data breaches, data corruption, or unauthorized usage charges.

How to Fix

To remediate exposed Cloud & Infrastructure credentials:

1. Log in to your cloud provider's console.
2. Locate the identity or service account associated with the compromised credentials.
3. Revoke or deactivate the compromised keys immediately.
4. Generate a new set of credentials.
5. Update your environment variables, secrets manager, or pipelines with the new values.

Next, remove the secret from your codebase:

1. Locate the exposed secret in your codebase.
2. Replace the hardcoded value with a secure variable or reference.

Finally, clean your version control history:

1. Permanently remove the sensitive data from your version control history to ensure it cannot be retrieved.

Warning: Revoking infrastructure keys may cause immediate downtime. Ensure you have identified all dependent services before revoking.
