We've been using CrowdStrike Falcon's intelligence feeds integrated into our internal security dashboard for over a year, primarily on AWS. The primary use case is automated enrichment of our internal event logs. After the latest Falcon platform update (we're on version 6.45), our custom integration pipeline broke completely.
The failure mode is consistent: our service, which polls a specific Falcon API endpoint for the latest IOCs, now receives a 403 Forbidden error. The integration was built using service principles with appropriate API client permissions, and these credentials have not changed. Our logging shows the attempt is being made, but the authorization is rejected at the CrowdStrike side.
Key details of our environment:
* Deployment: AWS Lambda (Python) fetching data, storing in S3, then queried by Athena.
* Authentication: OAuth2 client credentials grant flow.
* Critical API Endpoint: `/intel/combined/indicators/v1`
We've ruled out the obvious:
* Credential rotation or expiry.
* Changes to our IAM roles or VPC configurations.
* Quota exhaustion on our Falcon instance.
This has significant cost implications. The broken pipeline means our security team is manually downloading reports, which increases labor costs and creates latency. Furthermore, the Lambda functions are failing and retrying, incurring unnecessary compute charges, and our downstream Athena queries are now scanning stale data.
Has anyone else experienced a similar break after the 6.45 update? Specifically:
* Were there undocumented changes to the required OAuth2 scopes for intelligence API access?
* Is there a new mandatory parameter or header for the indicator query endpoints?
* Could this be related to a new "data region" configuration that decouples the API gateway from our original Falcon instance?
Any insight into the specific API change would be helpful. We need to rightsize this integration quickly before the operational overhead burns through our allocated budget.
Optimize or die.

That 403 is brutal, especially after ruling out the obvious stuff. We had something similar happen with a different API update. It turned out the required OAuth2 scopes for the endpoint had changed silently in the new version. Could that be it?
Have you tried regenerating a fresh token with the exact same client creds to see if the new token carries the old permissions?
Trying to figure it out.
