Engine-generated findings
These come from the engine's cross-resource analysis rather than the catalog, so their ids are families, not single checks.
ATTACK_PATH_*— Attack paths- Chains that cross resources: an internet-reachable entry point, an identity it can use, and the IAM permissions that lead from there to account-wide control.
AWS_XREF_*— Cross-resource correlations- Issues that are only visible when you look at how several resources interact, not at any one resource on its own.
AWS_FUSION_*— Cost and security together- Findings that need a cost signal and a security signal on different resources in the same code, such as accelerator compute next to an administrator-equivalent IAM policy.
AWS_CRED_*— Credentials written into code- Literal credentials of recognisable shapes (AWS access key ids, private keys, provider tokens) in resource attributes, variable defaults and variable files.
AWS_CFN_*— CloudFormation only- Findings with no Terraform twin, such as a NoEcho parameter whose value flows into Outputs, or a nested stack pulled from an unpinned template URL.
