<p>Detection of suspicious enumeration of cloud storage objects via API calls such as AWS S3 ListObjectsV2, Azure List Blobs, or GCP ListObjects. Correlate access with account role, user context, and prior authentication activity to identify anomalous usage patterns (e.g., unusual account, unexpected regions, or large-scale enumeration in short time windows).</p>

Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| AWS:CloudTrail | ListObjectsV2 | DC0017 Cloud Storage Enumeration |
| AWS:CloudTrail | GetObject, CopyObject | DC0025 Cloud Storage Access |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
TimeWindow | Correlation window (e.g., multiple enumeration calls within 5 minutes) may indicate automated discovery versus normal user activity. |
UserContext | Expected service accounts and IAM roles that regularly enumerate storage; deviations may indicate suspicious activity. |
RegionScope | Unusual enumeration of buckets across multiple geographic regions in short succession may indicate adversary reconnaissance. |
