# T1651 - Cloud Administration Command

## SOC Recommendation
Investigate Cloud Administration Command activity in the context of Execution: confirm scope, affected host/identity, and whether it matches expected administrative behaviour before deciding this is benign.

## D3FEND Mappings
| D3FEND Technique | Relationship | Practical SOC Action |
|---|---|---|
| Network Traffic Analysis | Detect | Monitor for Network Traffic Analysis indicators relevant to this technique. |

## Investigation Steps
1. Review Defender for Endpoint / Defender XDR alerts and timeline for the affected host or identity.
2. Check Sentinel analytics rules and incidents correlated with this technique.
3. Review Entra ID sign-in and audit logs if the technique involves an identity or cloud resource.

## Evidence to Collect
- Host or resource affected
- Account or identity involved
- Timestamp of the activity
- Related process, file, or network artifact
- Any preceding or follow-on alerts

## Response Actions
| Action | Risk | Automation Safe | Approval Required |
|---|---|---|---|
| Contain the affected host or account | Medium | No | Yes |
| Collect and preserve evidence | Low | Yes | No |

## KQL
```kql
let command_executed = AWSCloudTrail
| where EventName in ("SendCommand","CreateAssociation") and isempty(ErrorCode) and isempty(ErrorMessage)
| extend params = tostring(parse_json(RequestParameters).parameters)
| extend s3bucketCommand = tostring(parse_json(RequestParameters).outputS3BucketName)
| extend s3bucketAssociation = tostring(parse_json(RequestParameters).outputLocation.s3Location.outputS3BucketName)
| where isnotempty(params)
| extend commandId = tostring(parse_json(ResponseElements).command.commandId)
| extend associationId = tostring(parse_json(ResponseElements).associationDescription.associationId)
| extend executionId = iff(isnotempty(commandId), commandId, associationId)
| extend s3bucket = iff(isnotempty(s3bucketCommand), s3bucketCommand, s3bucketAssociation)
| extend UserIdentityUserName = iff(isnotempty(UserIdentityUserName), UserIdentityUserName, tostring(split(UserIdentityArn,'/')[-1]));
AWSCloudTrail
| where EventName == "PutObject" and isempty(ErrorCode) and isempty(ErrorMessage)
| extend s3bucket = tostring(parse_json(RequestParameters).bucketName)
| mv-expand todynamic(Resources)
| extend accountId=tostring(todynamic(Resources.['accountId']))
| where Resources contains "accountId" and accountId <> RecipientAccountId
| join command_executed on s3bucket
| extend UserIdentityArn = iif(isempty(UserIdentityArn), tostring(parse_json(Resources)[0].ARN), UserIdentityArn)
| extend UserName = tostring(split(UserIdentityArn, '/')[-1])
| extend AccountName = case( UserIdentityPrincipalid == "Anonymous", "Anonymous", isempty(UserIdentityUserName), UserName, UserIdentityUserName)
| extend AccountName = iif(AccountName contains "@", tostring(split(AccountName, '@', 0)[0]), AccountName),
  AccountUPNSuffix = iif(AccountName contains "@", tostring(split(AccountName, '@', 1)[0]), "")
```

## Escalation Criteria
- Cloud Administration Command activity observed on a privileged account or critical system.
- Activity follows or precedes other suspicious behaviour in the same investigation.
- Automated triage cannot confidently rule out malicious intent.

## False Positive Considerations
- Legitimate administrative or maintenance activity matching this pattern.
- Approved security testing or red team exercise.
- Known benign software producing similar telemetry.
