# T1197 - BITS Jobs

## SOC Recommendation
Investigate BITS Jobs activity in the context of Stealth/Persistence/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 |
|---|---|---|
| Relay Pattern Analysis | Detect | Monitor for Relay Pattern Analysis indicators relevant to this technique. |
| Outbound Traffic Filtering | Isolate | Apply Outbound Traffic Filtering to contain the blast radius once this technique is observed. |

## 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
DeviceProcessEvents
| where 
    (FileName =~ "bitsadmin.exe" or column_ifexists('ProcessVersionInfoOriginalFileName','ColumnNotAvailable') =~ 'bitsadmin.exe')
    and ProcessCommandLine has_any ('/Transfer','/AddFile', '/AddFileSet','/AddFileWithRanges')
| extend 
    ParsedCommandLine = parse_command_line(ProcessCommandLine,'windows')
| extend     
    RemoteUrl = tostring(ParsedCommandLine[-2]),
    LocalFile= tostring(ParsedCommandLine[-1]),
    Direction = iff(ProcessCommandLine has "/Upload", 'Upload', 'Download')

    ProcessCommandLine
| extend HostName = iff(DeviceName has '.', substring(DeviceName, 0, indexof(DeviceName, '.')), DeviceName)
| extend DnsDomain = iff(DeviceName has '.', substring(DeviceName, indexof(DeviceName, '.') + 1), "")
```

## Escalation Criteria
- BITS Jobs 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.
