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 |
|---|---|---|
| WinEventLog:PowerShell | EventCode=4103, 4104, 4105, 4106 | DC0064 Command Execution |
| WinEventLog:Sysmon | EventCode=23 | DC0040 File Deletion |
| WinEventLog:Security | EventCode=4663, 4670, 4656 | DC0061 File Modification |
| m365:exchange | Transport Rule Modification | DC0038 Application Log Content |
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 |
|---|---|
MailstorePath | Outlook files in AppData\Local\Comms\Unistore\data |
TransportRuleNames | Target suspicious rule changes (e.g., header removal) |
PowerShellCommandMatch | Regex match on `Remove-MailboxExportRequest` and similar Exchange cmdlets |
