Windows · attack.mitre.org · ATT&CK Enterprise v19.2
<p>Detects anomalous use of Dynamic Data Exchange (DDE) for code execution, such as Office applications (WINWORD.EXE, EXCEL.EXE) spawning command interpreters, or loading unusual modules through DDEAUTO/DDE formulas. Correlates suspicious parent-child process relationships, registry keys enabling DDE, and module loads inconsistent with normal Office usage.</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 |
|---|---|---|
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=7 | DC0016 Module Load |
| WinEventLog:Security | EventCode=4663, 4670, 4656 | DC0050 Windows Registry Key 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 |
|---|---|
AllowedParentChildPairs | Define legitimate parent-child relationships for Office processes to reduce false positives. |
TimeWindow | Threshold for correlating Office process creation with subsequent command execution via DDE. |
SuspiciousDLLList | Maintain allow/block list of DLLs that Office is expected to load. |
