T1559.002 Component Object Model
T1204.002 Malicious File
The RTF document contains multiple OLE objects, including automatically linked objects that are updated via \objupdate. This suggests the document is designed to exploit vulnerabilities related to OLE object activation and embedding, likely to deliver a secondary payload. No document body or script content was available for further analysis.
Heuristics 5
-
Composite Moniker in RTF OLE object high RTF_COMPOSITE_MONIKER_RELATEDRTF contains Composite Moniker CLSID in OLE object context, but no nearby scriptlet/SCT payload was confirmed. Treat as related moniker attack-surface evidence rather than proof of CVE-2017-8570 exploitation.
-
Automatically linked OLE object high RTF_OBJAUTLINKRTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
-
\objupdate forces OLE activation high RTF_OBJUPDATERTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
-
OLE object data medium RTF_OBJDATARTF contains 3 \objdata section(s) — embedded OLE objects
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
