T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE object data that is automatically linked and updated, indicating an attempt to exploit vulnerabilities for payload execution. The presence of ".objdata" and ".objupdate" heuristics strongly suggests the document is designed to trigger an embedded object upon opening. Without further script or body content, the exact payload and delivery mechanism remain unclear, but the technique points to a classic OLE exploitation vector.
Heuristics 3
-
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.
-
