MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects that are automatically linked and updated, indicating an attempt to execute embedded code. The presence of `RTF_OBJDATA`, `RTF_OBJAUTLINK`, and `RTF_OBJUPDATE` heuristics strongly suggests that the document is designed to exploit OLE object handling to deliver a secondary payload. The extracted `objdata_00_off000016d6.bin` artifact is likely the embedded malicious content.
Heuristics 4
-
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 1 \objdata section(s) — embedded OLE objects
-
