T1204.002 Malicious File
The sample is an RTF document that leverages OLE object data and automatic linking to trigger embedded content. The heuristics RTF_OBJDATA, RTF_OBJAUTLINK, and RTF_OBJUPDATE strongly indicate that the document is designed to exploit OLE object activation. This technique is commonly used to deliver and execute malicious payloads, such as downloading and running further malware. The truncated document body prevents a more specific analysis of the lure, but the OLE exploitation is the primary attack 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.
-
OLE object data medium RTF_OBJDATARTF contains 1 \objdata section(s) — embedded OLE objects
