T1566.002 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains OLE object data and uses \objupdate to force OLE activation, indicating an attempt to exploit vulnerabilities related to embedded objects. The Ole10Native stream further suggests the presence of a malicious embedded object. These heuristics strongly point towards an exploit delivery mechanism.
Heuristics 3
-
Ole10Native stream in RTF OLE object high RTF_OLE10NATIVE_STREAMRTF contains an embedded OLE object with an Ole10Native stream. This is a strong payload-container signal and is related to Word/OLE exploit delivery, but it is not specific enough on its own to assign a CVE.
-
\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 2 \objdata section(s) — embedded OLE objects
