T1566.001 Spearphishing Attachment
T1204.002 Malicious File
T1027 Obfuscated Files or Information
The RTF document contains OLE object data and triggers an ".objupdate" event, indicating it's designed to automatically activate embedded objects. This is a common technique for delivering secondary payloads or exploits. No specific family could be identified, and no further IOCs were extracted from the limited document body.
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 1 \objdata section(s) — embedded OLE objects
