MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The RTF document contains embedded OLE object data and uses \objupdate to force activation, indicating an attempt to exploit vulnerabilities for client execution. The presence of RTF_OLE10NATIVE_STREAM further supports the embedding of executable content. While no specific script was directly extracted, the structure suggests the OLE object likely contains or leads to a payload, possibly a JavaScript downloader, hence the inclusion of T1059.007.
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
