T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The RTF document contains OLE object data that is triggered for activation via \objupdate, indicating an attempt to execute embedded content. This is a common technique for delivering secondary payloads. While no specific family is identified, the method strongly suggests a malicious document designed for initial compromise.
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
