T1204.002 Malicious File
T1059.001 PowerShell
The RTF document contains embedded OLE objects, with heuristics indicating that \objupdate forces OLE activation and the Ole10Native stream is present. This suggests the document is designed to exploit vulnerabilities in OLE object handling to execute arbitrary code upon opening. No specific malware family could be identified, but the attack pattern is consistent with a malicious document leveraging embedded objects for initial execution.
Heuristics 4
-
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
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
