T1204.002 Malicious File
T1059.001 PowerShell
The sample is an RTF document containing embedded OLE objects, as indicated by the RTF_OBJDATA and RTF_OLE10NATIVE_STREAM heuristics. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be activated, likely to exploit a vulnerability within Microsoft Office. The document body is heavily obfuscated and does not provide clear textual lures. No scripts were extracted from this sample. The primary attack vector appears to be the exploitation of OLE object handling within the RTF format.
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
