T1059.001 PowerShell
T1204.002 Malicious File
The RTF document contains an OLE object that is configured to update automatically upon opening. This technique is commonly used to deliver malicious payloads. While the specific payload and its ultimate destination are not detailed in the provided evidence, the presence of the OLE object and the auto-update trigger strongly suggest a malicious intent to execute code. The file's SHA256 hash is included as a primary indicator.
Heuristics 3
-
\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
