MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious File
The RTF file contains OLE object data and uses an \objupdate command, indicating an attempt to embed and activate an object. This is a common technique for delivering malicious payloads. While no specific family is identified, the method suggests a downloader or exploit delivery mechanism. The embedded OLE object is the primary IOC.
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
