T1566.001 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious File
The RTF file contains OLE object data and an \objupdate directive, indicating an attempt to embed and activate an object. This is a common technique for delivering malicious payloads. While no specific family is identifiable, the method suggests a downloader or exploit delivery mechanism. The document body is heavily obfuscated and does not provide clear intent.
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
