MITRE ATT&CK

T1059.001 PowerShell T1566.001 Spearphishing Attachment T1204.002 Malicious File

The RTF file contains embedded OLE objects, and the \objupdate heuristic indicates that these objects are forced to activate. This suggests the document is designed to exploit OLE vulnerabilities to execute embedded code. While no specific script was extracted, the presence of OLE objects and the activation trigger strongly imply a malicious intent, likely to download and execute a secondary payload.

Heuristics 3

\objupdate forces OLE activation high RTF_OBJUPDATE

RTF 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_OBJDATA

RTF contains 1 \objdata section(s) — embedded OLE objects
Embedded OLE object medium RTF_OBJEMB

RTF contains \objemb — embedded OLE object
