MITRE ATT&CK

T1566.001 Phishing: Spearphishing Attachment T1204.002 Malicious File: User Execution

The RTF file contains OLE object data and heuristics indicate that \objupdate forces OLE activation, suggesting it's designed to execute embedded content. The presence of an embedded OLE object further supports this. While no specific family is identified, the mechanism points to a malicious document designed for exploitation.

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
