MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File T1027 Obfuscated Files or Information

The RTF file contains embedded OLE objects and uses the \objupdate directive, which is a common technique for executing embedded code. The heuristics indicate the presence of OLE object data and an embedded OLE object that is forced to activate. This suggests the file is designed to exploit vulnerabilities or trick the user into executing a malicious payload upon opening.

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
