MITRE ATT&CK

T1204 User Execution: Malicious Link T1059 Command and Scripting Interpreter

The RTF file contains an OLE object and an \objupdate directive, indicating an attempt to activate embedded content. The heuristic SE_ENABLE_LURE confirms that the document instructs the user to enable editing, a common social engineering tactic to bypass security measures. While no scripts were extracted, the presence of OLE objects and the lure suggest the file is designed to execute embedded malicious code upon user interaction.

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
Macro/content-enable lure medium SE_ENABLE_LURE

Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
