MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF document contains OLE object data and uses an \objupdate directive to force OLE activation, indicating an attempt to execute embedded code. This is a common technique for delivering secondary payloads. While no specific family is identified, the method strongly suggests a malicious intent to compromise the user's system.

Heuristics 2

  • \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
