MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The RTF document contains OLE object data and uses \objupdate to force OLE activation, indicating an attempt to exploit vulnerabilities or execute embedded objects. The high-severity RTF_OBJUPDATE heuristic suggests that this mechanism is intended to trigger the execution of malicious content. While no specific payload or URL was directly extracted, the technique strongly implies a downloader or exploit delivery mechanism.

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 2 \objdata section(s) — embedded OLE objects
