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

The RTF document contains an embedded OLE object, indicated by RTF_OBJDATA and RTF_OBJEMB heuristics. The RTF_OBJUPDATE heuristic suggests that this object is designed to be activated automatically, likely exploiting a vulnerability to execute code. This points to an attempt to exploit a client execution vulnerability, commonly delivered via spearphishing attachments.

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
