MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious File

The RTF document contains embedded OLE object data and uses an \objupdate directive, indicating an attempt to automatically activate the embedded object. This is a common technique for delivering malicious content. No document body text or scripts were extracted, limiting the ability to determine the exact payload or family. The heuristics suggest a malicious RTF document designed to exploit embedded objects.

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
