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 exploit a vulnerability to activate and execute the embedded object. This is a common technique for delivering malicious payloads. No specific family could be identified, and no URLs or scripts were extracted to further detail the payload's behavior.

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
