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

The RTF document contains OLE object data and an \objupdate directive, indicating an attempt to exploit a vulnerability and activate embedded objects. This is a common technique for delivering secondary payloads, although no specific payload or download URL was directly extracted from this sample. The presence of OLE object data strongly suggests a malicious intent to execute arbitrary code.

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
