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

The sample is an RTF document containing embedded OLE object data. The presence of the RTF_OBJUPDATE heuristic indicates that the document is configured to automatically activate these embedded objects upon opening, which is a common technique for delivering malicious payloads. No document body text or scripts were extracted, limiting further analysis of the specific payload or 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 1 \objdata section(s) — embedded OLE objects
