MITRE ATT&CK
T1566.001 Spearphishing Attachment

The RTF document contains OLE object data and an \objupdate directive, indicating an attempt to execute embedded content. While no specific script was extracted, the heuristics suggest a malicious intent to exploit OLE object activation. The file's SHA256 hash is provided as a primary IOC.

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
