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

The RTF document contains OLE object data and an \objupdate directive, indicating an attempt to exploit a vulnerability related to OLE object activation. This suggests the file is designed to execute malicious code upon opening, likely as part of a spearphishing campaign. No specific family could be identified, and no further IOCs were extracted.

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
