The RTF document contains OLE object data and triggers OLE activation, indicating an attempt to execute embedded content. While no specific script was extracted, the heuristics suggest a malicious OLE object is present, likely leading to further payload execution. The file's SHA256 hash is provided as a primary IOC.

Heuristics 2

  • \objupdate forces OLE activation high RTF_OBJUPDATE

  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \objdata section(s) — embedded OLE objects
