The RTF document contains embedded OLE object data and an \objupdate directive, indicating an attempt to automatically activate the embedded object upon opening. This is a common technique for delivering malicious payloads. While no specific script was extracted, the presence of OLE object data strongly suggests an exploit or downloader is embedded within. The SHA256 hash is included as a primary identifier.

Heuristics 2

  • \objupdate forces OLE activation high RTF_OBJUPDATE
