The RTF document contains an OLE object with an \objupdate directive, indicating an attempt to activate embedded content. The document body provides a lure, instructing the user to 'Enable editing' to bypass security measures. This suggests the file is designed to trick the user into executing malicious code, likely via macros or embedded exploits, to download further payloads.

Heuristics 3

  • \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
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
