The sample is an RTF document containing embedded OLE object data, with heuristics indicating the use of \objdata and \objupdate to force OLE activation. The document body contains a lure instructing the user to 'Enable editing' to bypass security settings. This suggests the document is designed to trick the user into executing embedded malicious content, likely a macro or script, which is a common delivery mechanism for malware.

Heuristics 4

  • \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
  • Embedded OLE object medium RTF_OBJEMB
    RTF contains \objemb — embedded OLE object
  • 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
