The RTF document contains embedded OLE object data and an \objupdate directive, indicating an attempt to activate embedded content. The document body presents a lure related to financial audits, instructing the user to 'Enable editing', which is a common tactic to bypass macro security. This suggests the document is designed to trick the user into enabling malicious content, likely to download and execute a second-stage payload.

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
