MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The RTF document contains embedded OLE objects, indicated by RTF_OBJDATA and RTF_OBJEMB heuristics. The RTF_OBJUPDATE heuristic suggests that the embedded object is configured to activate automatically upon opening, which is a common technique for exploiting vulnerabilities or delivering malicious content. No specific family could be identified, and no further IOCs were extracted.

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