T1566.002 Spearphishing Attachment T1204.002 Malicious File

The RTF document contains OLE object data that is configured to activate automatically upon opening, indicated by RTF_OBJDATA and RTF_OBJUPDATE heuristics. This suggests an attempt to exploit a vulnerability or deliver a malicious payload via embedded OLE objects. No specific family could be identified, and no further IOCs were extracted.

Heuristics 3

  • Ole10Native stream in RTF OLE object high CVE related RTF_OLE10NATIVE_STREAM
    RTF contains an embedded OLE object with an Ole10Native stream. This is a strong payload-container signal and is related to Word/OLE exploit delivery, but it is not specific enough on its own to assign a CVE.
  • \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 2 \objdata section(s) — embedded OLE objects
