MITRE ATT&CK
T1566.001 Phishing: Spearphishing Attachment T1204.002 Malicious File: User Execution

The RTF document contains OLE object data and is configured to automatically update and activate these objects. This suggests an attempt to exploit vulnerabilities associated with OLE object handling, likely to execute embedded code or download a secondary payload. The heuristics indicate a high likelihood of malicious OLE object activation, which is a common technique for delivering malware.

Heuristics 3

  • Automatically linked OLE object high RTF_OBJAUTLINK
    RTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
  • \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
