MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious File

The file is an RTF document containing OLE object data, as indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this OLE object is designed to be activated, likely leading to the execution of a malicious payload. The document body is heavily obfuscated and does not provide clear intent, but the heuristics strongly suggest a malicious OLE object is embedded. No specific family could be identified.

Heuristics 2

  • \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
