MITRE ATT&CK
T1059.001 PowerShell
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects, with evidence of OLE object data and activation triggers. This strongly suggests the file is designed to exploit OLE vulnerabilities to execute embedded code. The heuristics indicate that the embedded object is likely a secondary payload. Without further script analysis or network indicators, the exact family remains unknown, but the attack pattern is consistent with a downloader or initial access mechanism.
Heuristics 4
-
\objupdate forces OLE activation high RTF_OBJUPDATERTF 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_OBJDATARTF contains 1 \objdata section(s) — embedded OLE objects
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
