MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
T1059.001 PowerShell
The RTF document contains an OLE object with ".objupdate" which forces activation, indicating an attempt to exploit a vulnerability. The presence of an embedded OLE object and the RTF object data heuristic strongly suggest that this file is designed to drop and execute a malicious payload. No document body text was available for further analysis, and no scripts were extracted.
Heuristics 3
-
\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
-
