MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF file contains multiple OLE objects, with one specifically identified as a Package object. The presence of \objupdate directives strongly suggests an attempt to automatically activate these embedded objects, likely exploiting a vulnerability to execute arbitrary code. While the specific exploit is not detailed, the overall pattern points to a malicious RTF document designed for exploitation.
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.
-
Package object class high RTF_OBJCLASS_PACKAGEOLE Package object — can wrap arbitrary files
-
OLE object data medium RTF_OBJDATARTF contains 5 \objdata section(s) — embedded OLE objects
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
