MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
T1059.001 PowerShell
The file is an RTF document containing embedded OLE objects, with a high-confidence heuristic indicating that \objupdate forces OLE activation. This suggests the document is designed to exploit vulnerabilities in how RTF handles embedded objects, likely to execute arbitrary code. The presence of objdata and objemb heuristics further supports this. Without a document body or script content, the exact payload and delivery mechanism remain unclear, but the RTF object exploitation is a strong indicator of a malicious downloader.
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
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
