MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
T1059.001 PowerShell
The file is an RTF document containing OLE object data, which is a common delivery mechanism for exploits. The presence of RTF_OBJDATA and RTF_OBJUPDATE heuristics indicates that the document is designed to trigger an OLE object activation, likely leading to the execution of embedded malicious code. The extracted document body is heavily obfuscated and does not provide clear intent, but the heuristics strongly suggest an exploit attempt.
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
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
