MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
T1059.001 PowerShell
The file is an RTF document containing embedded OLE object data, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this embedded object is designed to be activated, likely exploiting a vulnerability to execute code. The presence of an extracted artifact, objdata_00_off00000b94.bin, further supports this. The document body is heavily obfuscated and unreadable, providing no direct clues to the lure.
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.
