MITRE ATT&CK
T1204.002 Malicious File
T1566.001 Spearphishing Attachment
The RTF document contains embedded OLE objects with automatic linking and update triggers, indicating an attempt to execute embedded content. Heuristics suggest a large amount of hex-encoded data within the OLE object, likely hiding a payload. The extracted artifact 'objdata_00_off00000ba1.bin' is a strong indicator of the embedded malicious content.
Heuristics 5
-
Automatically linked OLE object high RTF_OBJAUTLINKRTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
-
\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.
-
Large hex data blocks in OLE object high RTF_EXCESSIVE_HEXRTF contains ~2179KB of hex-encoded data inside \objdata sections — may hide a payload
-
OLE object data medium RTF_OBJDATARTF contains 2 \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.
