T1559.001 Component Object Model
T1204.002 Malicious File
The RTF file contains a large amount of hex-encoded data within an OLE object, flagged by multiple high-severity heuristics. The ".objdata" section and ".objupdate" directive indicate that the embedded OLE object is designed to be automatically activated upon opening the document. This mechanism is commonly used to drop and execute secondary payloads. The extracted artifact "objdata_00_off00000094.bin" is likely the hidden payload.
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 ~2151KB of hex-encoded data inside \objdata sections — may hide a payload
-
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.
