MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects that are automatically updated and activated, indicating an attempt to execute embedded content. The presence of `RTF_OBJDATA`, `RTF_OBJAUTLINK`, and `RTF_OBJUPDATE` heuristics strongly suggests that the file is designed to exploit vulnerabilities in RTF parsing to achieve code execution. The extracted artifact `objdata_00_off00000046.bin` is likely the payload or a component thereof. The attack pattern is consistent with a malicious document designed to deliver a second-stage payload.
Heuristics 4
-
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.
-
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.
