T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The sample is a malicious OOXML document containing an embedded OLE object. This object is identified as a risky file package that drops an auto-executable payload, specifically a JAR file. The presence of this embedded object strongly suggests an attempt to execute a secondary payload upon opening the document.
Heuristics 4
-
Ole10Native package drops an auto-executable payload critical OFFICE_PACKAGE_RISKY_FILEOLE Package displayName or fullPath ends in a directly auto-executable extension (a runnable binary or a script the default shell host runs on double-click). Embedding such a payload inside an Office document has no benign authoring use — it is a malware-delivery dropper.
-
Embedded OLE object medium OOXML_OLE_OBJECTDocument contains an embedded OLE object
-
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.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas In document text (OOXML body / shared strings)
