MITRE ATT&CK
T1559.001 Component Object Model Hijacking

The file is a malicious OLE document that utilizes an Ole10Native package to drop an executable payload. The heuristic 'OFFICE_PACKAGE_RISKY_FILE' indicates that the package is designed to auto-execute a payload, identified as a JAR file. The extracted artifact 'ole10native_00.bin' is the dropped payload.

Heuristics 2

  • Ole10Native package drops an auto-executable payload critical OFFICE_PACKAGE_RISKY_FILE
    OLE 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.
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One 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.
