MITRE ATT&CK
T1204 Malicious Link T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The file is a malicious Office document containing embedded OLE packages, one of which has a .vbe extension, indicating a Visual Basic script. The heuristic 'SE_ENABLE_LURE' confirms that the document instructs the user to enable macros or editing, a common tactic for malware droppers. This suggests the embedded script is intended to be executed upon user interaction, likely to download and execute a second-stage payload.

Heuristics 3

  • Ole10Native package carries executable/script file type high OFFICE_PACKAGE_RISKY_FILE
    OLE Package displayName or fullPath ends in an executable or script-capable extension. Even without UI extension spoofing, embedding a runnable payload inside an Office document is a high-risk delivery pattern.
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • Embedded URL info EMBEDDED_URL
    One 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.
