MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.005 Visual Basic

The file is an Excel spreadsheet that exploits CVE-2017-0199 via an OLE2Link object to download a second-stage payload from the URL 'https://yamantap.me/iTf0EI?&bidet=narrow&dune=wholesale&half-sister=available&leather=craven&dessert=guttural&craftsman'. Although the VBA project contains no executable statements, the critical heuristic firing indicates the exploit is present and functional. The presence of VBA code, even if non-executable, suggests a potential vector for further malicious activity.

Heuristics 3

  • OLE2Link / URL Moniker → remote loader — CVE-2017-0199 critical CVE likely CVE_2017_0199
    Document contains an embedded OLE link object whose URL Moniker points to a remote URL. When the host file is opened, Office follows the link, downloads the URL, and processes the response based on its Content-Type (HTA -> mshta.exe, RTF → Word, etc.) — the documented CVE-2017-0199 primitive. The URL extension is not a reliable filter; servers can return different payloads to Office's user agent.
  • VBA project contains no executable statements low OLE_VBA_MACROS
    Document contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
  • 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.
    URL https://yamantap.me/iTf0EI?&bidet=narrow&dune
