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

The sample is an Excel file that exploits CVE-2017-0199, a known vulnerability for remote code execution. The heuristic indicates it acts as a remote loader, downloading content from the URL https://mycon.link/W3hxsp?&pocket-watch=macabre&fireman=supreme&cooking=lazy&swiss. Although VBA macros are present, they contain no executable statements, suggesting the exploit is directly leveraged by the OLE object rather than through macro execution.

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://mycon.link/W3hxsp?&pocket-watch=macabre&fireman=supreme&cooking=lazy&swiss
