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

The file is an Excel spreadsheet that exploits CVE-2017-0199, a known vulnerability for remote code execution. The exploit attempts to download a secondary payload from the provided URL. Although the VBA project contains no executable statements, the critical heuristic firing indicates the exploit is present and functional. The embedded URL is the primary indicator of compromise.

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 http://00000015353126315/httpsappexchange.salesforce.comappxListingDetaillistingId=a0N3A00000EFntJUN3A00000EFntJUN3A00000EFntJUN3A00000EFntT.php In document text (OLE body)
