The critical heuristic firing indicates exploitation of CVE-2017-0199 via an OLE2Link object, which is designed to load remote content. The embedded URL, 'https://wegivebestvalurforthepeophogivingmethbestgoodthingserneedbest.busienss@link.scogo.in/9b7H7K', is highly suspicious and likely serves as the download location for a second-stage payload. The 'SE_INVOICE_LURE' heuristic suggests a social engineering pretext related to invoices or payments.

Heuristics 4

  • 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.
  • Fake invoice / payment lure low SE_INVOICE_LURE
    Document contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
  • 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.
