The critical heuristic firing indicates exploitation of CVE-2017-0199 via an OLE2Link object, which attempts to load a remote resource from the URL 'https://url.odds.team/9X68fv'. This technique is commonly used to download and execute a second-stage payload. Although the VBA project itself contains no executable statements, the OLE object's behavior is sufficient to classify this as a malicious document.

Heuristics 2

  • 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.
