The sample leverages the CVE-2017-0199 vulnerability, which is a known method for remote code execution. The embedded URL, 'https://goodthingswithbetterthingswithgoodcapturewithgniceworkingskillformeg.business@link.scogo.in/zjteAz', is highly suspicious and likely serves as the initial download point for a secondary malicious payload. Although VBA macros were present, they contained no executable statements, indicating the exploit relies on the OLE vulnerability itself.

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.
