MITRE ATT&CK
T1204.002 Malicious File T1059.005 Visual Basic

The sample is an OLE 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 provided URL. Although the VBA project itself contains no executable statements, the exploit mechanism is sufficient to classify this as malicious. The file likely attempts to download and execute a second-stage payload from the embedded URL.

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.
