MITRE ATT&CK
T1204.002 Malicious File

The critical heuristic firing indicates exploitation of CVE-2017-0199, which is a known vulnerability used to download and execute remote content. The extracted URL is highly suspicious and likely points to the secondary payload. The file is an Excel spreadsheet, suggesting a macro-based or exploit-driven delivery mechanism.

Heuristics 1

  • 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.
