MITRE ATT&CK
T1203 Exploitation for Client Execution

The file is an OLE object that triggers CVE-2017-0199, a known vulnerability for remote code execution. This vulnerability is used to download a secondary payload from the URL 'https://gacorbos.me/M15pgZ?&boar=thankful&motion=rambunctious&jaguar=ashamed&velodrome'. The embedded URL indicates a malicious intent to fetch and execute external content.

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.
  • 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.
