MITRE ATT&CK
T1204.002 Malicious File Execution: Malicious File

The sample is an OLE2Link object that exploits CVE-2017-0199. This vulnerability allows the object to act as a remote loader, downloading and executing a secondary payload from the URL 'https://og1.in/2Rxzb3'. The exploit targets the URL Moniker component to achieve remote code execution.

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.
