MITRE ATT&CK
T1204.002 Malicious File: User Execution T1059.001 Command and Scripting Interpreter: PowerShell

The sample is an Excel file that exploits CVE-2017-0199, a known vulnerability for remote code execution. The heuristic indicates it attempts to load a remote resource from the URL 'https://og1.in/ikWPSd'. This suggests the file acts as a downloader for a secondary malicious payload.

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.
