MITRE ATT&CK

T1204.002 Malicious File T1059.005 Visual Basic

The critical heuristic firing indicates exploitation of CVE-2017-0199 via an OLE2Link object, which attempts to download a remote payload from http://ilang.in/IInHM. Although the VBA project contains no executable statements, the presence of the OLE object and the embedded URL strongly suggest a remote code execution attempt. The file is an Excel spreadsheet, likely used as a lure to trick users into opening it and triggering the exploit.

Heuristics 3

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.
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.

URL http://ilang.in/IInHM
