MITRE ATT&CK

T1204.002 Malicious File T1059.005 Visual Basic

The sample is an Excel file that exploits CVE-2017-0199 via a URL moniker to download and execute a remote payload from https://zhort.de/hllyO1. Although VBA macros were present, they contained no executable statements, indicating the exploit is likely embedded within the OLE structure itself. The embedded URL is the primary indicator of compromise.

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.
