T1203 Exploitation for Client Execution
The critical heuristic firing indicates exploitation of CVE-2017-0199, which is a known vulnerability used to download and execute remote code. The embedded URL http://ir.cx/TLhxf is highly suspicious and likely points to the secondary payload. No VBA macros were found to be executable, but the presence of the exploit is sufficient evidence of malicious intent.
Heuristics 3
-
OLE2Link / URL Moniker → remote loader — CVE-2017-0199 critical CVE likely CVE_2017_0199Document 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_MACROSDocument contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
-
Embedded URL info EMBEDDED_URLOne 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://ir.cx/TLhxf
