MITRE ATT&CK

T1059.001 PowerShell T1218.005 Client Execution: Mshta

The presence of an Auto_Close VBA macro that uses Shell to execute mshta.exe indicates a malicious intent to download and execute a secondary payload. The embedded URL, although marked as benign, is suspicious in this context. The macro's execution of mshta.exe is a strong indicator of a downloader or initial access technique.

Heuristics 5

Reference to mshta.exe high SC_STR_MSHTA

Reference to mshta.exe
Auto_Close macro high OLE_VBA_AUTOCLOSE

Auto_Close macro
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
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.
