T1059.005 Visual Basic T1059.003 Windows Command Shell T1105 Ingress Tool Transfer

The critical ClamAV detection and high-severity heuristics for VBA macros, Document_Open, GetObject, and cmd.exe indicate malicious intent. The Document_Open macro executes a command that downloads a second-stage payload from 'http://transfintor.sh/gintot/gj04sqKk7O/boat.into' to 'C:\Users\Public\ggxnw.exe' and then executes it. This indicates a downloader or droppper functionality.

cmd.exe reference in VBA
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.
