MITRE ATT&CK

T1059.005 Visual Basic T1059.003 Windows Command Shell T1204.002 Malicious File

The sample contains VBA macros, including an AutoOpen macro that utilizes the Shell() function to execute arbitrary commands. This is a strong indicator of a downloader, consistent with the Emotet family identified by ClamAV. The primary function of the embedded VBA script is to execute a command-line process, likely to download and run a secondary payload.

Heuristics 8

ClamAV: Doc.Downloader.Emotet-6789247-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Downloader.Emotet-6789247-0
Suspicious cmd.exe invocation with execution flag high SC_STR_CMD

Suspicious cmd.exe invocation with execution flag
AutoOpen macro high OLE_VBA_AUTOOPEN

AutoOpen 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.
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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.
