MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The critical ClamAV detection and high-severity heuristics for OLE_VBA_MACROS, OLE_VBA_DOCOPEN, OLE_VBA_GETOBJ, and OLE_VBA_PCODE_AUTOEXEC_EXEC strongly indicate the presence and execution of malicious VBA macros. The ClamAV signature specifically names this as an Emotet variant, a known banking trojan and downloader. The document body is heavily obfuscated and unreadable, providing no direct clues to the lure, but the macro execution is the primary indicator of malicious intent, likely to download and execute a second-stage payload.

GetObject call
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.
