MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV and contains VBA p-code that executes a shell command upon opening the document. Although VBA macros could not be directly extracted due to an unsupported format, the heuristic firing indicates the presence of an auto-executing macro designed to run a shell command. This suggests the document is likely a malicious attachment intended to deliver a secondary payload.

Heuristics 4

ClamAV: Doc.Malware.00536d-6707118-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Malware.00536d-6707118-0
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.
Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTED

olevba could not extract VBA macros (AssertionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
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.

URL http://schemas.openxmlformats.org/drawingml/2006/main In document text (OLE body)
