T1059.005 Visual Basic
T1204.002 Malicious File
The file is identified as Win.Trojan.Adnel-1 by ClamAV. High-severity heuristics indicate an OLE document with a large slack region and an auto-execution of VBA p-code using the 'Shell' command via the 'Document_Open' event. Although VBA macros could not be extracted directly due to an unsupported format, the p-code execution strongly suggests the intent to download and execute a second-stage payload.

ClamAV: Win.Trojan.Adnel-1 critical CLAMAV_DETECTIONClamAV detected this file as malware: Win.Trojan.Adnel-1
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 355,332 bytes but its declared streams total only 64,670 bytes — 290,662 bytes (82%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
-
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled 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_UNSUPPORTEDolevba could not extract VBA macros (TypeError); 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_URLOne 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)
