T1059.005 Visual Basic
T1204.002 Malicious File
The sample is an OLE document with a high-risk anomaly and detected VBA macros. A critical heuristic firing indicates the presence of a Shell() call within the VBA code, specifically within a Document_Open macro. This suggests the macro is designed to execute arbitrary commands upon opening the document, likely to download and execute a secondary payload. No specific family could be identified.
Heuristics 5
-
VBA macros detected medium 2 related findings OLE_VBA_MACROSDocument contains VBA macro code
-
Shell() call in VBA critical OLE_VBA_SHELLShell() call in VBA
-
Document_Open macro high OLE_VBA_DOCOPENDocument_Open macro
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 214,784 bytes but its declared streams total only 57,265 bytes — 157,519 bytes (73%) 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).
-
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)
