T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample contains a malicious VBA macro that is obfuscated and designed to execute automatically upon opening the document. The macro utilizes CreateObject and Shell execution, indicating an intent to download and run a secondary payload. The presence of an embedded URL, although benign according to reputation, suggests a potential download mechanism.
Heuristics 6
-
Obfuscated auto-exec VBA loader critical OLE_VBA_OBFUSCATED_AUTOEXEC_LOADERAuto-exec VBA reconstructs strings with a heavy custom decoder (numeric char-array, repeated hex-string decode, or junk-token Replace removal) and feeds them to a COM-instantiation or execution sink. This obfuscated-loader shape keeps CreateObject/Shell/URL indicators out of the macro source.

Document_Open macro high OLE_VBA_DOCOPENDocument_Open macro
-
CreateObject call high OLE_VBA_CREATEOBJCreateObject call
-
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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
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
