T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The file is an Excel document containing VBA macros, with a high-confidence heuristic indicating an Auto_Open macro that uses CreateObject to execute code. The auto_open subroutine attempts to create a file named VERA.XLS in the application startup path, suggesting a downloader or dropper functionality. The script's obfuscation and truncation prevent a full analysis of its ultimate payload, but the intent is to execute arbitrary code.
Heuristics 5
-
Auto_Open macro high OLE_VBA_AUTOAuto_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
-
Macro capabilities present but unconfirmed info MACRO_CAPABILITY_UNCORROBORATEDThe document's VBA exposes execution capabilities (Shell/WScript/CreateObject/auto-exec) but nothing corroborates malicious intent — no obfuscation, memory-exec primitive, download+exec chain, encoded payload, LOLBin, DDE, AV hit, or suspicious URL. The verdict was capped at 'suspicious' so legitimate macro-heavy business documents are not flagged malicious on capability presence alone.
