The Document_Open VBA macro is triggered upon opening the malicious Word document. It constructs a batch file named 'god.bat' in the public documents directory. This batch file contains a command to download a second-stage executable from 'http://ddl8.data.hu/get/210646/13081337/YConsoleApp117all.exe' and save it as 'muchbehind.exe' in the same directory. Finally, it executes the downloaded file. The VBA macro uses GetObject to create and write to the batch file, and then another GetObject call to execute it.

GetObject call high OLE_VBA_GETOBJGetObject 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
