The sample contains a Workbook_Open macro that executes Wscript.Shell to run a batch file and a VBScript. The VBScript is heavily obfuscated but appears to download payloads from multiple URLs. The presence of Wscript.Shell and the execution of external scripts indicate a downloader or dropper functionality.
