The file is an Excel spreadsheet identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it is a Qbot variant. The primary function appears to be acting as a dropper, likely leveraging embedded macros (though not explicitly detailed in the provided evidence) to download and execute a secondary stage payload. This aligns with common Qbot distribution methods.
