The file is an Excel spreadsheet identified by ClamAV as Xls.Dropper.QbotDocu12020-9818439-0, strongly suggesting it is a Qbot variant. Such files typically rely on social engineering to trick users into enabling macros. Once enabled, the macros likely execute a dropper functionality to download and run a secondary payload, consistent with Qbot's typical behavior.
