The file is an Excel spreadsheet identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it's a Qbot variant. The heuristic indicates a dropper functionality, implying the spreadsheet's primary purpose is to download and execute a malicious payload upon macro enablement. No document body or scripts were extracted, but the detection name itself provides sufficient evidence for this assessment.
