The file is an Excel spreadsheet identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly indicating it functions as a dropper for the Qbot banking trojan. The primary attack pattern involves luring the user to open the malicious spreadsheet, which then executes a payload. No VBA or scripts were extracted, but the ClamAV signature is sufficient for attribution.
