The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly indicating it functions as a dropper for the Qbot malware family. The presence of macro-related heuristics suggests it likely uses embedded VBA to download and execute a secondary payload, a common Qbot delivery technique. The file's nature as an Excel document further supports a phishing or social engineering vector.
