The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it functions as a dropper for the Qbot banking trojan. While no VBA or scripts were explicitly extracted, the detection name implies macro-based execution to download and install the primary Qbot malware. The file's nature as an Excel document further supports a phishing or social engineering vector.
