The critical ClamAV heuristic firing, 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggests this is a Qbot variant designed as a dropper. The file type (XLSX) and the heuristic name indicate it likely uses macro-based execution to download and run a secondary payload, a common Qbot delivery method.
