The file is an Excel spreadsheet flagged by ClamAV as a dropper, specifically 'Xls.Dropper.QbotDocu12020-9818439-0'. This indicates it likely contains malicious macros intended to download and execute a secondary payload. The presence of this specific ClamAV detection strongly suggests a Qbot-related dropper, though without further analysis of embedded scripts or network activity, the exact family remains uncertain.
