MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The ClamAV heuristic explicitly identifies the file as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it is a Qbot dropper disguised as an Excel document. The file's metadata indicates it is an older Excel file, which is a common format for macro-based malware delivery. The primary function appears to be downloading and executing a Qbot payload.
