MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The file is an Excel document identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it is a Qbot variant designed to drop a secondary payload. The detection name implies a macro-based dropper, which is a common initial access vector for Qbot. The lack of document body text or scripts means the primary evidence is the heuristic detection name.
