MITRE ATT&CK
T1566.002 Spearphishing Attachment

The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly indicating it belongs to the Qbot family and functions as a dropper. The primary attack pattern involves luring the user into opening a malicious Excel file, likely via spearphishing, which then executes a secondary payload. No VBA scripts or document body text were extracted, but the ClamAV signature is sufficient for attribution and confidence.
