MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

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