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 a Qbot variant. The detection name implies it functions as a dropper, likely intended to download and execute a secondary payload upon user interaction, such as enabling macros. No document body or scripts were extracted, but the heuristic firing is sufficient for attribution.
