MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it functions as a dropper for the Qbot malware family. The primary attack pattern involves luring a user into opening a malicious Excel file, which then likely executes embedded malicious code to download and run a further stage. No document body or scripts were extracted, but the heuristic detection is highly indicative of Qbot's typical delivery mechanism.
