MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly indicating it functions as a dropper for the Qbot banking trojan. The primary attack pattern involves luring the user into opening a malicious Excel file, which then executes a payload. While no specific VBA or script content was extracted, the ClamAV signature and file type suggest a macro-enabled document is used to initiate the infection chain.
