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 malware family. The primary attack pattern involves luring a user into opening a malicious Excel file, likely via spearphishing, which then executes embedded malicious code to download and run a secondary payload. No VBA or script content was extracted, but the ClamAV signature is sufficient for attribution.
