MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly indicating it's a Qbot variant designed to drop a secondary payload. The detection name suggests it's a dropper disguised as a document, likely delivered via spearphishing. No VBA or scripts were extracted, but the ClamAV signature is sufficient for attribution.
