The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it is a Qbot variant designed to drop a secondary payload. The XLSX file format and the detection name indicate a likely phishing or social engineering lure to execute malicious code. No scripts were extracted, but the dropper nature implies it attempts to download and run further malware.
