MITRE ATT&CK
T1204 Malicious Link T1059 Command and Scripting Interpreter

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 Excel format indicates a likely social engineering lure to enable macros, which would then execute the dropper functionality. No scripts or document body were extracted, but the ClamAV signature is sufficient for attribution.
