MITRE ATT&CK
T1218.010 System Binary Proxy Execution: Regsvr32 T1059.003 Command and Scripting Interpreter: Windows Command Shell

The file is an XLSM document containing VBA macros. The document body explicitly contains a command to execute 'regsvr32' with a URL pointing to a DLL payload. This indicates the document is a dropper designed to download and execute a second-stage payload. The ClamAV detection name 'Doc.Dropper.UrsnifIT1220-9803735-0' strongly suggests the Ursnif family.
