MITRE ATT&CK

T1059.005 Visual Basic

The file is identified as a malicious OLE executable by ClamAV with the signature Xls.Trojan.Laroux-1. Static analysis detected VBA macros, specifically an Auto_Open macro, which is a common technique for executing malicious code upon opening the document. The presence of the Auto_Open macro strongly suggests the intent to automatically run malicious code, likely to download and execute a second-stage payload.
