MITRE ATT&CK
T1059.005 Visual Basic
T1204.002 Malicious File
T1059.001 PowerShell
The file is a macro-enabled Excel spreadsheet containing Auto_Open and Auto_Close macros, indicating an attempt to automatically execute code upon opening. The presence of the URLDownloadToFile API reference strongly suggests the macro's intent is to download and execute a second-stage payload from one of the embedded URLs. The VBA script itself is heavily obfuscated and truncated, making a precise analysis of its actions difficult, but the overall pattern points to a downloader.
