The critical heuristic firing indicates this Excel file is detected as a Qbot dropper. This suggests the primary attack pattern is to trick the user into enabling macros, which then likely executes embedded code to download and run a secondary payload. The file's metadata and the ClamAV detection strongly support this classification.
