Malware Insights
The sample is an Excel spreadsheet containing VBA macros, specifically a Workbook_Open macro, which is a common technique for malware delivery. The document body instructs the user to 'Please Enable Macros to View BoQ information', acting as a lure to bypass security settings. The presence of VBA macros and the explicit instruction to enable them strongly suggest a macro-based attack pattern aimed at tricking the user into executing malicious code. No specific family could be identified, but the behavior is consistent with a downloader or initial access payload.
