T1059.005 Visual Basic
T1203 Exploitation for Client Execution
The file is an Excel spreadsheet containing Excel 4.0 macros, which are known to be used for malicious purposes. The critical heuristic firing confirms the presence of these macros. While the macro content is truncated, the presence of XLM macros strongly suggests an attempt to execute arbitrary commands, likely for downloading and executing a second-stage payload. The specific commands or URLs are not visible due to truncation.

Excel 4.0 macro sheet (1 sheet(s)) critical OOXML_XLM_MACROSHEETSpreadsheet contains an Excel 4.0 (XLM) macro sheet — XLM was a major Office malware vector during 2020-2022 and evaded many VBA-focused controls before Microsoft tightened XLM defaults. Even legitimate XLM use is rare in modern workbooks. The macro sheet is stored as XLSB/BIFF12 binary content, which many XML-only OOXML scanners miss.
