MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1059.005 Visual Basic
The sample is an Excel 4.0 (XLM) macro-enabled spreadsheet that contains an Auto_Open macro, indicating it will execute automatically when opened. It also contains a lure to enable macros. The extracted URLs are likely used to download a second-stage payload. The XLM macro sheet is too truncated to determine the exact execution flow, but the presence of Auto_Open and the embedded URLs strongly suggests a downloader or droppper functionality.
Heuristics 4
-
Excel 4.0 Auto_Open defined name critical OLE_XLM_AUTOOPEN_DEFINEDNAMEoletools recovered an Auto_Open / Auto_Close entry from an Excel 4.0 macro sheet.

-
Excel 4.0 (XLM) macro sheet present medium OLE_XLM_AUTOOPENWorkbook contains an Excel 4.0 macro sheet sub-stream — XLM is rarely seen in modern legitimate workbooks and was a major Office malware vector during 2020-2022.
-
Macro/content-enable lure medium SE_ENABLE_LUREDocument instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
-
