The file is an Excel document containing VBA macros, with a Workbook_Open auto-execution trigger. The critical OLE_VBA_SHELL heuristic indicates that the macro attempts to execute a command via the Shell() function. While the document body appears to be legitimate pension-related information, the presence of the Workbook_Open macro and Shell() call strongly suggests that the macro is designed to download and execute a second-stage payload. No specific family could be identified.
Heuristics 5

Shell() call in VBA critical OLE_VBA_SHELLShell() call in VBA
-
Workbook_Open macro high OLE_VBA_WBOPENWorkbook_Open macro
-
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
-
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
-
