T1059.001 PowerShell
T1204.002 Malicious File
The file is an Excel document containing VBA macros, specifically a Workbook_Open macro that calls the Shell() function. This indicates the macro is designed to execute an external command upon opening. The presence of 'macros.bas' and the critical heuristic for Shell() call in VBA strongly suggest the macro's intent is to download and execute a second-stage payload. The document body content appears to be financial or employee data, likely used as a lure.
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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
