The document presents itself as a text utility for font conversion and date insertion, likely to entice the user to enable macros. The presence of VBA macros and a high-severity heuristic firing for ShellExecute API usage indicates that the macros are designed to execute arbitrary commands. The Auto_Open macro specifically triggers execution via Shell, suggesting it downloads and executes a second-stage payload. The extracted artifact 'macros.bas' is the VBA macro source.
Heuristics 4
-
Reference to ShellExecute API high SC_STR_SHELLEXECReference to ShellExecute API
-
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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
Suspicious extracted artifact medium 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.
