The sample is an Excel spreadsheet containing VBA macros, specifically a Workbook_Open macro that utilizes the Shell() function. This indicates an attempt to execute arbitrary code. The document body presents a form related to financial applications, suggesting a phishing or scam lure. The presence of VBA macros and the use of Shell() are strong indicators of malicious intent, likely to download and execute a second-stage payload.

-
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.
