The critical OLE_VBA_SHELL heuristic indicates the presence of a Shell() call within the VBA macros. The Auto_Open macro, identified by OLE_VBA_AUTO, is designed to execute automatically upon opening the document. The script reconstructs the string "https://www.bitly.com/ehwuioqhdnkjaswqueiljka" and passes it to the Shell() function, indicating it likely downloads and executes a second-stage payload from this URL.

Heuristics 5

Shell() call in VBA critical OLE_VBA_SHELL

Shell() call in VBA
Auto_Open macro high OLE_VBA_AUTO

Auto_Open macro
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled 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_TRIAGE

One 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_MACROS

Document contains VBA macro code
